Unless you’ve spent the majority of your life living under a rock, you’re well aware of the laundry list of benefits that come with staying adequately hydrated. While drinking the proper amount of water each day is critical to our wellbeing, the majority of people don’t drink nearly as much water as they’re supposed to.

While remembering to drink plenty of water seems like a particularly easy task you can cross off your to-do list each day, for most people, it’s easier said than done. Things come up, we get busy, and before we realize it, the day has gotten away from us, and we’re no closer to our hydration goals than we were at the beginning of the day.

Fortunately, smart water bottles are here to make it much easier for us to stay on top of our hydration goals. But, just like every other kind of smart product on the market, there’s plenty of competition, and each model has its own unique set of features.

Finding the best smart water bottle for your needs doesn’t have to be difficult. Today, we’re going to take the guesswork out of choosing a smart water bottle, and cover some of the best options that are available today.

What is a Smart Water Bottle?

A smart water bottle is a reusable water bottle that uses cutting edge onboard technology to remind you to drink more water. The level of features differs widely depending on the model you’re looking at.

Some smart water bottles are simple, and their only function is to remind you to drink water throughout the day, either by lighting up or beeping. More advanced bottles can sync to fitness trackers, as well as Android or iOS devices to give you a complete picture of your drinking habits.

Other smart bottles have even more features. Believe it or not, it isn’t uncommon to find a smart water bottle with features such as a rechargeable power bank, Bluetooth speaker, safety lights and more.

Who Should Use a Smart Water Bottle?

Smart water bottles are ideal for anyone who’s looking to optimize their fitness level and the amount of water they’re drinking on a daily basis. For some people, they can easily manage those goals without the use of a fancy new bottle.

For the rest of us, who have trouble meeting our daily hydration goals, a smart water bottle could provide you with the help you need to stay on top of your hydration and fitness goals each day.

What to Look For in a Smart Water Bottle

With so many smart water bottles on the market, it’s no surprise that there are plenty of different features that differentiate them. You can easily narrow down your search for the best smart water bottle by evaluating which features you want, and which aren’t important to you. Here are some of the most popular features you’ll find in your search for the best smart water bottle.


Perhaps the most important feature you’ll want to consider is whether or not the water bottle has a smartphone or fitness tracker app you can make use of. While each app is different, they all work with your smart water bottle to provide you with a dynamic picture of how you can reach your hydration and fitness goals.

Digital Display

Some bottles feature a digital display which provides useful information like the time, the amount of water you’ve drunk that day, and even the temperature of the water. Typically, bottles that feature a digital display are not dishwasher safe and must be handled with care when hand washing.

Onboard Speaker

Believe it or not, some smart water bottles even come with their own dedicated Bluetooth speaker. Having an integrated speaker is a great way to ensure you’ll be able to listen to your favorite music, podcast or audiobook while you stay active.

USB Charging Capability

One of our favorite features available on some smart bottles is a USB power bank. The power bank will allow you to charge any USB powered device, like your phone, fitness tracker or wireless headphones while you’re on the go. USB power banks have become a popular accessory that many people never leave home without, and by integrating it into your water bottle, you’ll have peace of mind knowing you can always charge your most important devices while you’re on the go.

LED Lighting

Some smart water bottles feature LED lighting integrated into the bottle, which can be helpful for several reasons. Most bottles that feature LED lighting will light up when you need a reminder to drink more water, which is far less annoying than the loud chime reminders that some bottles have. It can also be useful to have a flashlight available if you run or train at night, or if you ever become lost or stranded somewhere.

Positive Effects of Drinking the Right Amount of Water

Everyone knows that staying hydrated is important, but you may be surprised at just how many different functions are affected by water. We would be here for hours if we covered all of the incredible benefits of drinking the right amount of water. But, here are some of the highlights you can expect to enjoy by staying properly hydrated.

Water’s Role in Physical Performance

Everyone is aware of the important water plays in maintaining physical performance, but do you know just how many functions of your body are affected when you’re dehydrated?

Losing as little as 2% of the water content in your body can play havoc with your body’s internal functions. Dehydration can affect our ability to control our body temperature, and increase oxidative stress during exercise. This leads to increased fatigue and decreased motivation, and it can make any physical activity seem far more difficult than it actually is.

Hydration and Brain Health

Beyond the role that water plays in regulating body temperature and maintaining peak performance during exercise, it’s good for your brain, too. Studies of both men and women after exercise revealed that a less than 2% fluid loss during exercise could impair our ability to concentrate, affect our mood, and increase feelings of anxiety.

Suffering from Headaches? Drink More Water

If you suffer from general headaches or painful migraines, they may be related to dehydration. Several studies have found that dehydration can cause headaches and migraines, and staying properly hydrated can help reduce the frequency and intensity of headaches.

Water May Help Relieve Constipation

If you’re having trouble taking regular bowel movements, upping the amount of water you drink may be a helpful way to reduce your symptoms. Not consuming enough water is a major risk factor for developing constipation.

Most treatment plans call for increasing the amount of fluid you’re drinking as a way to reduce or eliminate constipation. Carbonated water can be particularly helpful for those suffering from constipation, as well.

Water May Help Prevent the Formation of Kidney Stones

Kidney stones occur when there isn’t enough fluid in the urine to dilute substances such as calcium and urea, which can crystallize and form into clumps. Passing kidney stones can be exceptionally painful, and anyone who has ever suffered with them is likely to tell you that they’d do anything they could to prevent them from forming again.

Fortunately, it seems that water may be able to health. Preliminary research suggests that staying properly hydrated can help to prevent kidney stones from recurring in people who have previously dealt with this condition.

The idea behind the science is that staying properly hydrated increases the amount of fluid that is passed out in your urine each time you use the bathroom. The increased fluid can dilute substances like calcium and urea more effectively, which creates an environment where it’s much more difficult for kidney stones to form.

Suffering From Hangovers? Drink More Water!

Many of us look forward to going out for a few drinks from time to time, but no one looks forward to the hangover symptoms that are sure to follow the next day.

Alcohol is a diuretic, and diuretics make you lose water. After several drinks, your body will have significantly less water than it had before you started drinking, and this is a major contributor to the feeling of being hungover the day after a night out.

By simply drinking more water while you’re enjoying alcohol, you’ll be able to reduce the effects of the hangover. Try having a glass of water in between each alcoholic drink you consume, and be sure to finish the night off with a tall glass of water. There’s a good chance you’ll be pleasantly surprised when you awake the next morning, with a much less severe hangover than you would have otherwise.

Plus, supplementing your drinking with a glass of water in between each alcoholic drink is a great way to drink less and save money at the bar.

Water and Weight Loss

One of the most incredible benefits of water is the essential role it plays in weight loss. Drinking more water can increase feelings of fullness, and also up your metabolic rate, which translates to increased weight loss.

Certain studies have yielded incredibly promising results. A study of dieters revealed that those who drank just 17 ounces of water before meals lost an impressive 44% more weight than the control group. This is because their appetite was reduced slightly by the water they just drank, and the metabolic increase the water provided allowed them to burn more of the calories they ate during the meal.

The Fountain of Youth?

Beyond the incredible benefits we’ve already covered, water also plays a key role in maintaining a healthy complexion. Our skin is an organ that’s made up of billions of cells. These cells are primarily made of water.

Drinking an optimal amount of water helps to replace the water your skin loses throughout the day and helps to keep your skin well hydrated, which prevents the appearance of dry and flaky skin.

The best way to make sure your skin is getting enough water is by drinking 8, 8-ounce glasses of water per day. Applying a moisturizing cream is also a great way to increase the amount of water your skin can retain.

How to Keep Your Bottle Sanitary

While reusable water bottles like the smart bottles we’re discussing are a great way to keep yourself hydrated while cutting down on plastic waste, they can also act as a haven for all sorts of different germs and bacteria. Cleaning your bottle properly is important, and there are a few different ways you can go about it.

Dishwasher Method

If you’re lucky, you’ll be able to pop your bottle into the dishwasher, and clean it the same way you clean all your other dishes. Unfortunately, not all smart water bottles are dishwasher safe. Some have some delicate electronic components that can’t be subjected to the extreme heat and water that a dishwasher uses.

If you’re unable to use the dishwasher for your bottle, there are a few other ways you can get your bottle perfectly clean.

Dish Soap Method

Add a few drops of dish soap to your bottle and fill it about ¼ of the way with water. Place the cap back on the bottle and shake it vigorously. To get a truly deep clean, investing in a bottle brush can be helpful. If you don’t have a bottle brush, a toothbrush will do the trick, too.

Next, remove the cap from the bottle and scrub thoroughly with your toothbrush or bottle brush, taking extra care to clean the threads and mouthpiece of the bottle. Finally, rinse the bottle with cool water to get rid of all the excess soap, and allow it to air dry.

Vinegar Method

If you’re looking to achieve a truly deep clean, there’s an additional step you can use to supercharge your cleaning efforts. Once you’ve finished cleaning your bottle with the dish soap method, fill the bottle about ¼ of the way with white vinegar, and then fill the rest of the bottle with tap water and shake it vigorously. Then, just let the bottle sit overnight, dump it out in the morning and allow the bottle to air dry.

Water Bottle or Denture Tablets

As reusable water bottles have grown in popularity, a new product has hit the market which makes the bottles easier to clean: water bottle cleaning tablets. These effervescent tablets allow you to thoroughly and quickly clean your water bottle. If you’re unable to find tablets designed specifically for cleaning water bottles, denture cleaning tablets work equally as well.

Each brand has different instructions for use, so you’ll want to consult the directions on the package to ensure that you’re using the cleaner properly.

This Year’s Best Smart Water Bottles

Now that we’ve covered everything you’ll need to know about selecting and caring for your smart water bottle let’s take a closer look at some of the best models on the market right now.


Water Bottle


Editor's Pick

If you’re looking for a truly comprehensive solution, the STYR.24 3 in 1 may be a great choice for you. Not only does this set up include a smart water bottle, but it also includes other helpful fitness tools like a smart scale and fitness tracker.

The smart water bottle has a 20-ounce capacity and is made from durable Tritan BPA free plastic. It forgoes obnoxious ring reminders in favor of a water icon that appears on a small screen located on the cap of the bottle which reminds you when it’s time to drink. The data from the water bottle automatically syncs to the STYR.24 app, and it automatically adjusts your daily needs based on your activity level.

[expand title="Expand For More"]


The wireless smart scale allows you to track your weight, BMI, body water content, bone mass density and more. Just like the water bottle, the data from the scale syncs automatically to the app.

Rounding out this offering is a fitness tracker, which measures important metrics like steps taken, calories burned, distance traveled, daily time spent active and more. The tracker can be worn on your wrist or your belt. Just like the smart scale and water bottle, the information from the tracker syncs to the app.

The folks at STYR Labs thought of everything when it comes to the design of their application. The app is available for Android and iOS devices, and it can also sync with Fitbit and other fitness trackers as well. The app is well designed and easy to use, even for the technologically challenged.

The STYR.24 3 in 1 kit comes in a bit more expensive than most of the competition at around $100. But, compared to the competition they’re delivering a much more comprehensive fitness and hydration solution. For people who already have a scale and fitness tracker they like, this kit may not be the best option. But for people looking for a comprehensive solution, the STYR.24 may be a perfect match.

Best Value

If the idea of a smart water bottle sounds great to you, but you’re reluctant to shell out 50 dollars or more to purchase one, then the Garne-T Smart Cup may be perfect for you. This budget-priced smart water bottle provides the most important functionality you need, without the more expensive bells and whistles.

The Garne-T does manage to pack in some intuitive features despite its low price. Touch the bottle, or clap in its vicinity, and it will light up and display a digital readout of your beverage’s temperature. This feature is especially useful if you wake up in the middle of the night for a drink, as you can clap your hands to learn where your cup is located, instead of fumbling around for (and potentially spilling) your glass.

[expand title="Expand For More"]


Every two hours, the bottle’s light flashes on and off to remind you that it’s time for a drink, which helps you stay on top of your hydration goals.

Unlike most smart water bottles, which need to be recharged regularly, this model runs off of 2 AAA batteries. Unfortunately, this cup doesn’t come with a dedicated application to help you manage your hydration. But, it does manage to provide the basic functionality you’ll need from a smart water bottle at a low price.

If you’re looking for the best water bottle to use with your Fitbit, the Ozmo smart bottle is one to look into more closely. This bottle plays well with all fitness trackers, including Fitbit, Apple Health, and Garmin products.

In addition to its two-way integration with Fitbit, Ozmo also has an app that can help you track your progress to your daily goal. The app works with every popular Android and iOS smartphone.

[expand title="Expand For More"]


There’s also LED lighting on the cup which allows you to track your progress at a glance. When connected to a fitness tracker like the Fitbit, the Ozmo will adjust your daily hydration goals based on your level of activity to provide you with a custom-tailored solution for your hydration needs.

Unlike other smart bottles, the Ozmo is equally at home with hot liquids as it is with cold ones, so if you’re interested in tracking your coffee consumption, the Ozmo can help with that as well.

When it’s time for more water, the Ozmo bottle vibrates to alert you, which is much nicer than the loud beeping that some smart bottles rely on. It’s 16-ounce capacity is large enough that you won’t have to worry about constantly refilling the bottle.

As for construction, the Ozmo is made from thick double walled BPA-free plastic, which helps to keep your beverages cool (or hot). It’s one of the more rugged bottles on the market, making it a great option for anyone who is concerned with breaking the bottle as they go about their daily activities.

If your biggest concern is finding the best water bottle to sync with your iPhone, the h2o Pal is worth checking out. Compared to other bottles, this one features a high-end look and feel that some people are sure to appreciate.

The h2o Pal features high-quality glass construction and a stainless-steel lid. Silicon bands are strategically placed to add grip and protect the bottle in the event of a fall. At the bottom of the bottle, the h2o Pal hardware tracks your water intake and monitors your daily goal.

[expand title="Expand For More"]


The h2o Pal then syncs the data it receives with your iOS devices, such as an iPhone, iPad, or Apple Watch. The bottle delivers friendly reminders throughout the day to your iOS device whenever it’s time to drink more water.

This bottle also syncs with Fitbit, and an Android app is currently in beta development. Buyer beware, the Android app is still very buggy, so this may not be the best choice for you if you’re looking for an Android compatible device.

While this bottle certainly offers a high end feel, it’s slightly less practical than some other models at times. For example, it doesn’t fit in a car cup holder, and it’s heavy glass construction doesn’t lend itself to use when biking, hiking or running.

Hidrate made waves in the smart water industry with the original Spark water bottle, and they refined the design based on customer feedback before releasing the Spark 2.0. This new version of the popular Spark smart water bottle improves upon the features and connectivity of the original, making it one of the best water bottles on the market.

The Spark 2.0 plays well with virtually any device. It integrates with Android, iOS, Fitbit, MyFitnessPal, and other daily fitness trackers, and it also has its own dedicated app. A removable sensor in the water bottle tracks the amount of water you consume and monitors progress towards your daily goal. 

[expand title="Expand For More"]


When it’s time to drink more water, the bottle produces a cool glowing effect; our favorite alert system of any bottle we tried. The bottle is powered by a long-lasting battery in the sensor, and Hidrate provides an additional two replacement batteries with each bottle.

The Spark 2.0 is also one of the largest and most practical smart water bottles. It has a 24-ounce capacity, and the cap and bottle are both dishwasher safe. Despite its larger size, this is also one of the few bottles that fit comfortably inside car cup holders.The removable sensor can be washed by hand. As you’d imagine, the Spark 2.0 is entirely BPA free.

The Hydra Smart Bottle is one of the most interesting bottles on the market. Unfortunately, it doesn’t offer any hydration tracking. However, the bottle is certainly smart for other reasons, and it may be worth a closer look, especially if you’re an outdoors enthusiast.

At its heart, the Hydra bottle is a 20 ounce, BPA free water bottle. Beyond that, things get a little crazy. The bottle is also a five-watt Bluetooth speaker with a 3.5mm jack and a 4000mAh power bank, a lantern, and a lighting system. 

[expand title="Expand For More"]


The speaker also transmits FM radio, and it has a microphone, so you’re able to take calls on speakerphone through the speaker. It also includes a carabiner clip with bottle opener, and it features an app which allows you to control the different lighting functions, among other cool features.

So, you won’t receive any fitness technology, and this bottle won’t necessarily help you meet your hydration goals. But, this bottle is still worth a closer look for people who love the outdoors, as well as anyone looking for a unique gift.

Our Overall Winner

One thing that we’ve realized through trying different smart bottles is that different bottles are better suited to different tasks. Some perform better with certain devices, while others generally perform well with any device.

However, there is one bottle in our roundup that performs so well in virtually every category, that we’ve given it the distinction of our overall winner.

The Spark 2.0 from Hidrate checks virtually every box for what you’d want out of a smart water bottle. It syncs with the most popular devices and works well with each one. It also has a smart, useful alert system and a sleek look that’s less bulky than many other bottles.

The Spark is also our favorite bottle for workouts, and it’s easy to transport in a car cup holder, in your hand, or in your bag. Add to that the fact that almost the entire bottle is dishwasher safe and you have a smart water bottle that makes a solid choice for anyone looking to take control of their hydration needs.
