When people start researching activity trackers, many wonder if they should buy a water resistant fitness tracker. Considering you’ll be buying a wristband that you’ll wear 24/7, it’s a good idea to pay attention to this feature. The kind of exercise and other activities you do on a daily basis will determine if you need a water resistant fitness band.
Most activity trackers and fitness trackers on the market these days are water resistant. That means you can sweat on them and wear them in the rain without issue. Some you can even shower or wash your hands while wearing them and the tracker will be just fine.
If you’re a swimmer or plan to wear your fitness tracker while you surf or do other water sports, you don’t want a water resistant activity tracker. Instead you need a waterproof fitness band for swimming or a waterproof fitness watch. Many people don’t realize there is a difference between water resistant and waterproof trackers, and you need to pay attention to this when you decide what fitness tracker or pedometer to buy. (Read more about the difference between water resistant and waterproof activity trackers.)
If you’re just looking for a fitness tracker you can wear without shorting it out from a little moisture, you can save money and have more options to find the right tracker for you. Here are some water resistant trackers to consider:
Water Resistant Fitness Trackers
Nike+ GPS Sportwatch
Using TomTom GPS, the Nike+ GPS Sportwatch is an awesome tracker for runners. It combines the GPS tracking with an optional shoe sensor for one of the most accurate step counts runners can find with a wristband tracker.
It’s a water resistant fitness tracker so you’re fine if you go for a run in the rain, but it’s not waterproof so don’t jump in the pool with it.
Fitbit Flex This comfortable and easy to wear activity tracker sacrifices the LCD display of more gaudy pedometer-like bands for LED lights that show you your progress toward the day’s step goals. You have the Fitbit app to easily track your steps, activity, and sleep on your smartphone or tablet.
The big difference with the Flex is that the band is fully customizable with a ton of different bands to personalize your Fitbit or match any occasion. Track your activity without sacrificing on style. It’s water-resistant, so you don’t have to worry about sweat or rain damaging your tracker, but don’t wear it in the shower or the pool!
Available colors: black, slate, tangerine, blue, pink, red, teal
Tracks: steps, distance, calories burned, active minutes, sleep quality, and quantity
Notable features: silent alarm, swappable wristband, automatic sleep monitoring, 5-day rechargeable battery, syncs wirelessly to computers and smartphones, water resistant
If you want to hit the pool with a new Fitbit, the Charge is a great option with its water resistance up to 50 meters. You’re safe at the beach, in the showers, or just taking a run in the rain. It also has built-in GPS tracking, so it’s great for runners to track their training. Active folks who like to vary their workouts will appreciate that the band tracks
swimming, biking, and weights as well as gym workouts. SmartTrack automatically recognizes the activity and records the workout for you. The OLED tap display makes it easy to see real-time stats while you’re exercising and get your workout results without syncing to your smartphone.
Other great features include tracking floors climbed, on wrist payments through Fitbit pay, and the ability to store and play music from Spotify, Deezer, or Pandora.
The Charge also has 24/7 continuous heart rate monitoring. It tracks your heart rate throughout the day to track your calories burned and also gives you a Cardio Fitness Score to help you improve your fitness level over time. Get even more info on your heart health with the on wrist ECG app. Thanks to the EDA scan app, your exercise tracker will also notice when your heart rate is elevated due to stress and lead you through a guided breathing exercise to help calm your mind and body.
In addition to all those fabulous features, the Fitbit Charge has many of the features longtime Fitbit users love like move reminders, smartphone notifications, wireless syncing to smartphones or computers, and interchangeable bands.
Available colors: Black/graphite stainless steel, lunar white/soft gold stainless steel, steel blue, platinum stainless steel (plus endless band options)
Tracks: steps, heart rate, GPS, distance, calories burned, active minutes, floors climbed, stationary time, auto sleep tracking
Notable features: interchangeable bands, PurePulse wrist-based heart rate, Cardio Fitness Score, silent alarms & auto sleep tracking, 7-day battery life, multi-sport modes, move reminders, SmartTrack auto activity tracking, OLED touchscreen with on-screen stats, guided breathing prompts based on heart rate, smartphone notifications, swimproof

Garmin Vivofit Fitness Band
The Garmin Vivofit Fitness Band is a fitness tracker that is very popular among runners. It’s water resistant and boasts a battery life of one-year, so this is a low maintenance tracker. This fitness band features a digital display of your step count and the current time. Use the personalized daily goals and the “Time to Move” reminders to live a healthier life and reach your fitness goals.
It can connect to an optional heart rate monitor chest strap to capture your heart rate, which automatically syncs with your smartphone.
The first Vivofit is only a water resistant fitness tracker. If you’re looking for a waterproof version, check out the Garmin Vivofit 2 activity tracker, which is perfect for swimmers.
Available colors: black, blue, purple, slate, green
Tracks: steps, calories, sleep
Notable features: Year-long battery life, water-resistant, displays stats and time on band, Move Bar records idle time and inspires you to move, sets daily goals, optional heart rate strap
For most people, waterproof activity trackers don’t matter because their main form of exercise is running or going to the gym. But if you enjoy aquatic activities like swimming, like to vary up your workout, or worry about accidentally killing your fitness tracker by dropping it in the sink or accidentally wearing it in the shower, you may want to consider how waterproof the activity tracker is.
Generally, fitness bands fall into one of three categories: lightly water resistant (able to withstand sweat, splash, and rain), highly water resistant (can be washed in the sink or worn in the shower), and fully waterproof (safe for swimming or any other water related activities).
Does it matter if I buy a water resistant or waterproof fitness tracker?
Whether you buy a waterproof fitness tracker really depends on your lifestyle and what types of exercise you do. The average person may not need to worry about this feature. But if you are concerned about how water will affect a fitness tracker you plan on wearing 24/7, it’s a feature you should pay attention to as you research the best fitness band for you.
You may find it surprising that these tiny little bracelets, with advanced electrical and computer components, can actually be pretty sensitive to water. Unless the band is completely sealed off, they can be damaged easily.
For example, none of the Fitbit activity trackers are waterproof. They are water resistant, which means they are rainproof and splash proof, and no matter how sweaty you get during your workout, you will not harm your fitness band. But since Fitbits are not waterproof, you cannot shower in them or swim with them.
Some fitness trackers are more water resistant than others, meaning you can shower in them or get them wet when you’re washing your hands or washing the dishes, but they shouldn’t be submerged in water for swimming. Some trackers are water resistant enough to wear in the shower, but should not be submerged in liquids, so they can’t be worn for surfing or swimming.
If swimming is your main form of exercise, you need to find a waterproof activity band or waterproof fitness watch to track your exercise (and a lot of them have cool features specific to swimming, like counting laps).
Should I buy a water resistant or waterproof fitness tracker?
If you’re a swimmer, get a waterproof tracker. If you’re a forgetful person who may not remember to remove your fitness tracker before you shower, get a more water-resistant band. For everyone else, get whatever model you want.
Here are a few fitness trackers you may want to consider in each category:
Sweat Proof and Splash Proof Fitness Band
Fitbit Charge (Check reviews and prices) The Fitbit Charge combines the best features from the Fitbit One with the wristband format of the Fitbit Flex. The same great sleep tracking and silent alarm is still available, but it also includes an OLED screen that includes step count, the current time, and call notifications. When paired with your smartphone, it will display on your wrist who is calling so you don’t have to dig your phone out of your pocket or purse if you don’t want to answer.
It’s advertised as water-resistant, but they really just mean sweat proof and splash proof, so don’t take your Fitbit in the shower or the pool unless you want to brick it.
Available colors: black, slate
Tracks: steps, distance, calories burned, stairs climbed, active minutes, sleep quality and quantity
Notable features: OLED display for steps and time, call notifications, 7 to 10-day rechargeable battery, automatic sleep monitoring, silent alarm, syncs wirelessly to computers and smartphones, water resistant
Water Resistant Activity Tracker You Can Shower With
Jawbone UP3 Activity, Heart, and Sleep Tracker
The Jawbone UP3 includes all the basic features of step counting, food and calorie tracking, and multiple exercise modes. It’s also splash and showerproof, so if you forget to take it off when you shower or get caught in a thunderstorm on your afternoon run, you know your UP3 is safe.
It also features Advanced Sleep tracking. Using bioimpedance sensors, the UP3 uses your heart rate to track your sleep phases, including Wake, REM, Light Sleep, and Deep Sleep. This makes the Smart Alarm even more accurate.
If you’re looking for heart rate monitoring, UP3 includes that as well. The same bioimpedance sensors track your resting heart rate and your passive heart rate to give a complete picture of your heart health.
Available colors: black twist, black/gold twist, indigo twist, ruby cross, sand twist, silver cross, teal cross, twilight cross
Notable features: Smart Coach, sleep tracking, Smart Alarm, Idle Alert (move alerts), automatic sleep detection and advanced sleep tracking, splash-proof and waterproof, LED indicator (notification and status), battery lasts up to 7 days, wireless syncing
Waterproof Fitness Tracker
Garmin Vivosmart 4 Fitness Band
The Garmin Vivosmart is the Vivofit’s cousin, only it features a sleeker, higher end design with a more minimalist display integrated into the band itself. It measures calories burned, steps taken, distance, gives move reminders, and has great battery life. With a touchscreen display and integration with your smartphone, it’s a fitness tracker worth considering if you’re looking for a waterproof option that you can shower and swim with.
Available colors: black, blue, berry, slate, green
Tracks: steps, calories, distances, sleep
Notable features: Waterproof 5 ATM, touchscreen, smart notifications (calls, texts, emails), vibration alerts and move reminders, auto-syncs to mobile devices, time display, alarm clock
Remember: You shouldn’t wear your fitness band 24/7. Your skin needs a chance to breathe and reset. Even if your tracker is waterproof, I would recommend taking it off when you shower so you can fully wash your wrist and arm and give it a little break.

It’s no surprise that Fitbit has released another smartwatch to compete with the others on the market. They’ve taken some cues from Apple’s designs making a lighter, sleeker smartwatch centered around fitness and health tracking with interchangeable bands and customizable displays. The latest version now has built in GPS, great for runners. And the feature you may be most excited about: it’s swimproof! That’s right, if you’re a swimmer you can use your Versa smartwatch in and out of the pool. With the touchscreen, you can track all your stats on your wrist, plus you still have access to the Fitbit smartphone app for all the indepth tracking and stats you need. The Versa also provides personal coaching to keep you moving and help you meet daily goals.
Since fitness is our main focus here, let’s talk about the features that make the Versa unique from the rest of the Fitbit line-up. With over 20 built-in exercise modes, the Versa can give you real-time stats for activities like swimming and running. If you need inspiration, you can follow the dynamic on-screen workouts which coach you through every move. If you’re a runner or a cyclist, the Versa can sync with GPS from your phone to provide you pace and distance stats.
If meditation and relieving stress is important to you, the Versa has guided breathing sessions, which uses your heart rate to give you personalized instructions. For women, it has built in health tracking so you can track your cycle and even get reminders before your period starts.
What about the fun features you want a smartwatch to have? Music is one of the most important parts of my workouts and I love that you can store 300 songs directly on the Versa and play them with Bluetooth headphones. Fitbit has also brought features like call, calendar, text, and app alerts to your wrist. Plus, it features Fitbit Pay on their special editions so you can pay with your watch. With a six day battery life, it has many other smartwatches beat. The Versa is a fantastic smartwatch and is really giving the Apple Watch some competition.

Some of the classic Fitbits that have been fan favorites have since been “retired” for new models. A lot of the excess stock is still available to buy from online retailers like Amazon. Check out our reviews of these retired models below.
Fitbit Zip
The Zip was the budget Fitbit for many years. It’s the simplest to use and a great option for anyone looking for a cheap activity tracker or a more basic pedometer type tracker.
The LCD display conveniently shows the current day’s step count and also the time. When you reach your step goal for the day it buzzes in congratulation. Sync it to the free Fitbit app and track your daily stats to improve your activity over time.
This makes a great gift for older parents who aren’t very tech-savvy but are looking for an easy way to track their activity and steps over time. Since it has the option to sync to a computer, it’s also great for people who don’t use smartphones.

If you’d rather wear your fitness tracker on your wrist than on a clip, the Fitbit Flex 2 may be the tracker for you. This comfortable and easy to wear activity tracker sacrifices the LCD display for LED lights that show you your progress toward the day’s step goals. But you still have the Fitbit app to easily track your steps, activity, and sleep on your smartphone or tablet. This is a recent update to the original Fitbit Flex that combines the features users loved about the original with some new functionality.
The big difference with the Flex 2 is a brand new ultra-slim tracker design that is fully customizable with a ton of different bands to personalize your Fitbit or match any occasion. This includes bracelets and necklaces that look like fashionable jewelry instead of utilitarian trackers. Track your activity without sacrificing on style.
I’m sure you’re wondering, what’s new with the Fitbit Flex 2? Well, the big thing is: this activity tracker is now waterproof–or as they call it “swimproof.” You can finally wear your Fitbit in the shower or while swimming in the ocean or pool without destroying your tracker. I have a feeling this one is going to become very popular with swimmers.
It also features SmartTrack, which automatically recognizes certain activities (including swimming) and tracks your workout for you automatically. There are also smartphone notifications in addition to the silent alarms. All these features come without sacrificing the battery life of the original model.

Alta also has move reminders, giving you a gentle buzz when you’ve been sitting too long so you can take a quick walk.
