Packed with a ton of software and hardware features, the Fitbit Ionic is the most financially friendly watch of the bunch. Taking a step further than just fitness tracking, the Fitbit Ionic packs in workout apps like running, biking, and swimming.

I can sync my stats to my RunningAHEAD app with my Bluetooth-enabled smart phone. While it does not show the time of day on its own, it is connected with a watch face app which shows day of week and date.

One of the cool features that I really appreciate is the ability to quickly change the date or time without having to go through different menus.

What's the best fitbit for swimming?

For swimmers, there are two main types of waterproof fitness trackers: those designed for use specifically in the water, and those that are water-resistant. Many people interested in fitness trackers tend to think that waterproof means they can take the tracker into the pool or other water activities. This is definitely not the case.

For swimmers, it is more important to dive a little deeper into the specifications of the fitness trackers.

Water-resistant trackers are indeed intended to be used in water, but it is important to note that this does not necessarily mean you can take it into the pool or ocean. However, it is possible to get a waterproof fitness tracker, but this is generally more expensive than the water-resistant models.

No matter which iteration of the fitness tracker you choose, any of them can withstand a reasonable amount of water to track your fitness activities.


After careful research and consideration, we chose these water-friendly fitness trackers as the best for those who are extremely active or have an intense exercise regime. Depending on the watch, you’ll get features like swimming, built-in GPS, heart-rate tracking, sleep tracking, and more. Some of them aren’t for the casual exerciser and are geared more towards runners and bikers and the like.
