Apple needs to watch out, because Fitbit is coming for their smartwatch crown. Fitbit’s Ionic Smartwatch is a serious competitor to other high-end smartwatches for sports enthusiasts and fitness minded users. They’ve pack in a ton of features everyone will love.
Let’s start with the ways the Ionic will help you stay fit and active. Fitbit coach gives you dynamic personal workouts to keep you motivated at the gym or at home. This is an all-around health tracker. It includes all of the features you expect in an activity tracker, like step counting, setting goals, and workout tracking. In addition, it has continuous heart rate monitoring to give you real-time info as well as more accurate sleep data. The built-in Fitbit Coach is perfect to guide you through a personalized workout to meet your fitness goals. This is great for fitness enthusiasts who like to work out in many different ways.

If you’re trying to decide between the Apple Watch and the Ionic, here are the big points to consider. Ionic has a better battery life (4 days vs 18 hours) and offers sleep tracking.

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. 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 15 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.

Retired Fitbit Trackers
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.
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.

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.

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.

There’s also smartphone notifications in addition to the silent alarms. All these features come without sacrificing the battery life of the original model.
