Adidas Fit Smart vs Xiaomi Mi Band 2

Wearing it continuously, you can expect around 5 days of use. If you only wear it during workouts, it will last closer to a full week. The charger is proprietary, and you simply place the Fit Smart fitness tracker on it and line up the pins.

You can set weekly goals and training plans through the fitness tracker's app. One downfall is that if you have a training plan set in the app, you can't also have weekly goals. Once you have a plan selected, it will sync with your phone so you don't forget when you wanted to workout.

You can also access previous workouts and achievements from the app, along with estimated times for 5k, 10k, half, and full marathon races based on your past running performances.

There are 3 buttons on-board. The first toggles between battery status, time, and the different training modes. The other two take you through MiCoach and free training modes. These buttons are easy to find, even with gloves on.

During workouts, the LED lights on the side change color to show how intense your workout is. White (74bpm) is none-light activity, Blue is warm up/cool down, green is calorie burn and boost endurance, yellow is intense training and muscle burn, red (182bpm) is short power bursts to develop strength and speed.

If you have a MiCouch workout selected, on-screen you will see an up or down arrow indicating whether you should pick up the pace or slack it off.

It's a great option if you're not looking to invest a lot of money but still want a tracker with a decent set of features.

You get step tracking, sleep tracking, vibrate notifications, call notifications, clock, alarm, custom actions (via third party apps), heart rate reader (albeit not the most precise one) for the fraction of the cost of the competitors.
