Pro Long battery life
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 on it and line up the pins.
Pro MiCoach Train and Run app
You can set weekly goals and training plans through the 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.
Pro Easy navigation
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.
Pro Colored LEDs show intensity
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.
Con Not for casual use
The Adidas Fit Smart lacks any daily activity tracking. Instead it focus is more on workout/running.
Con Ugly design
While functional, the Fit Smart won't be winning any design awards. It isn't something that you'd really want to wear everyday to work.
Con No GPS
GPS is much more accurate for distance tracking than the accelerometer which the Adidas Fit Smart uses.
