Cannot get the app to work correctly, tried a different one and it cannot find the device, however it seems to keep steps fine and records my sleep.

I like it but just doesn't stay charged for very long.

I gave 3 for gifts and all are very pleased.

This is a useless tracker. App is in Mandarin and there is no support for technical problems. After daylight savings time change, the device would not reset or resync. Data was not accurate as a tracker. Nice design but the device and app were ineffective. Now past the return policy which now makes this landfill material - a total waste and loss.

This is nothing but a glorified pedometer. It does not track heart rate, and it only counts calories based upon your steps. Terribly inaccurate. Don't waste your money.

Wouldn't work with app. I am returning it.

Stopped working after a few weeks. Avoid!

Not accurate. Cheap. Wish i didn't buy.
