A $20 Asian FitBit knock off. The app it works with is VeryFit Pro; syncs via bluetooth. You can export to Google Fit but I don't bother. It keeps history and does enough reporting for me to get a good idea of how much I am doing. It even has the heart beat monitor, phone sync to show calls and texts, inactivity alarm, etc, but I just use it to track steps and see what time it is...
