Life changerArvosana 5/5
Bought it a week ago, I've been able to walk from 6 - 10 km in a work day (time that I suppose to spend sitting). Lost around 3 kilos already.
The app has a bad review on PlayStore, but it is actually pretty good, it registers the amount I've walked (steps - time - distance), and allows me to set a daily target.
I'm pretty happy and recommend it to everyone who work sitting for long hours.
