Used to be really good. Used it all the time for building up my Vitality insurance points and seemed accurate. In recent weeks, however, it stops picking up steps. Walk the dog in the morning....7000 steps. Walk the dog again in the evening. Still 7000 steps. Went for a walk the other day....zero steps. So the app doesnt record my evening steps at all or sometines none all day. My OnePlus steps app is recording all steps, so its not the phone. Happened 3 or 4 times in recent weeks.
