Useless. Was very good at beginning. Started to use it 2 or 3 years ago and was good with steps counting even if phone was in my bag. Each update has made it more difficult to have an accurate step count to the point that if the phone is not in my back pocket half to a third of steps only are counted! Also today tried to donate and that as also be made a lenghtly process as cannot enter the amount but have tp pressthe + button. Am going to persevere to get my account to 0 and get rid of this app
