HI Georgia,
Welcome here and awesome for losing weight. I also like to do 10,000 - 15,000 steps a day. Walk with the app if you would like, walk fast thought and work yourself up to a jog. You can do it..
So proud of you and please keep us posted....
YAY!
Fixed this problem, i was being savvy with my phone and turning off notifications, background apps ect to save battery on iPhone.... Must hav accidentally turned off notifications! Whoops x
