Honestly, this app has brought me nothing but frustration and I'd give it 0 stars. I have walked 20+ km that it lost in the last several weeks. It keeps failing to log my work outs by freezing in the finishing page with a circle of death. I've come to hate the app that promised fun walking together and it won't pull walked data from other apps that show I did the app. And if I log my work out manually, they don't count towards my challenges. This app is buggy and I wouldnt recommend it.
