My favorite feature: The Team-Mode, where you and friends can battle it out. Great when hanging around with a bigger group of friends, you can split up for a set amount of time and see, who gets the most points.
I am not affiliated with the app, but really enjoy it and thought that you guys might like it as well. Have a nice day!
Yea, depending on your area, there will be too many questions. Sometimes even walkingspeed is too fast, as there are a lot of missing data sometimes
