Screen locked, phone in the pocket
Tracking and cheers keep working with the screen locked and the app in the background. That's the normal way to race with Cheerlify.
What must stay on:
On iPhone, with the screen locked, positions are sent in batches about every minute to save battery. So a cheer sent "right now" can arrive up to about a minute later.
If the phone sends nothing for 6 minutes, we send you a notification. Open Cheerlify and it continues where it left off.
