FAQ

How does the app count? Lay your phone flat under your head or chest and hold still for a moment. A rep counts after you lower yourself and return to the top. On Android and iPhones without Face ID, place the phone under your face. Android counts changes in face size rather than measuring distance in metres.

How do I invite friends? In the app, go to “Group”, tap “Invite friends” and share the link.

Delete your Liegestütze Challenge account

In the app, open Profile → Delete account and confirm. This deletes your account, training data, profile photo, group memberships and sign-in account.

Without the app, request the same deletion by emailing josua.sievers@gmail.com from the email address used for your account. State that you want your Liegestütze Challenge account and its associated data deleted. We may verify account ownership before processing the request. Deleted data may remain in backups until they are overwritten.
