Questions

Can Kro see what I do in my apps?

No. Apple's Screen Time system does the locking. Kro never sees what you look at inside your apps.

Does the camera record me?

No. Reps are counted live on your phone. Nothing is recorded unless you choose to send a duel video to friends.

What exercises can I do?

Six: push-ups, squats, sit-ups, jumping jacks, a plank and a squat hold. Pick whichever suits you that day. You also get three passes a month for real emergencies.

How much is it?

Free to download. Kro Pro is a subscription you can cancel any time in your Apple ID settings, with a money-back guarantee.

Your apps are waiting.
