I'm opening up a testflight link for Snitch! The concept is - you pick your app and website activities, set a time limit then choose a friend or family member to snitch yourself to when you go over the limit. The tracking is logged from the iOS screen time APIs which is all secured on your own device. I just wait for the monitor to tell me you went over the limit and send a push notification to you and a text to your snitch buddy.

Thanks for helping test, and hope it helps you control your screen time usage.
