About

WakeProof Alarm Clock

Features
Read full description

WakeProof is a proof-based alarm clock for people who struggle to get out of bed. You can explore WakeProof for free. Setting and enabling alarms requires a WakeProof Premium subscription. Instead of tapping dismiss and falling back asleep, WakeProof asks you to complete proof missions before the alarm stops. Use a QR station in the bathroom, step goals, math problems, shake tasks, or a wake check after dismissal. Key features: - Create alarms with repeat days, labels, sounds, snooze rules, and vibration. - Add proof missions that are designed to get you moving. - Use QR proof stations stored locally on your device. - Track streaks, missed alarms, emergency stops, and wake-check results. - Check alarm readiness before bedtime. - No account required. WakeProof is built for heavy sleepers, early mornings, school, work, routines, and anyone who needs more than a basic alarm clock. Note: iOS does not allow third-party apps to register the same kind of system alarm as Apple’s Clock app. WakeProof uses local notifications and in-app checks where available, and includes an Alarm Readiness screen to help you prepare your device settings. WakeProof Premium is an auto-renewable subscription purchased in the app. Prices and plans are shown before purchase, and new subscribers may get a free trial where offered. Payment is charged to your Apple Account. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings. Privacy Policy and Terms of Use: https://github.com/tarikyesilcimenn/Wake-Proof/blob/main/POLICY.md
