1. Does not collect user data. 2. Can be used without a subscription or purchase. 3. Has you complete challenges in order to shut off alarm. CluckClock has all of this. This app is very minimal but has unique features and is beautifully designed. For me it’s important to have wake up challenges with my alarm otherwise I will shut it off and immediately fall asleep again. This app implements these challenges by either shaking your phone X times or playing a small game to collect worms for your chicken. The feature of having a chicken is amazing, it really keeps you accountable and helps to keep track of your wake-up habits. If you miss your alarm too many times your chicken will die of starvation and go to your graveyard, where you can view its stats. The chickens are so cute and customizable and so funny. This app has NO ads, NO subscription, and can be used fully without any purchases. Most importantly, there is no data collected and the privacy policy is very straight forward. It is very difficult to find an alarm clock on the App Store right now without excessive user data collection or ads. They almost all have data linked to the user for tracking. Why does an alarm clock need your contact info, your location, your purchase history, etc. I spent almost an hour scrolling until I found this and I haven’t looked back.
