Cola in Freezer is a timer - it can help you remember cola (or any other non-caffeine drink - drink responsibly before bedtime!) that you've put in the freezer by reminding (annoying) you of it every 5 minutes with a bottle-open-hisisch-noise.
The app also works really well in the background with Android 11 and above. So some things DO get better with age!
Did you ever have a burst cola bottle in your freezer? This app can help you!
