Captcha

1. What it does

Gives you a task to solve in order to dismiss the alarm.

CAPTCHAs make sure you wake on time and won’t be late for your daily duties. CAPTCHAs prevent any unintentional alarm dismiss.

2. Where to find it

Note CAPTCHA can also be configured in Alarm-specific settings. You can override your default CAPTCHA settings on each alarm and use a more difficult CAPTCHA on special occasions (e.g. exams) or an easier CAPTCHA on the weekends.

3. Options

Default CAPTCHA

CAPTCHA for all alarms (that are not overridden by Alarm-specific settings)
CAPTCHA Difficulty

Sets CAPTCHA difficulty. How is difficulty used depends on each CAPTCHA. E.g. Math CAPTCHA requires you to do more equations with larger numbers on higher difficulty.
Preview

See the selected CAPTCHA in action.

Warning We strongly recommend to test each CAPTCHA with the Preview feature and use Settings before it is used in the morning - that could bring unwanted surprises.
Settings

Some CAPTCHAs have addition settings, e.g.:

  • Editing, adding, and deleting QR codes and NFC tags

  • Selecting tasks for MultiCaptcha

  • Choosing your mantra for Mirror Text CAPTCHA

Alarm volume in CAPTCHA

To get more time, tap on the + icon in the upper right corner
Prevent escaping CAPTCHA

Prevents avoiding solving the CAPTCHA. Especially from force closing or uninstalling the app during the task.

I cannot uninstall the app

You have probably activated Prevent escaping CAPTCHA option.

This option registers the app as a device administrator in order to block turning off the phone when an alarm rings.

  • Go to System settings → Location and Security → Device Administrator and deselect the admin which you want to uninstall.

  • or disable Prevent escaping Captcha in Settings → Captcha: Stop oversleeping! → Prevent escaping Captcha (might be hidden under Advanced menu)

Now uninstall the application. If it still says you need to deactivate the application before uninstalling, you may need to Force Stop the application before uninstalling.
