I've been looking for a task-based alarm app (i.e. solve math problems before you can disable it) that doesn't require any more access than knowing whether or not I am currently in a call (to reduce or mute the alarm). So far, all the apps I have found require some combination of the following priveleges:

  - Identity
  - Wi-fi
  - Location
  - Photos/Media/Files
  - Camera/Microphone
  - Device & app history
  - In-app purchases
  - Device ID & call info

Only the last is required (and only the "call info" part). I can't imagine anyone who would ever want an alarm app to track their location or have access to their identity information, but perhaps such people exist.

I'd prefer no ads, so I'm willing to pay for a no-ads version. But ONLY if the app is not a power grab by the developer so that any conceivable monetization strategy is available to them in the future. If I can't find such an app I'll just have to use the built in Android alarm (which isn't task-based, sadly).
