## What is Demon alarm?

Tired of snoozing your alarm and going back to sleep? Demon Alarm forces you to solve math problems before it stops — no shortcuts, no snooze button.

Choose your difficulty from basic arithmetic to calculus-level problems. The harder the math, the more awake you'll be by the time you're done.

Features:
• Math challenge required to dismiss
• Multiple difficulty levels
• Build in sound packs including:
• Insults
• Screams
• Weird and embarrassing sounds
• Import your own alarm sounds

The app is free to use, but with limited features. Free users will be forced to the hardest math difficulty and locked to the built-in sound pack.
