## What is MathBell?

MathBell is a math alarm clock. Your alarm rings through Silent and Focus, and it only stops when you solve a short puzzle.

Solve to stop
Each alarm asks for a few quick sums before it goes quiet. Pick the puzzle type and difficulty: arithmetic, running totals, missing numbers and more.

Follow-ups until you solve it
If you dismiss the alarm without solving, MathBell rings again every minute until the puzzle is solved. Snooze is limited, so you cannot keep putting it off.

Built for mornings
- Alarms ring through Silent and Focus with the system alarm sound
- Weekday, weekend and custom repeats
- Choose from six alarm sounds
- Home Screen and Lock Screen widgets that show your next alarm
- A wake-up check a few minutes after you solve, so you know you are really up

Made for iPhone Duo
MathBell works in portrait and landscape on both displays, so you can set alarms on the outer display or spread out on the inner one.

Free and Pro
Start with 3 alarms for free. MathBell Pro unlocks unlimited alarms, every puzzle type and difficulty, all sounds and widget styles. Choose a yearly or monthly subscription, or pay once for lifetime access. Subscriptions renew automatically until cancelled; manage them in Settings.

No account, no ads, no tracking. MathBell stores your alarms on your device.
