About this app

Alarmy is an alarm clock that actually gets you up — and it works entirely offline.

Set a Simple alarm when a tone is enough. Set an Arithmetic alarm when it isn't: it will not switch off until you have solved the maths, so you are properly awake before you can reach for snooze.

WAKE UP PROPERLY
• Arithmetic alarms — answer between 1 and 10 questions before the alarm will stop
• Three difficulty levels, from quick sums to something you have to think about
• Simple alarms too, for the mornings you don't need convincing
• Snooze when you want it, and a one-off alarm switches itself off after it rings

RELIABLE BY DESIGN
• Rings over the lock screen, the way your phone's own clock does
• Keeps ringing if you swipe the notification away — a swipe is not an answer
• Survives a restart: alarms re-arm themselves before you even unlock the phone
• Exact timing, not "somewhere around then"

MAKE IT YOURS
• Import any audio file from your device as an alarm tone
• Trim a long one down to the part you want — drag the waveform and hear it before you keep it
• Or pick from the alarm sounds your phone already has
• Themes: solid colours, gradients, textures, hand-drawn scenery, or your own photo
• Crop a photo as you choose it, so a landscape picture isn't cut down to a narrow strip
• Light and dark, tuned per theme
• Repeat on any set of weekdays, or just once

COMPLETELY OFFLINE
• No internet permission at all — the app cannot send anything anywhere
• No account, no sign-in, no email address
• No ads, no tracking, no analytics, no third-party SDKs
• Your alarms, tones and photos never leave your phone
• Cropping and trimming happen on your phone — nothing is uploaded to edit it

Free, with nothing to buy and nothing to subscribe to.

WHY THE PERMISSIONS
An alarm clock needs a few sensitive permissions to actually wake you, and none of them are used to collect anything. Exact alarms so it rings at the minute you set. Notifications, because a ringing alarm is a notification — without it the alarm screen cannot open. Run at startup, because Android does not keep alarms across a reboot. A foreground service and wake lock to keep the tone playing and the screen awake while it rings.
Offline alarm clock with math puzzles, custom tones and themes.

What’s new

Set any photo as your theme, and any sound as your alarm.

• Crop a photo when you choose it — landscape pictures are no longer cut down to a narrow strip
• Trim a long sound into an alarm tone. Drag the waveform to pick the part you want and hear it before you keep it
• The Tones screen now leads with the sound your alarm will actually ring with
