ACHELYLog a headache in 2 taps, even mid-attack.
Achely is a headache tracker and migraine diary built for the worst moment: a dark, dimmed screen, one tap for pain from 1 to 10, one tap for Done. Every month of your history is free. No account, works offline.
Get it on Google PlayFree with ads. Achely Pro removes ads and adds trigger comparisons, pressure charts around each attack, detailed doctor reports with CSV, calendar widgets and themes — yearly, monthly, or once for life. Your history was already free.
6 headache days · 4 medication days
Avg pain 6 · last attack 4 days ago · −6 hPa in 24 h before it
Two taps, then rest
Tap your pain level and the attack is saved with the time. Add where it hurts and what came before it, then Done. Medicine, symptoms, aura and the end time can wait until you feel better.
Dark and dim
Attack mode turns the app near-black and lowers its own screen brightness, with no animations, sounds or ads. Your phone's brightness setting is left alone.
Log without opening the app
A Quick Settings tile and a home-screen widget open Attack mode directly. While an attack runs, a quiet notification lets you raise or lower the pain or end it.
Every month, free
A calendar of every month you have logged, headache days and medication days per month, and a one-page 30-day summary to share with your doctor.
Pressure from your phone
On phones with a barometer sensor, Achely notes the air pressure when an attack starts and the change over the 24 hours before. No location, no weather service.
No account. No cloud.
Everything stays on your phone and works in airplane mode. Undo a mistaken log in one tap, and back up to a file you control, optionally encrypted.
A diary, not medical advice. Achely is a diary, not a medical device, and does not diagnose, treat, cure, or prevent any medical condition. Talk to a healthcare professional about your headaches. Patterns in your log are not proof of a cause. If a headache is sudden and severe, or comes with weakness, numbness, confusion, fever, a stiff neck, vision loss or a seizure, or follows a head injury, get emergency help.
