WhatWhenHow is the fastest way to track anything in your life. One tap, and it's logged.

Make your own buttons for whatever you want to keep an eye on — headaches, coffee, workouts, a baby's crying, medication, moods, habits, anything at all. Tap a button and the moment is recorded with an exact timestamp. That's the whole idea: recording should take a second, not a form.

WHY WHATWHENHOW
• One-tap logging — no menus, no typing, no friction
• Your own event types — you decide what's worth tracking
• Backdate in seconds — forgot to log it? Set when it really happened
• Labels for context — tag an entry (mild, severe, gym, morning…) and reuse it next time
• Fix the last entry with a long press — change its date, time, or labels
• Reports that reveal patterns — see your activity by day of week, part of day, season, and label, plus the gaps between occurrences
• Recent activity at a glance — your latest entries with easy relative times

PRIVATE BY DESIGN
Everything you record stays on your device. No account, no sign-up, no servers, no analytics, no ads. The developer collects nothing about you. If you turn on Android's system backup, your data is copied only to your own Google Drive — never to us. Full details in the privacy policy.

EXPORT TO AI — FIND THE PATTERNS
Export your whole history to CSV in a single tap. This is how WhatWhenHow talks to AI: hand the file to an assistant like Gemini (and others like it) and ask it to read your data, surface the patterns you'd never spot yourself, and explain what's driving them. Simple taps go in, real insight comes out. You can also re-import the CSV anytime to restore your data.

WORKS OFFLINE
Fast and fully offline — no connection required, ever. Your buttons are always one tap away.

Tap. Track. Understand.
