SayWhen

One phrase — and it's on your calendar. No forms, no fields.
新版本 3.0.0
⚠️ New signing key.
This update will not install over the F-Droid-signed version. Uninstall SayWhen and install it again, this is a one-time step.
Your events are safe: they live in the calendar, not in the app. App settings, however, need to be set again.
Why: F-Droid now verifies that our build can be reproduced bit for bit, and ships the APK signed by the developer. It is the same signature as the GitHub build, so you can install from one source and update from the other.

In 3.0 the app supp
No forms, no fields. Just say when.

Type an event the way you'd say it, in English, Russian, Italian, Spanish, or German:

• Gym every tuesday and friday at 9
• Movie tomorrow at 11 for 1.5h !10
• Dentist june 3 at 12:30

SayWhen parses the phrase as you type: date, time, duration, recurrence, a “!10” reminder. It shows a live preview of what it understood and writes the event straight to the calendar you chose. Tap the home-screen widget, type, done.

Private by construction:

• No sign-up, no server, no analytics, no identifiers
• No network access at all — the app doesn't even declare the INTERNET permission
• Two permissions total: read your calendar list, write the event you asked for

Events go to your calendar and nowhere else. If your calendar belongs to a synced account, its own sync engine uploads the event, exactly as with any other calendar app.
