An offline reminder app for Android that keeps everything on your phone
Most reminder apps are really cloud services with a phone screen on top: your list lives on their server and syncs down to you. SayStash works the other way round. Everything is stored on your phone, and reminders fire from your phone, with or without a connection.

What "offline" means in SayStash
- Reminders fire without internet. They're scheduled on the phone itself as normal Android notifications, so airplane mode or no signal doesn't stop them.
- Your list is stored on the device. Notes, reminders and events are saved on your phone. There's no SayStash server and no cloud sync.
- Typing works fully offline. Add, edit, snooze and complete entries with no connection at all.
- No account. Nothing to sign up for and nothing to log in to, so there's no login screen to get stuck at when you're offline.
SayStash turns speech into text with your phone's built-in speech recognizer. On most Android phones that's Google's, and depending on your phone and language it may need a connection, and it may send audio to Google. If you're fully offline or would rather keep audio on the device, use the typed quick-add. Everything else works the same.
Backups you control
Because nothing syncs to a cloud, the backup is yours to keep. In Settings, Export saves everything as a single JSON file you can store wherever you like. On a new phone, Import brings it all back. If you uninstall SayStash without exporting, your entries go with it.
Reminders that actually arrive on time
Android sometimes delays notifications by a few minutes to save battery. SayStash's Settings shows whether exact timing is on, with a button that opens the Android setting, so your reminders land on the minute. When one arrives, tap Done or Snooze 10 min right from the notification.
Who it's for
- People with patchy signal: commuters, field workers, travellers, anyone in a building with no reception.
- People who'd rather their reminders weren't stored on someone else's server.
- Anyone tired of making an account just to be reminded to take the bins out.
What it doesn't do
No sync means no sync: SayStash won't show your reminders on a second phone, a tablet or a computer. It also isn't a full task manager. There are no projects, shared lists or checklists. It's built for capturing the next thing you need to remember and making sure your phone tells you at the right time.
