Every idea has its own shape.
A thought to develop, the weekend shopping, a project in columns, a snippet worth keeping. Pick the note type that fits, then find it again with categories and search.
Text notes
Headings, lists, images and formatting, from the toolbar at the bottom. For notes, drafts and thoughts that need more than one line.
To-do lists
Tick items off, drag them into order and see at a glance how many are left.
Kanban boards
Columns and cards you move with a finger: a house move, a launch, the week ahead.

Privacy & sync
Always in sync. Only yours.
Your notes leave the device already encrypted and land in a cloud you choose. Only you hold the key: not even we can read them.
End-to-end encryption
Notes are encrypted on your device with a password only you know. What reaches the cloud is unreadable.
Fingerprint or secret code
Private notes stay hidden until you unlock them.
You choose the cloud
Your own Google Firebase project, free, or the open-source FastMemo Server on your PC, NAS or Raspberry Pi.
End-to-end encryptedFingerprint lockEvery platform
Start on your phone. Finish at your desk.
Android, Windows, macOS and Linux: the same app and the same notes, in sync on all your devices.
