Caliu runs everywhere you write, and every app works with the same notes, synced through your account.
The web app
The web app lives at web.caliuapp.com and runs in any modern browser. It is a full offline-capable app: you can install it as a PWA (look for "Install" or "Add to Home Screen" in your browser) and it will keep working without a connection, with your notes stored on the device.
The iPhone and iPad app
A native app built for iOS and iPadOS, with the same warm design, widgets, a share extension for sending content into Caliu, and full offline support.
The Mac app
A native Mac app that shares its codebase with the iPhone and iPad app. Same notes, same themes, plus desktop touches like drag and drop into the note list.
One account, every device
Sign in with the same account on each app and your notes, tags, and attachments stay in sync automatically.
The website at caliuapp.com is where you will find product news, the API documentation, and the viewer for notes people share with you.
