Houre

Houre is an end-to-end encrypted note-taking app built around a single chronological feed. Instead of opening a blank document, you write into a stream that works like texting yourself: type a thought, send it, and it lands at the bottom of the feed with your earlier notes above it.

Notes can be grouped into color-coded projects, linked with inline #tags, and turned into tasks tracked in Todo and Done lists. It also supports reminders, basic formatting (headings, lists, quotes, bold, italics and code), photo attachments, full-text search, and capturing text or links from other apps through the share menu. Everything works offline and syncs when you reconnect.

Notes are encrypted on the device before they leave, so the server only stores ciphertext. Projects can be shared by email invitation for real-time collaboration while staying end-to-end encrypted, with key fingerprints to verify invitations. The free plan works offline on a single device, while the paid plan adds sync across devices, your own shared projects and 5 GB of storage.
