A mobile app that lets you capture and sync end-to-end encrypted notes offline-first without any setup
Capturing notes on mobile is broken for privacy-conscious users: apps that encrypt properly require self-hosted sync (Joplin) or complex setup, and the two best alternatives (Standard Notes, now under Proton corporate; Notesnook, bootstrapped and thin on mobile UX) leave a wide gap for a genuinely native mobile-first product. Users want notes that work fully offline, sync transparently when connected, and store nothing readable on the server, with no server configuration required by the user.

"I wanted a simple note-taking app that works offline first and is end-to-end encrypted. I couldn't find one I liked, so I built Unforget."
"A survey of the offline-first ecosystem in 2025 showing that most apps still treat offline as a degraded fallback rather than the default, and that sync remains the hardest unsolved UX problem for mobile-first tools."
