Small · Fast · Native

Apps that do one thing well — and stay out of your way.

The Let apps are a family of small, fast tools by Martin Betz. They live on your devices, sync when you ask them to, and don't fight you with accounts, ads or lock-in.

Tasks

Let Tasks

Tasks, projects, areas and tags — captured fast, synced over a clean REST API. Built for keyboard-first people who think in lists, not kanban theater.

Notes

Let Notes

Encrypted notes for your Mac. One shortcut from anywhere, instant full-text search, Markdown inside, SQLCipher underneath. Private wiki, zero cloud fuss.

Files

Let Files

Your files, your server. A lean client that treats your own storage as first-class — no sync-engine surprises, no subscription.

Count

Let Count

Simple counters for everything worth counting: habits, reps, coffees. One tap to increment, history when you want it.

Cards

Let Cards

Flashcards, done quietly. Create, review, remember — on your schedule, on your device.

Music

Let Music

A local music player that respects your library: fast, native, and happy with big folders of files. Your music, playable in seconds.
