Tomo

A native macOS library for the books on your shelves and the ones still to come.

Organise your library. Group books into collections of your own, swap a cover when one doesn't fit, fix the details when they're off.
Send to device. Plug your Kindle in. Drag a book onto it. Format and cover sorted on the way over.
Search beyond your shelves. Project Gutenberg comes built in. Add your own sources when you need more.
Take it anywhere. Your library is a folder of files. Move it, sync it, copy it to another Mac. The books outlive the app.

Or install via Homebrew:

brew install --cask pdrbrnd/tap/tomo

Requires macOS 26 or later.

Privacy

Tomo is local-first. Your library lives in a folder you own; nothing about its contents leaves your Mac. The app reaches the network only when you ask it to — to fetch metadata, search a source, or send a book to a device.

Two background pings exist and are disclosed here. Sparkle checks appcast.xml for updates. Sentry receives a crash report when the app fails — stack trace and macOS version, no library contents, no file paths under your home folder. You can turn crash reports off in Settings → Privacy.
