Linux support is experimental.

On Android you have three options: grab the APK from Releases, install from RuStore, or set up Obtainium for auto-updates (below). RuStore handles updates for you through its own store.

Obtainium checks GitHub Releases and installs new APKs for you, so you don't have to download updates by hand.

1. Install Obtainium.
2. Tap Add App and paste this into App source URL:

   https://github.com/hacan359/tonkatsu_box
   

3. Tap Add.
4. The first time it updates, Android asks you to allow installs from Obtainium. Allow it once.
5. In the app settings, pick how often Obtainium checks for releases and turn on auto-update, or just refresh manually whenever you want.

When a new release ships, Obtainium downloads the APK and shows the system install dialog to confirm. Silent background installs are not possible on Android without root.

1. Download and install from the links above
2. Launch the app — Welcome Wizard guides you through setup
3. Start adding items from Search, or import ready-made collections

The app works offline after setup. API keys are built-in.

Move your whole collection from one device to another over your home network. No cloud, no account: the two devices talk to each other directly.

How it works:

1. Open Settings → Database → Device-to-device sync on both devices. While the screen is open, each device announces itself on the local network and finds the other one.
2. On the device that should receive the data, tap the other device in the list.
3. Confirm on both sides: the receiving device shows what it is about to download (device name, date, collection and item counts), and the sending device asks you to allow the transfer.
4. The full database is copied over and replaces everything on the receiving device. Restart the app when asked.

This is a full replace, not a merge. Changes made on the receiving device that the sender doesn't have are gone after the transfer.

Before replacing anything, the app keeps the previous database as a backup. Settings → Database → Backup → Restore swaps the current database with that backup, and restoring again swaps them back.

By default the database lives in the app's private folder. Settings → Database → Storage location lets you move it to any folder you pick — for example an SD card or a folder synced by a cloud client.

When you pick an empty folder, the app copies your current data there. When you pick a folder that already holds Tonkatsu Box data, the app switches to that data instead. Either way a restart is required. If the custom folder is missing on startup (unplugged drive, dead network share), the app falls back to the default location instead of failing — Settings shows a warning when that happens.
