~/mahiru-tracker

A small tracker for one question: are you lifting more than last time?

Your plan, your weights, one tap per session. It installs onto your home screen like a normal app, opens without an address bar and works with no connection at all.

After that the icon opens it like any other app — no address bar, and it starts with no connection.

Open the app

Where your data lives

On your device, in this browser. There is no account and nothing is sent anywhere — the whole app is a single page and a database that never leaves your phone.

Two things follow from that. A second device keeps its own separate history, and if you wipe website data, the history goes with it.

So there is Menu → Backup: it writes everything into one file you can keep, and reads it back.

This is the icon you are looking for afterwards.
