Install the app
Tutto Tracker is a web app. You can install it straight from your browser, complete with its own icon and full-screen window. No app store, no account and no 47-page agreement written by a committee of exhausted lawyers.
Visit tuttotracker.com in Safari. Other iPhone browsers may work, but Apple still keeps the good cutlery in its own drawer.
Tap the Share button: the square with the upward arrow. It is usually at the bottom of the screen.
Scroll down and tap “Add to Home Screen”. If shown, leave “Open as Web App” enabled.
Confirm with “Add”. The TUTTO icon now appears on your home screen, looking suspiciously legitimate.
Visit tuttotracker.com in Chrome.
Tap the three dots in the top-right corner.
Tap “Install app” or “Add to Home screen”. Android changes the wording occasionally, presumably for cardio.
Tap “Install”. The TUTTO icon appears among your apps and opens without browser furniture.
It opens in its own window and uses the TUTTO icon. Underneath, it is still the same website, just wearing better trousers.
After one successful online visit, local games, rules, tips and this guide remain available without internet.
Local scores, player names and settings stay on your device. There is no account and no cloud profile quietly judging your house rules.
Shared rooms synchronize through a room code, so they need a connection. Offline dice remain stubbornly unsociable.
When you open the app online, it checks for a new version and updates its offline files. You do not need to visit an app store.
Delete the icon like any other app. This removes the installed shortcut; your browser data may remain until you clear it separately.
The Web App Manifest supplies the app name, icons, theme colours, start URL and standalone display mode. The browser uses that metadata to create the home-screen app. There is no native wrapper or App Store binary.
A service worker sits between the app and the network. It precaches the tracker, all six language versions of the rules, tips and install guide, plus the shared CSS, icons and manifest in a versioned Cache Storage bucket.
Page navigations use network-first: fresh content wins online, with the cached page as the offline fallback. Static assets use cache-first. Requests to /api/ are excluded, so online room responses are never treated as reusable offline data.
Local games are serialized as JSON in localStorage. Scores, player names, settings and house rules stay inside that browser profile on that device. Clearing site data removes them too.
A Cloudflare Worker exposes the room API and stores shared game state in Cloudflare D1. Clients write changes with PUT requests and poll for newer state roughly once per second. API responses use no-store, and a scheduled job deletes rooms that have not changed for 30 days.
The service worker cache has an explicit version. A deployment bumps it; the new worker downloads the current core files, activates, deletes older caches and takes control of open clients. The next navigation can then use the new build.
