The app is now a Progressive Web App. That means you can install it on your phone from the browser and it will look and feel like a native app — no app store required.
On Android: open the app in Chrome and tap “Add to Home Screen”. On iOS: open in Safari and use Share → Add to Home Screen. Done.
It works offline for cached content, handles background updates gracefully, and gets a proper icon on your home screen. Give it a try — especially if you are testing the UX on a real device.
