Time tracking as an app – everywhere, no install

Most time tracking apps require a download from an app store, an account with the vendor and regular permission to update. Zeitbro takes a different approach: the app runs entirely in the browser and is installable as a Progressive Web App (PWA) directly to your phone's home screen or desktop – no app store, no waiting for approvals.

What that means for you: open the page, log in and start immediately. Anyone who wants to can add Zeitbro to their home screen via the browser menu and from then on has an app experience that is barely distinguishable from a native application – fast load times, its own app icon and no browser bar in sight.

Whether you use an iPhone, an Android device, or a Windows or Mac computer – Zeitbro runs on every modern browser without a separate installation. The interface adapts to the screen size, so you work just as comfortably at your desk as on your smartphone on the go.

As a PWA, Zeitbro can be added to the home screen on iOS and Android. On desktop it can be installed as a standalone app in Chrome and Edge. In all cases your entries sync in real time, so you can switch between devices seamlessly.

A poor connection on the train or a brief Wi-Fi outage should not interrupt your time tracking. Zeitbro caches entries locally and syncs them automatically as soon as the connection is restored – without any action needed on your part. Running timers are stored server-side and keep ticking regardless of whether the browser is open.

As soon as you open a second device, you see the current state immediately – accurate to the second. Start a timer on your phone and it appears at that same moment on your desktop. That makes Zeitbro a reliable foundation whether you are working from home, at the office, or on the road.

Create an account, log in, start the timer – that is all it takes. There is no app to download, no configuration files and no learning curve. The interface is reduced to the essentials: clock in, clock out, breaks and overtime are calculated automatically.

Anyone who wants to use Zeitbro as a PWA simply taps 'Add to home screen' in the browser – done. The next time you open it, Zeitbro launches like any other app, completely without a browser address bar. Updates are applied in the background without any action required from you.
