Getting Zeitflex on your phone

As an app on your phone — no app store needed

You add Zeitflex straight from your phone's browser to the home screen as an app: with its own icon, full screen and notifications, on iPhone and Android. Zeitflex is not in the app stores — you do not need them for this, so there is nothing to search for there. The app keeps clocking in and out when there is no reception, see below.

In the app: the “Mobile app” page

Once signed in, you find the same guide in the menu under Administration → Mobile app — for iPhone and Android, with the icons you have to look for on the device. Where the browser offers it (for example Chrome on Android), the Add to home screen button puts Zeitflex there with a single tap. At a computer the page shows a QR code that you scan with your phone. If Zeitflex already runs from the home screen, the app hides the menu item — then everything is done.

Creating a shortcut — iPhone (Safari)

1. Open Safari and sign in to Zeitflex.
2. At the bottom, tap the Share icon (square with an arrow pointing up).
3. Choose Add to Home Screen.
4. Confirm the name, done.

Creating a shortcut — Android (Chrome)

1. Open Chrome and sign in to Zeitflex.
2. At the top right, tap the three dots.
3. Choose Add to Home screen (depending on the version also “Install app”).
4. Confirm, done.

The result: A Zeitflex icon on the home screen. Tapping it opens the time clock — no address bar, no searching.

What the real app can also do

So that it is clear what you are waiting for:

• Biometric lock (fingerprint or face recognition) as protection on your own device.
• Photo of the sick note uploaded directly from the camera.

Clocking in without reception — this works in the browser

Until 27 September 2026 this section said the opposite. That was wrong, and we write it down instead of quietly swapping it out:

• Clocking in and out without reception works. Start, end, break start and break end go into a queue on the device and are sent on as soon as there is a network again — without duplicate entries. The time clock shows what is still pending.
• One thing needs a connection: discarding a running entry. That is deliberate. When discarding, the server checks the month lock and the assessment at the time of writing, and both can have changed by the time the entry is sent on. A withdrawal that takes effect hours later, unseen, would be the greater damage — so the interface says honestly that it does not work right now.

So anyone working on building sites without reception does not need a fallback. More on this: Working offline.

Still stuck?

If you cannot find the shortcut, it also works without one: Zeitflex works in any phone browser via the normal address. Save it as a bookmark.
