App install and update problems
Fix problems installing Engineer OS on your phone's home screen, and make sure you're running the latest version.
Updated 11 October 2026
Engineer OS installs from your browser, not from the App Store or Play Store. The steps are in Install Engineer OS on your phone. If they don't work, try the fixes below.
Can't install on iPhone
- Use Safari. Open your company's address, tap the Share button, then Add to Home Screen. If you don't see it, scroll down the share sheet, or tap Edit Actions to add it.
- Make sure you're on your company's app address (e.g.
yourcompany.engineeros.uk), not thewww.engineeros.ukwebsite. - If an Engineer OS icon is already on your home screen, use that one, or delete it and add it again.
Can't install on Android
- Use Chrome. You'll usually see an Install App card on your home screen in Engineer OS. If you tapped Not now, open Chrome's ⋮ menu and choose Install app or Add to Home screen.
- If the option is missing, check you're on your company's app address and signed in, then reload the page.
The app looks out of date
Engineer OS updates itself; there's nothing to download. A new version is picked up the next time the app loads with a connection. If a change the office mentioned isn't showing:
- Close the app completely (swipe it away), then open it again.
- Still old? Close and reopen it once more. It can take two opens to switch to the new version.
The app opens to a blank or old screen
- Check you have signal. The app needs a connection to load your latest jobs.
- Close it fully and reopen it.
- Still stuck? Delete the home screen icon and install it again from the browser. Your jobs and data are stored online, so nothing is lost; you'll just need to sign in again.
Notifications
On iPhone, notifications only work once the app is installed to your home screen. See Push notifications not working.
Still stuck? Email support@engineeros.uk with your phone model and what you see.
