Site memory

Save sites and assets once. Return visits pre-populate with your last inspection data — faster every time.

Ready for clients and managers

How to install your app on Android

Step by step

  1. On your Android phone, open Chrome and log in here at sitecaddy.co.uk
  2. Tap Open app on your app above
  3. Log in inside the app with the same email and password
  4. Tap Install when Chrome offers it, or open the Chrome menu (three dots, top right) and choose Install app or Add to Home screen
  5. Open it from your home screen like any other app. It works offline once it has been opened once with signal

If Install does not appear

  1. Make sure the page is open in Chrome itself. Links opened inside WhatsApp, Gmail, Facebook or LinkedIn use a built-in viewer that cannot install apps: tap its menu and choose Open in Chrome
  2. Update Chrome from the Play Store, then try again
  3. A phone managed by your employer may block installing apps. You can still use the app in Chrome, or ask your IT contact to allow it
  4. Your reports are stored on the phone, inside the app. Do not clear Chrome's site data or uninstall the app without sending your reports first
  5. Still stuck? Email info@sitecaddy.co.uk with your phone model
