Common questions

How do I move my projects to a new phone?

In the app, open Settings and choose Create backup. Copy the file to the new phone, install the app and choose Restore backup on the first screen or in Settings.

How do I change units, currency or language?

Open Settings in the app. On Android 13 and newer you can also choose the app language in your phone settings.

How do I delete my data?

Open Settings and choose Delete all data, or uninstall the app. See Your data for details.

Why does my result differ from the shop's estimate?

Shops often use their own coverage or waste figures. Change the defaults in the app to match the product you are buying.
