Tap through the Android install, pick a folder for each project, and you are up in under three minutes without ever entering a login.

Photograph installation sheets, gas safe certificates and commissioning evidence, and the app suggests a tidy file name without pixel peaks.

Keep every doc in place under the right project, add dates and descriptions, and rearrange a photo in two taps.

When a project ends, one output fills a PDF organiser for the householder, inspector or your accountant, no clever devices needed.
