Before generating a report

Check that every required checkpoint has a valid before-and-after photo pair. If your job has no required checkpoints, complete all applicable checkpoints. Then open the report preview to review the content before saving.

Finding a saved report

Open the document archive in the app to view saved PDFs and share them again. A copy saved to a location outside the app is managed separately by your device or the receiving app.

Frequently asked questions

Can I use photos I already have?

Yes. Import photos from your gallery or take new photos with the in-app camera. Assign them to the before and after stages of a checkpoint.

Can I make my own checklist?

Yes. Create a custom template with checkpoint names and capture guidance. Mark items as required or optional, then reuse the template for separate jobs.

When can I generate a report?

Complete required checkpoints with valid before-and-after pairs first. If there are no required checkpoints, complete all applicable checkpoints. The app shows your progress before report generation.

Does the photo workflow work offline?

The core job, comparison, and PDF workflow uses local storage. Features that contact external services, such as Google Play purchases and email support, need a connection. See the Privacy Policy for data handling details.

Are my original photos changed?

Photo annotation and report generation use separate data or derived files. They do not overwrite original photos in place.

Which devices is it available for?
