We use your name and email only to send your audit and talk about your app. We keep them while we are working with you (including while a quote or a build is open) and remove them 90 days after the last update on your request.

How it works

  1. Send your app linkYour business, a store link and how to reach you. About two minutes.
  2. We check it on Duo layoutsWe open your app on the Duo's inner and outer screens, folded and half open, and write down what breaks.
  3. You get a private reportA link to your own report with each finding and how serious it is. If you want it fixed, we send a quote.

What we check

The same six areas in every report, so you can compare, fix and check again.

  • Fold and hinge

    Buttons, text and forms that land on the crease when the phone is half open.

  • Layout

    Screens that stretch, clip or leave empty space on the 7.6-inch inner display.

  • Controls

    Tap targets and gestures that move out of reach between the two screens.

  • Accessibility

    Text size, contrast and screen reader order after the layout changes.

  • Performance

    Stutters and reloads when the app moves between the outer and inner screen.

  • Other

    Anything else a business owner would notice before their customers do.

Example, not a real customer. Your report covers your own app.

Fold and hinge

Severity: high

When the phone is half open, the Book class button sits on the crease: it is hard to see and easy to miss with a thumb.
