Unfold a new screen and inspect its colors, touch grid and crease patterns before making your own wallpaper.
Begin with your screen: inspect five solid colors, trace a touch grid, then compare a gradient with diagonal lines. These visual checks also work on ordinary, non-folding phones. They do not diagnose faults.
Make the screen yours with a photo. Preview a centered crop, enter separate outer and inner pixel dimensions, and save each wallpaper individually to Photos. Set the wallpaper yourself in system settings.
Three visual checks and one saved wallpaper are free. A one-time purchase unlocks more exports and device reading tools. Hinge angle and fold regions appear when data is available; open/close counts run only while the app is active. Battery shows one overall value.
Photos are processed on your device, with no ads, usage analytics or photo uploads to the developer.
