Duo Fold Transition

Compatible with all apps and foldable phones, including the Samsung Galaxy Fold 8.

Choose from a wide range of effects to customize your opening animation and achieve the look that suits you best.

Display a video or an image from your gallery during each animation. Track the number of openings and closings with a counter.

The "Duo" effect is heavily inspired by the iPhone Duo animation. However, certain technical limitations prevent us from reproducing it exactly.

WHY THE APP USES AN ACCESSIBILITY SERVICE

To extend the image from the external screen while the phone is opening, the app needs the last image displayed on that screen, just before the phone opens. It obtains this image through an Android Accessibility Service, which is used solely to capture a small image of the screen twice per second.

This is the only purpose for which it is used, and it is exclusively for the animation described above. The app is not an accessibility aid.

What the service does not do:

it does not read what is displayed on the screen: no text, input fields, or passwords;
it does not record what you type;
it does not change any settings or ever act on your behalf;
it does not interact with any other app.
Your data never leaves your phone. The images are used to display the animation and then immediately discarded: nothing is stored in the phone's memory, and nothing is sent over the Internet. The app contains no advertising, tracking, or user account, and works entirely offline.

You remain in control: the app explains all of this to you and asks for your consent before anything is activated. The service only starts if you enable it yourself in the Android settings, and you can disable it at any time from Settings > Accessibility.
