Photo Window app allows users to create unique and creative photo effects easily. Developed by Vacuapps s. r. o., this free multimedia app is available on Android devices.

With Photo Window, users can choose from different shapes of the picture window, such as elliptical or polygonal, to create picture-in-picture (PIP) effects repeated to infinity or funny face effects. Users can set up the effect in real-time pip camera preview or use photos from their gallery. The app also allows users to shape beautiful artworks based on animated droste effect.

Once the photo is ready, users can save it and get dragged into the infinity. The app also offers editor features to improve the creation and fly straight through the picture in an immersive 2D/3D animation. Users can create funny animated GIF images and share their funny photos, selfies, or GIF animations on social networks or via messengers.

It is important to note that the app has a photosensitive seizure warning, and users should read and understand the risks involved with the usage of the app. Additionally, sharing of GIF animations might not work on certain social networks due to the lack of GIF support on their side.

Overall, Photo Window is a fun and creative app for those looking to add unique effects to their photos.
