A free app for Android, by Real World Apps 2018.
Photo Collage Maker & Editor is the most powerful and user-friendly tool to create high-quality collages. It allows you to combine up to 15 photos into a single image, and it has a wide range of effects and styles you can apply to each individual photo. You can also add text, draw on the image, and use a variety of different shapes and colors to create an original and personalized collage.
The app can be used in two ways. You can either import photos from your camera roll or add photos from the Gallery. Once you’re done, you can then apply one of the many available filters, add a background, and apply any other effects or draw on the image to create an original and personalized collage.
