GalleryWall

What GalleryWall is

GalleryWall is a free Android app that creates wallpapers with AI models running on the device. Its Automation tab can refresh wallpaper on a schedule, using a prompt builder and custom intervals. The app organizes recent wallpapers by date and lets users manage providers, choose local models, or download models from GitHub. Image options include Black & White, Sepia, Invert, and Blur filters, as well as Fit, Fill, and Seamless Pattern Tile layouts. The README says local inference can work offline and that the app supports direct boot after a device restart. The maker says prompts, generated images, and model configuration are processed and stored on-device, not sent to its servers or third parties. However, its privacy policy lists Google Play Services and notes that third-party services may collect identifying information and error logs. Local generation may use substantial device resources and battery, and the README lists a Stable Diffusion model file of about 1.78 GB. The project is open source under Apache License 2.0; bug reports and feature requests can be submitted as repository issues.
