In their own words
GalleryWall
GalleryWall is an Android app that creates wallpapers using AI models running on the device. Its Automation tab can refresh the wallpaper periodically with a prompt builder and custom intervals. The app groups 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, along with Fit, Fill, and Seamless Pattern Tile layouts. The README says local inference supports offline use and the app can start directly 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. Its privacy policy lists Google Play Services and notes that third-party services may collect identifying information and error logs. Local generation can use substantial device resources and battery; a listed Stable Diffusion model file is about 1.78 GB. GalleryWall is free, open source under Apache License 2.0, and its README directs users to repository issues for bugs or feature requests.
