GalleryWall
What it is
GalleryWall is a free Android app that creates wallpapers with AI models running on the device. Its Automation tab can refresh wallpapers periodically using a prompt builder and custom intervals. The app groups recent images by date and lets users manage providers, choose local models, or download models from GitHub. Styling choices include Black & White, Sepia, Invert, and Blur filters, plus Fit, Fill, and Seamless Pattern Tile options. The README says local inference supports offline use and that the app can start directly after a device restart. The maker says prompts, generated images, and model configuration are processed and stored on-device rather than 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; the README lists a Stable Diffusion model file of about 1.78 GB. The project is licensed under Apache License 2.0, and bug reports or feature requests can be submitted as repository issues.
