Auto Wallpaper vs GalleryWall

Auto Wallpaper is a desktop app that uses AI to make wallpapers based on the current weather and time of day. It can change wallpapers automatically at an interval you choose, and lets you save favorite creations. Prompts can be collected in albums and generated in sequence or at random. The README lists a 4K resolution option and high-detail upscaling. The app automates image generation and upscaling through Leonardo.ai, and uses 1secmail.com for temporary email. Installers are linked for Windows, Linux, and Mac. Its maker describes it as a free, open-source, non-profit hobby project, partly made to learn Tauri and intended for educational rather than commercial purposes. There is a significant caveat: a Cloudflare CAPTCHA on Leonardo.ai’s login page currently blocks the existing automation, and an update is needed. The latest listed release is v0.2.7. Bug reports can be sent through GitHub Issues; the maker also lists an email for questions or concerns.

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.
