Open Source Android Screen Savers

Create a cross themed wallpaper by adjusting the sliders then pressing the camera icon. Change background or particle shape. A free live wallpaper version is available for Android via the Play Store ("ColorCross Free".) The video is of that live wallpaper in action. Done in 9 events in Construct 2.

Create customized spiral art for wallpapers using your own images. This version is HTML5 based - it runs on most modern browsers. Use the sliders to create just the effect you want or put it in shuffle mode for a screensaver style effect. You can also toggle the user interface on and off. Simply click/touch the camera button to save the current appearance as an image on your device. The rainbow effect requires WebGL and hardware acceleration enabled in your browser.

Device Watch is an Android device monitor with home-screen widgets, per-app usage insights and an interactive screensaver for charging or docked use. It works fully offline: the app has no internet permission, and every number is real data read from Android and kernel sources. The widgets show battery, memory, CPU, storage, Wi-Fi, mobile network, data usage, uptime and screen time. The app adds a screen-time chart, top data users, a last-opened list, device details, a 62-day usage history, 14 days of battery history and charging sessions, CSV and HTML exports and optional alerts. Shizuku or root, both off by default, unlock extended statistics. The screensaver shows a large clock, the next alarm, charging power and unread notification icons. In English and Finnish; also on F-Droid and Aptoide. Source code, issues and discussions: https://github.com/jrs8205/Device-Watch

Fundraisers SUCK! You know fundraisers, those things where we're guilted into buying overpriced poor quality products with way too much of the raised funds going to outside companies. You know those things where our kids hopes of prizes are inflated and then dashed or where our children are pressured with sales quotas. Fundraisers SUCK! We're here to change that. Introducing WaddaFundraiser! WaddaFundraiser provides FREE software for fundraisers to sell or use as rewards for donations so that the fundraiser gets to keep ALL of the funds raised! WaddaFundraiser's first project is developing a customizable, fun, eye-catching Android Live Wallpaper. A fundraiser will be able to customize the live wallpaper to provide a unique wallpaper all their own. E.g. a school will be able to easily replace the default graphics with the school's logo and colors. The WaddaFundraiser application will provide all the sizzling special effects.
