Which Android app can put interactive pets on my screen?

Pet On Screen is an Android application that provides a live desktop companion experience. The app places small, animated characters called Shimejis onto the user's screen, where they autonomously walk over and interact with other apps and interface elements. For users seeking a bit of whimsical, animated decoration for their device, it serves a specific niche. The primary features include a selection of cute character designs, customizable behaviors like auto-walking, and simple touch interactions that make the pets react. In a real-world scenario, these digital pets can crawl around a news feed, hang off the edge of the notification bar, or play while the user checks emails, adding a layer of passive entertainment. However, some stability issues have been noted in user feedback, with reports of the app occasionally failing to launch properly, leaving the Shimejis stuck on screen until a reinstall. The interface is straightforward, though the selection of free characters is somewhat limited, encouraging in-app purchases for more variety. It's a charming, lightweight option for personalizing a device, but its utility is purely decorative and occasional technical hiccups can interrupt the experience.
