RAM Cleanup is an Android app developed by J Kosa that helps users optimize their device's RAM. With advanced features such as auto-closing and auto-start functions, users can easily manage their device's RAM usage. The app also offers customization options such as color settings for texts, background, foreground, and animation. Additionally, the app provides a shortcut for customized app-start and a side launcher that offers quick access to the app and many extra functions.

It is worth noting that the app uses accessibility service for back/home/recent app/open notification/screen move/split screen/quick settings/pointer mode and not for personal data collection. A paid option for no-ad on the app and minimization is available as a monthly subscription. However, users should be aware that if they do not cancel the automatic renewal within 24 hours, the contract period will be automatically renewed. Users can check and cancel the contract details from Google Play (Settings tab > Subscription > RAM Calc).

Overall, RAM Cleanup is a unique and useful app for users looking to optimize their device's RAM and improve its performance.
