Smart RAM Booster

Most of Android devices bundle with limited memory. Android task manager will selectively kill low priority tasks in order to
reserve memory to higher priority task. That's not always run at an appropriate time, causing low responsive apps, lagging,
especially when you launch a new app after heavily browsing web pages. It causes a worse experience.
