Smart RAM Booster
The most beautiful part of this app is a small, configurable widget that places on top of any app and one-click to RAM boost.
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.

RAM Booster comes with auto-boost in 4 levels: aggressive, strong, medium, gentle.

☆ Aggressive: kill most of low priority apps
☆ Strong: Kill apps that is low priority as well as consume lightly below an “average”
☆ Medium: kill apps that consumes memory above an “average”
☆ Gentle: kill only apps that uses considerable memory

☆ Boost Now – tap this button from app’s main screen
