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

There are 5 ways to boost
☆ Auto-boost: boost automatically under RAM available & timing conditions
☆ Overlay widget – Enable RAM Booster overlay widget (on by default), adjust widget’s position, and tap on widget to boost anytime you want
☆ Home screen widget – one tap to boost (long-press your home screen>Widget to add RAM Booster widget)
☆ Notification bar – one tap to boost (toggle notification bar visibility in app’s setting)
☆ Boost Now – tap this button from app’s main screen

Extremely satisfied ! Go for it . The app is very very efficient and just amazing. Even the storage cleaning is amazing and great. I just love it. Most of the apps out there do nothing when you try to clean your ram. But these people give you options on what and how ! They also offer a one tap boost. And the feature to select auto boost and the level of boost as strong/extreme/gentle/mediocre is amazing.

I've downloaded and have tested too many boosters, cleaners, and optimizers to count, and by far this one is one of the best, even on a low-end RAM device like mine. The critical feedback should by no means be the deciding factor in trhing this app, because as far as I can tell the critical opinions are more for astetics reason than actual performance. Hats off to the developer for this one.

Thought I would try this, so many of these RAM cleaner apps don't function right, but this one actually works. Plus it uses little MB. Even though my android is a Note 2, it has very good speed and never does any buffering. I am mainly interested in cache cleaners, creating more RAM, and having a longer use of battery.
