This app is effective at freeing up RAM. I choose the 'Fill Full RAM Slowly' option but it's quick anyway. It allows me to run an app for awhile longer without it crashing, before the other few apps wind back up in the memory that restart themselves automatically. An ad will show right after the splash screen, before the actual app main page is shown, but the ad can be closed by tapping in the upper right corner after a few seconds. Overall, a fast and reliable way to temporarily regain RAM.

this app can also help trim other apps memory but the other apps might crash if you abuse it too much and the issue is if you clear the memory it doesn't work its till Staying pretty high but a restart helps

Crashes when filling the memory... Shouldn't Android kill other apps before killing the one used by the user? 😮
