As part of HTC’s plans to release productivity-related apps and earn a bit of extra money, the brand released a new app called Boost+ to its Preview program users. The app is designed to check and clean your smartphone’s cache and RAM to help make it run faster. Some users who are testing the app say they’ve noticed an improvement with battery life and performance after clearing the RAM. It won’t be exclusive to HTC devices either and would be available to everyone who needs that “boost” once it’s officially published on the Play Store. Right now access to it is via the HTC Preview program only, where you’ll be able to download the APK.
