Alongside its new Android flagship, HTC is unveiling an app today that anyone running Lollipop or higher can download from the Google Play store. It's called HTC Boost+ and promises to "optimize, declutter and fortify" your smartphone with minimal fuss. First of all, that means clearing out unnecessary data such as cache files, app installers and general "advertising clutter." It also boasts a "smart boost" tool that supposedly frees up memory to improve performance. We'll reserve judgment for now, but it's widely believed that task killer and RAM cleaner apps have a negligible, if not detrimental effect on Android hardware.
