I really like this app but there is an issue

i downloaded this app a while ago and i really liked it. Then i deleted it cause i wasnt really used it, when i installed it the other day on my 2013 macbook pro retina. The fan just started getting crazy and it really killed the battery. For some reason the app became very heavy and tugged on the cpu and battery. Please fix
