Yup, but I'm saying to not just stop using it, if someone likes it well enough, they're free to. But even if you stop using it but still keep it installed on your phone, check the app in the app management to see how much data it has stored. As apparently there is, or was no cap to the size of the cache the app uses so it keeps storing, and storing, and storing, ....
I the past I used Clean Master and CCleaner to wipe some of that excess garbage, lately I've been using App Cache Cleaner : https://play.google.com/store/apps/details?id=mobi.infolife.cacheI find that installing, running and uninstalling helps more and is less annoying than the regular nagging to clean cache, as it's easy enough to reinstall when I feel it's needed (like after I've purged some apps)
