Has the potential to be good but like others said, there's just way too many ads. Like not just a reasonable amount to keep the app functioning but every click earns an ad. These ads don't give you a chance to breathe either as they're hyper sensitive to the point where just hovering your finger sends you to Google play. Not to mention their own ad for a paid acc that's also persistent. This app is too underdeveloped in missing common stones to be insisting on payment at this time. Improve first
