I posted a really rude comment ( I have already deleted it ) and I'd like to apologize. The app is not as good as its iPhone counterpart but its very far from bad. After commenting said comment, I used it continuously and found it to be useful and enjoyable. Moreover, this is the only app that offers this kind of features for free! Unfortunately, I cannot donate myself due to several reasons but I would encourage users to donate to the developer so that the app may become better.
