It's one thing to put ads on a free version of an app but this one has them popping up with extreme frequency. I've seen ads that force you to watch for 30 seconds (intolerable) but this app's ads are not close-able unless/until you actually click on the ad, which pops up a new tab in Safari. In my view that is a bridge too far and makes this app unusable. I will give the benefit of the doubt however, and assume this is a fixable glitch to make the ads close when the "x" is pressed. I would pay 1-2 bucks for an app like this and skip the distraction and inconvenience of ads altogether, and there are better apps available for free and ad free at that. Nevertheless, there's enough decent content here for a beginner like myself to learn a few things, and assuming the ads get modified to make the app usable, I'm giving it the full 2 stars it will deserve once the ads are fixed (as opposed to the 1 star it deserves right now).
