Disappointing effort from a dev I trust – Verb Tenses Review

I saw the negative star rating, but I took the plunge and bought this app. I bought it because I thought other apps from AAT, such as American Accent and Syllables, were very useful. I guess I expected there to be some explanation of all the verb tenses illustrated by accompanying tables and example sentences. What you get are 9 tables with audio. That's it. I realize this is only $2, but I'd rather pay more for something more useful. I had hoped might get a handy teaching reference, but it disn't work out. Using American Accent got me excited about the upcoming Grammar app advertised by AAT. This app, unfortunately, has curbed that enthusiasm.
