Norwegian Verbs Pro. LearnBots

This should be a great app. I tried the free version and although there's only a handful of words on it, I liked it enough to want the pro-version. I got several messages telling me it was on special offer from £6.99 down to £2.99, so, liking what I saw I decided £2.99 would be a bargain. It's not. I think there's about 100 verbs in total on it, and many of these I already know. At no point does it tell you how many verbs you will get in the pro-version. I expected there to be a few hundred at that price. I feel cheated, especially considering that the verb tenses aren't too hard to learn. I haven't checked to see how many irregular verbs there are. I would hope that the majority are for this price, since they are more difficult to learn. There is nothing pro about this. However, that is not it's only failing. When I added my own verb to it I could only add the present tense. I cannot get it to add any other tenses. It just throws me back to the screen with the list of verbs. Absolutely useless! I really wanted to love this app, because everything is great but it's costly for very little.
