Don’t buy

This is false advertising and this ap needs to be pulled. I paid for an identification guide, not something that restricts me from all use unless I hook up twitter. Which I don’t have. Useless. I want my money back.

Easy to get past Twitter nagging...

Just click off the Twitter screen to go to the other screens with news links, videos and other info. Not as great as some of the others but the Twitter nag is easily dismissed. Taking 1 Star off for that, but I’m sure it has to be there to pay the bills.

Don’t buy this app

Rip off. Scam. I don’t have twitter account and not getting one. Just lost money because I can’t access what I paid for. Should be taken out of App Store.
