Free version? Doesn’t do much

Might be good, if you pay $3.99. If not, fuhgeddabout it.

Free version not worth downloading

I downloaded the free version to look at attachments in an email. It wouldn't open the attachments unless I bought the premium version. The free version is just a teaser and not worth wasting time on

Doesn’t work

I just paid $3.99 for this app and it doesn’t work. The app crashes before the winmail.dat attachment opens. And I’m guessing there’s no way to get my money back :(
