Paid app

This is not a free app, but a paid one. I do not mind paying for an app but don’t want to feel as if I need to be tricked into buying one.
Edit: Thanks for the response! I was in the market for a mobile pdf program, but instead decided it is easier for my file management to just continue to do so on my computer.

Developer Response ,

I'm sorry to hear that you feel tricked. The reason this app is free is to offer users the possibility to see if the feature set is what they are looking for. I tried to make people aware of it by stating this right at the beginning of the app store description page.

love it

It has the same basic features like other pdf reader/editors and even some of them are better than. I can enjoy many pdf ebooks on my iPad with it.
