Horrible ad-ware for paid app. – nvDXF Lite Review

So, it works. That’s where the good news stops. You can only open one file at a time. It’s not simple to do so, it doesn’t auto-overwrite... etc. you have to delete and re-import. It constantly nags you to buy the paid version. At one point I had to click the nag screen ten times straight to get back to the app to delete the file. I understand they want you to use the paid version, but this is blatant abuse of the App Store and the principal of what freemium apps are about.
