Still asking for payment, why?


As someone mentioned, I also paid for online videos and was supposed to get access to the videos on the app, but the app still asks me to purchase it.

I’ve written twice to the developer. The first time (many weeks ago) he said that it could “easily be fixed” but it obviously isn’t yet. He hasn’t replied to my last email, which was about 3 weeks ago.

It’s unfortunate because the videos are pretty good thus far. The app leaves much to be desired.

Update: I reinstalled the app and it worked for a little while. I just opened it today after a few months and it’s again asking for payment! Is this a scam? It must be because the developer doesn’t answer emails.

I Support the Concept

Halo 43

I have done some research into this project and felt the need to invest in it. It is proving to be worth the cost. Only problem is I already pre-ordered the videos online on my account, but the app says I still need to pay $20

Videos Are Great


The content in these videos is well worth the 20 bucks. I hope these guys are able to finish it all as planned. So much work!
