Don't make the same mistake I did...
Best HDR Pro by CYS Creative

Well this app is not worth a plugged nickel... Total scrap.
In description it says auto, semi-auto or manual modes.
The app only has one mode, HDR is either on or off, no semi-auto nor any manual modes.
Difference between HDR on and off is very minor.
All editing is Aviary so only way to get an image that even looks HDR is to play around in curves.
It does save images at full device resolution.
Because it's claims are mostly false in AppZapp it's going to be a developer that I will block, don't need nor want to see anything else. I hate developers that have false claims in descriptions...
Currently supposedly on sale for 60% off at $2.99US
Will give iTunes supports new refund system a try. Actually it's more interesting then this app
If you go to iTunes support, then account and billing then scroll down to report a problem.
For apps you have bought in the past 90 days you will find them in a new list with the apps icon, name, price etc. select it and it opens a requester where you describe the problem. Send it and a few seconds later get the message that it's been refunded.
The other day I bought Harris Shutter Camera - Lomo Style... on my iPad I get a blank black screen and will not take an image, nor do anything else. So I went through this new iTunes setup and in only a few minutes it was refunded and account within an hour showed it. Much simpler then the old system where you actually were issued or denied by an actual person and took normally a couple days before they would approve and then a few more days before it actually was refunded and showed.
Now all I have to do is wait for the app to show in the list so probably by morning...
Edit
Showed up in the list this morning so I got my refund (pending) the message said their normal 3-5 days for it to show in iTunes. Last time was only a couple hours so will see how long this time.
