Bought the key, and still seeing ads. In fact, when I try to process an ISO, the app shows a full-screen ad, then kicks me back to the ISO selection screen, but doesn't let me select an ISO. It seems to be processing at that point but never finishes. This hanging didn't happen with smaller ISOs on the free version. Please help me out, I don't actually want a refund. UPDATE: Cleared data and I still see ads, but it works. Hangs after converting one ISO and has to be force closed to do another. Fix these issues for 5 stars from me.

The Best ISO Compressor App For Android So Far.

In concept, it's a godsend. I purchased the key and - 1. It still has ads. Which, okay fine. It's a minor annoyance. But - 2. Even after granting both the app and key permissions, I continue to get an error.

I granted permission to access storage from within the apps settings page and this app still doesn't show any of my downloaded Iso files.

I installed this app and it won't let me open it all it gives me is the uninstalling option the free version opens well but i have a ios that is 1.47 gb when your free one cant compress so o bought this app and i cant open it jelp plz.

You can pick your compression level to 9 this will either cut off 10mb to a whooping 500mb it just depends on the game. It also won't change any of the textures or speeds if your using PPSSPP. It can be useful on the larger scale games Kingdom Hearts, God Of War, ext. Worth the 1 buck.

So the app does not have any real function other than to steal a dollar from you. The free version will tell you that the file is to big an buy the pro version. Pro version flashes an spits out a few lines of in coherent txt.... Good play on the Devs part.

Keeps getting errors on every file I try to convert to CSO. Please fix and will increase rating.

Mat. F. Sep 11, 2015     

Works well. Cuts the size of my iso files down by 1\4 to almost 1\3. Compressing Crisis Core alone gave me a whopping 500mb back. I've had an issue with the "select" button not always working but that is nothing a copy and paste cant fix. It is a shame there are so many bad reviews from people who simply don't know how to use the app. Please tell me you have psx, sega cd/saturn/dreamcast and turbo graphix cd versions coming! Thanks for great work.

It saves me a lot of space. I definitely recommend this.

Just took my money. Try to convert & displays a ton of error jargon and doesn't do anything.
