Why my pictures looks disaturated on FlickStack app on ipad and iPhone? But looks ok Facebook app or browsers?

I have no idea why does this happens ..I haven't changed any colors settings in photoshop, I've tried different color profiles too
Yes I do use this profile

Use the sRGB colour profile for images intended for the net. It's the world wide standard for colour reproduction on the net.

Edit > Then you are doing all you can do. Perhaps there is a problem with the app you are using. If the app doesn't support standard colour profiles, then that's the fault of the app developer.
