There is zero reasons to download this – ReliCam Review

There is absolutely no benefit on downloading this and using vs. using the native photo app. The positive reviews must be shills and like many other reviews, just posted via the developer. There are no RAW settings, the photos are JPG and HIGHLY COMPRESSED. In fact the native photo app is essentially 1000% better at taking pictures than Relicam. The manual focus does not allow you to take tack sharp pictures, it just won’t happen. Uninstalled and on to the next app to test.
