Don’t think the programmer understands meaning of Metadata – Metadata Review

I always want to have an app to see the metadata of my photos from my iPhone. After downloaded this app, I was not able to believe this is an app. The app only shows my photo size, file size and dpi. Some of my pictures were not even able to decode the dpi. GPS, no information was provided. I am wondering if the programmer understand what metadata is. Where is the data of the aperture, focus, iso, shutter speed, write balance, photo file number, photo actual size, and etc. I downloaded this app for free. It is good to test it for free. It is removed now. Not even worth to keep it in my tool belt.
