PhotInfo

...for viewing and correcting metadata. The ‘share’ sheet shows metadata across all apps I have tried. Until Photos app and OneDrive give access to photo details, this is super helpful.

I’ve tried using this app for many photos by correcting the original photo taken date in the EXIF field, since many of my photos are scanned from prints. The app allows me to change the date but when I save the data it reverts back to the original date every time. I’m on the latest iOS 11 on an iPhone X.

It's amazing how much information is included in EXIF data. With that in mind, it's important to me to be able to find and read the data. I've enjoyed using PhotInfo while I hone my photo skills with my new DSLR. It makes it easy to see the values that I use most often. Most EXIF-reading apps seem to be built by developers who use Excel. Photinfo looks and feels like it was developed by a photographer. All the data is well organized and easy to read. Most of the time, I'm browsing my photos in the Photos app, and I'll see a detail (motion blur, blown details, dark exposure) and I'll wonder what I did, and what I can do to correct it in the future. It's great that I can use PhotInfo to see that information without leaving the Photos app. PhotInfo makes working with my photos so much more smoother and more informative and it's helped me become a better photographer. If you are aware of the existence of EXIF data, you want this app.
