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.

Review update: I bought this app primarily for the ability to read the GPS tags of photos and display the location on a map. My only quibble would be that I wish the photo could stay on the screen with the map at the same time, instead of having the photo and the map on separate tabs. Similar to how iPhoto used to do it. Tip: if you tap on the pin in the map view, you can now launch the location in the full iOS Maps app. Being able to see all the info about images is really nice - all kinds of details, really helps to figure out what was going on when a picture was taken. It's also very good of you want to know what personal information a picture contains before you post it on the Internet. Great app!

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.

App does allow you to modify exif metadata. But the interface for what I needed to change is needlessly awkward and time consuming. I am trying to fix the year within the date on pictures of my grandson taken by my daughter's friend. This would be helpful for historical reasons and to allow me to find them again by the correct dates later. This app will allow me to do this, but only one picture at a time, which is painfully slow, but, the interface to change the date is a scrolling wheel, and does not allow me to change the only character in the date field that is incorrect, the least significant digit of the year, which is off by 4 years. Instead of typing over one character, the interface requires me to use a scrolling barrel, which can only change by days at a time. I have to scroll across 4 years of days for each field within each pic. It does actually allow me to change the date, but it may take me a week to change the 60 or so pics with the wrong date, due to the interface.

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.
