FastPhotoTagger

I have 2000 scanned images of trains I took in the 70s plus 3000 digital photos taken more recently. Each has embedded exif data such as a caption, tags, gps data, date taken etc. which was loaded semi-automatically via my laptop. I have looked high and low for an app that can select photos by searching the metadata and then display each one along with its caption. To me this is a superb facility. Seeing the captions with the photos is a bit like looking through (real) photos where the taker has written a bit about it on the back. I can view my photos quickly and efficiently whenever I like and unlike many apps, this one does not bombard you with irritating ads. Having decided which Exif fields to search on I have had very few problems using the app. After set up a typical search of the 5000 images takes around 10 seconds, and the selected photos are ready to view. Note: if you are using Fast Photo Tagger with Android 6 (Marshmallow) and wish to access an SD card make sure storage access is granted by ticking the box in Settings --> Apps --> Fast photo tagger --> Permissions. I am very impressed with this app as it allows me to search and display images quickly and easily.

This is a GREAT app. It's the only app I found where you can add and edit metadata, such as captions or keywords. It also accepts files over 100 MB (e.g. Nikon 16 bit scans). I don't use much memory, and I can't remember it ever crashed. And, the cherry on the cake, if you have any questions they are replied too quickly.

I've used it for +4y now & it has since become the only app I use for metadata. I can reliably both view & edit a vast range of tags for numerous file types. I can change dates of videos. I can use batch functions. I can edit files on my SD card directly. Extol is incomparable, though there is absolutely a learning curve. My favorite custom Extol command extracts file title to timestamp. I'm kind of shocked this app seems to fly under the radar & selfishly hoping the masses don't ruin it.

Freezes while trying to scroll in-app explorer.

Doesn't work for me. Just flashes on the screen S8 Plus, have to force close

Attempt to open the app on my Galaxy Note 8 just gives a blinking screen. Uninstalled.

Doesn't work on S8+. Ace just flashes.

Couldn't write in approximate values for gps tags.
