wish to have a gallery i can put titles on

New phone with no gallery so i installed simple gallery which is nice.

But I use photos to remember things. It would be really helpful if I could add a title or something to a photo to help figure out what it is.

For example I took three pictures of the wiring under the dash of a car. It would be super useful if I could tag them? or some such, right left and middle so three weeks later I can look at those and know which is which.

It might seem like nothing but talking hundreds of pictures over years and several cars and boats.

The title doesn't need to be seen, I'm willing to dig for it if I need it

Any app that does this?
