How can I use OSM in a custom map app?

Hello, I'm a student working on a project right now, and I want to use OSM for it, but I'm not entirely sure if I can do what I need to with it/if I'm using the wrong tool for the job.

Basically, the project is a map app for phones (Android phones first, but iPhone compatibility would be an eventual goal) that shows specific locations with historical context in our area, and when those locations are clicked on it would show a photo of the location and some details about he history of the location.

This is where I thought OSM would be a good tool to use for the map, but I'm not sure how to proceed. I'm trying to figure out how this will work before I dive into making it, so what I'm trying to figure out is how (and if it is even possible if) I can have a version of OSM locally on the phone or on a server with custom locations pinpointed with its own metadata. I want to know if anyone knows if this is a good use case for OSM or if there would be a different solution I need to seek out.

Thanks so much for any help in advance.
