That being said, if you have built an iOS app then you probably know something about programming and are willing to travel that road.

The best place to get started would probably be the WordPress Plugin Developers Handbook

If you can map the wanted functionality into custom post types and related taxonomies, then you could potentially create those needed, add any extra meta boxes, etc.
