Sure, why not? The main one's I've seen that have come to mind are editors. but there isn't really any limits to what you can make. Did you have something you had in mind?
My brother gave an idea of a "beertender". Like an encyclopedia of beers from all over the world and one of the main features, besides the complete info, is to id the beer by Just taking a picture of the label. Besides that, i'm still thinking something that would require Just a simple dropbox/googledrive storage for the database. Like an Excel file that i could convert to an array.
Edit: what editors? Could you link one?
