Every Door has a very confusing UI (lots of unlabeled buttons with unclear icons), unfortunately. I would love to use it, but even the web-based iD editor is so much easier to figure out!

You can choose the type of questions you want to get asked about in StreetComplete. If you want to only enter store names and timings, then go into Settings and pick those.

Have you tried out the Things or Places overlay? Second button from the right at the top, looks like a cake.

StreetComplete, as indicated by it's name, is about street data. Both are for contributing to OSM, but they are for different parts of OSM
