Thanks, yeah I should have clarified. I would like to easily edit OSM on android :)
http://vespucci.io/ is active developed and pretty powerful. For simply adding opening hours or a phone number I use https://maps.me/download/ (iOS, Android).

I think maps.me is one of the few apps that are easy to use and contribute to OSM. Unfortunately there was some controversy, because maps got vandalized or filled with trivial/garbage data, because user didn't understand that their notes ended up in a public database.
StreetComplete is a very nice, targeted OSM editing app
That being said, I don't know of a similarly easy to use editor on Android for simple things like adding opening hours or addresses.
