App to modify OSM

Is there an App to draw or realize changes in OpenStreetMap ?

Vespucci is a full blow editor.
OsmAnd, a navigation program allows you to make (smaller) changes as well.
StreetComplete has a number of quests that asks to complete missing information such as street names, road surfaces, house numbers, opening hours, etc.

See in the OSM wiki for another oveview of OSM related apps.
