The OpenStreetMap editing code (OSMEditKit) is the app's own, under the EUPL-1.2. The iPhone version also uses Apple's own iOS frameworks (SwiftUI, Core Location and others). Every iPhone app depends on these.
Full component record
The repository contains COMPONENTS.md, a complete record of every library, data
source and service the app uses, with version, licence, organisation, hosting and whether it
depends on American parties. This page is a summary of it.
