What Blockstream app (Green) is
The Blockstream app, formerly Blockstream Green, is a self-custodial wallet for on-chain Bitcoin, Lightning and Liquid assets on iOS, Android, Windows, macOS and Linux, made by Blockstream Corporation Inc.

Bitcoin can be bought inside the app through exchange partners, which are not named on the page and apply their own terms. The code is public under the GPL-3.0 licence.
