How native applications can link[1]#
A separate (but complementary) feature coming to both Android M and iOS 9 is an improvement on how native applications can link between themselves, and their associated web servers. Both Android's App links

The Native Applications Working Group (NAPPS) WG in the OIDF is in the process of discussing the impact of these new mobile OS features on the emerging NAPPS spec. Apple's Universal Linking and Android's App Links both appear to provide a meaningful security enhancement and so it may make sense for NAPPS to stipulate their use. ... Again, in the context of a native application getting the user authenticated against an OAuth AS, the new linking mechanisms promise to provide additional assurance that the tokens are being issued to a valid application, and not some malicious application that was able to get itself installed and squatting on the valid custom scheme URLs. (The Proof Key for Code Exchange by OAuth Public Clients (PKCE) mechanism was motivated by the same risk, though PKCE allows the AS to ensure only that the tokens were returned to the particular application that requested them, which could be a bad app).
