Why isn’t Stratus 3 working with my flight app?

Stratus 3 is compatible with Stratus Insight, Stratus Horizon Pro, ForeFlight Mobile, and other apps that use the GDL 90 protocol. To allow the receiver to connect to other apps, enable the Open ADS-B Mode switch in the Stratus Horizon Pro settings page. For a list of tested apps, visit www.appareo.com/stratus-3-compatible-apps.
