This guide explores various iOS apps for live streaming to an RTMP server, providing insights into their usability, cost, and features such as support for RTMPS and portrait orientation. The author, who has no affiliations with the apps, emphasizes the importance of security through RTMPS, which Facebook now requires, though many apps surprisingly lack this support. Wirecast Go and Larix Broadcaster emerge as top recommendations, with Wirecast Go praised for its production capabilities despite lacking RTMPS support, and Larix Broadcaster lauded as the best free option, supporting both RTMPS and portrait mode. Other apps like Broadcast Me and It's My Live offer varying features and limitations, such as the need for account creation or lack of portrait mode support. The guide also notes the challenges with some applications, including technical issues and hidden costs, while prompting readers to share their experiences with different apps.
