This app has constantly been my “go to” app for streaming RTMP from my phone. It has solid features, it is reliable, and easy to use. I have recommended this app to many people over the years, as I use this technology almost daily.Recently, I’ve been watching as each update takes away standard features and puts them behind a rather premium subscription - $9.99 a month or roughly $120 a year. Most recently, a limitation was added to free streaming to your own self-hosted endpoint. My streams are usually about two hours long and would be cut off.While I completely understand needing to make profit on one’s labor, I cannot justify spending that kind of money on this product when there are other capable apps that allow free streaming and pay-once-for-the-feature upgrades. Furthermore, slowly taking away features that were already part of the app’s free offerings and placing them behind a paywall, in my opinion, is not good. The app is great and functions well (5 stars). The pricing scheme has forced me to look elsewhere (-2 stars).

Thank you for sharing the extended review. Our team had to move to monetization model for the features used by advanced streamers, hence the in-app subscription. Thank you for supporting us.
Getting worse and worse… Been using the app for over a year

UPDATE: I did update to your new version from 2 days ago, and the rotation bug is NOT fixed for overlays on PREVIEW, which I use extensively to read live chat and alerts! Its still upside down on preview and only right side up on the live end feed. Please test your product because its frustrating having to pay subscription for the product and be your QA as well. I use the software 5 days a week and this has been broken for 2 versions now, I can now only broadcast without live rotation mode until this is fixed… very frustrated.Had no problem with paying monthly fee except now there are more bugs than ever!! Latest bug makes overlays upside down when using live rotation mode, is there anyone even testing this app before releasing new versions? Not to mention it now crashes freq and does not support srtla … it was a good app I will give it one more week to fix the upside down overlays before deleting and cancel my monthly sub.

Was an amazing app until they decided to paywall free streaming and watermark your stream
Jonathan.Colon
Great features! Best live streaming app out there especially for twitch IRL from an iPhone. until recently you could go live as long as you wanted no issues. Now if you stream over 30 minutes they place an ugly watermark over your stream unless you pay them 9.99 a month. This is unacceptable especially with the lack of a manual and explanation of features. I googled “audio engine Larix” to see how this feature works and there is little or no information explaining most of the features in the app. They also offer ndi streaming for $20 and fail to explain what the feature provides. Do I no longer need a server to push my feed to OBS if I use NDI over cellular data? That’s the only way I can justify paying $20 a month since servers cost money. I am confused. Maybe work on some documentation for your software then start charging for basic features that were already free.
Developer Response
Thank you for sharing. We'll add more clarification for NDI support to remove confusion.
Solid Streaming App

As someone who works with multi-million dollar streaming encoders for a living, I have to say that this app was fantastic. I had a small wedding to stream over the weekend for a friend of mine so I decided to try this app. I got a month subscription, plugged in an external audio interface (Scarlett 2i2) and ran the stream with great picture and amazing audio. Paired it with a solid fluid head tripod and a MagSafe tripod mount and it was a dream setup. I do want to add that I had poor service where I was, around 2 Mbps upload over cellular on all three carriers and no WiFi. This caused a few dropouts but nothing the app could’ve done differently. I recorded a continuous high bit rate version for the family to share. This was a life saver!
