Ratings and reviews

Now features pick to zoom. The app is now perfect. It is suitable for professional use. The zoom is not fast enough for real-time zooming in live situations, but it provides a means to properly frame your shot. I no longer need to use external lenses. BTW, check out this company's other products and services. I have used on their wmspanel software and they are outstanding in quality and customer service.

I use the Larix app to stream Bible Study service on Wednesday evenings. The reviews I read previous to installing the app were fantastic. The app worked great for a few of our evening services but unfortunately, this past Wednesday was terrible! The audio feature is fine however, this picture resolution was nothing more than a blur. No one could see me at all. The entire screen was blurry. This is an issue that as of now, I still can't resolve. Need help before our next service!!!

I've used this now for a few weeks to stream our church service and have gotten positive feedback from people who have tuned in to the livestream. The only thing I would like to see is some indication of whether it is using the external mic or the built-in mic. I am feeding the sound to my phone from an aux port on our sound board and my Pixel 3a does not always detect the line plugged into the headphone jack as a microphone. So, the only way to tell is by monitoring the livestream on a separate device to see what it sounds like. It would be nice if there was some way to indicate which mic was being used for the audio. Or, a setting that forced it to use ONLY the external mic (rather than use external mic if available). Then, if I am not getting any sound level indication on the screen, I would know that it is not detecting the external mic. Thanks for the great app!
