### 1/5 — Terrible

*2025-02-03*

This company screwed its customers by taking a free application and then making it a monthly fee. They jumped from the best option, to the absolute worst option. I don’t mind if they make this app a one time purchase, I’d even be willing to spend $100 on it. But I’m not paying a monthly fee just to possess an app. They don’t provide any monthly service, you have to provide your own details into the app. So they are literally collecting free money every month.

**Developer response:** Unfortunately we had to add monetization in order to keep improving the application.

### 1/5 — Von free zu pay

*2023-09-27*

Nie wieder, sehr schade

**Developer response:** Can you please share more details about what doesn't work for you?

### 5/5 — iPad could not push a full screen

*2023-05-15*

This is a great app. We love it. Only one issue.iPhone could push a full screen , but ipad not. Thanks a lot.

**Developer response:** Thank you! Can you please send more details at https://softvelum.com/mobile/help/ ?

### 1/5 — Cannot setup.

*2023-02-20*

The apple video explaining how to set this up is private and cannot be viewed. The video showing the button to stream does not explain how to make that button appear and the button never shows up. Cannot start stream because of this.

**Developer response:** Please check our docs reference here to learn more about launching screencasting under iOS https://softvelum.com/larix/docs/#iosscreencast

### 3/5 — Не работает

*2022-07-25*

Не получается передать видео по Srt с iOS устройства. В то время как с Андройд все работает. Broadcaster с iOS подружился, а скринкастер не хочет.

**Developer response:** Пожалуйста, отправьте чуть больше подробностей на https://softvelum.com/mobile/help/ , чтобы мы могли проверить проблему.

### 3/5 — No sound with SRT?

*2022-07-04*

Picture looks good when I stream to castr But there is no sound. I can use RTMP on other apps and I have sound

**Developer response:** Unfortunately iOS doesn't allow getting apps' audio, check Q23 in our FAQ https://softvelum.com/larix/faq/#q23

### 1/5 — audio error

*2022-05-18*

there is audio drop every second , please fix it.

**Developer response:** Please send us more details to https://wmspanel.com/help otherwise we don't have any details to fix the problem.

### 5/5 — Great!

*2022-01-19*

It takes a little while to figure out how it works, but after configuring it correctly its the best streaming application available for rtmp streaming. Gg to the developers!

**Developer response:** Thanks!

### 1/5 — Cannot connect

*2021-08-12*

I was looking forward to this program after using Larix broadcaster on OBS. Unfortunately the streamcaster just would not recognize obs when I try to connect. Keeps telling me it fails to connect.

**Developer response:** Please check your connections settings, it should work exactly the same as in Broadcaster.

### 5/5 — How to start stream

*2021-07-07*

Go to settings in ur iOS mobile or iPad then control center 
In there make sure screen recorder is in the shortcut.if not add to the shortcut panel by pressing plus sign.

Then drop down the shortcut panel in your device..then long press the screen recorder icon (icon looks like concentric circles)
It will show the list of apps capable of screen sharing…

Then select larix screencaster …after selecting..it shows ‘start broadcast’..that’s it…u can also enable mic if u need.

**Developer response:** Thanks for your review!
