### 1/5 — defective

*2026-07-14, version 1.8.5*

Defective app can’t stream due to clunky stream key and poor url detection. Absolutely written by a potato

### 1/5 — Paywalled Garbo

*2026-06-22, version 1.8.3*

Pay up or face a big watermark lol what a joke

### 5/5 — David Visuart aqui

*2026-06-20*

O app é muito bom!! Muito completo não sei se tem sistema de replay que eu preciso para transmissão! Mas é uso e recomendo app excelente quase perfeito. Quando  adicionar replay no aplicativo vai ficar bem melhor ao vivo e vídeos ao vivo de propagandas vai ficar mais perfeito! Excelente app parabéns aos idealizadores.

**Developer response:** Thank you! Can you send us your feedback here?  https://softvelum.com/mobile/help/

### 1/5 — Ridiculous

*2026-02-17, version 1.7.5*

Having to pay a monthly subscription to stream to your personal server is pure greed.

### 1/5 — Через rtm не работает

*2025-08-01*

Я стример больше 4лет после того как одна программа стала платная решил посмотреть эту программу) с меня за месяц сняли 1000 рублей в итоге картинка хуже чем в призме, хдр не работает, после часа стрима трансляция перестала работать, попробовал через стримить через сервис стреam vi постоянно вылетает. Стримил через rtm ссылку. На ютубе 21к подписчиков все просто смеялись вчера от таких танцев с бубнами. У меня вопрос за что такие деньги вы берете? На вашем ютуб канале непонятные гайды попробовал найти других блогеров и гайды по вашей программе их просто нет 😂 для простых стримеров как я с ютуба не рекомендую эту программу

**Developer response:** Сожалеем, что в ващшем случае прложение работало со сбоем. Пожалуйста, напишите подробнее на https://softvelum.com/mobile/help/ параметры потока и настройки, мы перепроверим у себя.

### 5/5 — Solid Streaming App

*2025-05-27*

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!

**Developer response:** Thank you so much for the detailed feedback! We build this app for all kinds of use cases and hardware, and yours is just amazing. Thanks!

### 1/5 — Broadcasting to rtmp

*2025-05-27, version 1.7.1*

With WiFi conning to my local host, rtml still drops out its connection. No errors.

### 3/5 — Thx for app

*2025-05-16*

"Larix Broadcaster is a free mobile broadcasting software for iOS…" - that's what the official website claims. But unfortunately, that's only half the truth. The full truth? Want to stream? Want to stream without the 60-minute limit? Then pay up. It really used to be completely free before.

**Developer response:** All payments support our development team to keep the app the best in its class. Feel free to support us any time by subscribing.

### 1/5 — Ridiculous Pricing

*2025-05-08*

I have no issue with paying for good software, I even prefer it over the freemium / ad method. But for what this app does it’s hard to justify the cost. The watermark  covers the entire screen and the time limit basically makes this a demo app unless you pay $10/mo or $120/year. Those are the only options. 

Would be great if the dev introduced a more limited feature set for people that simply need a singular feature. I’d happily even pay an annual subscription at a more reasonable price to unlock non-watermarked RTMP streaming without a time limit.

PRISM LIVE isn’t as feature rich but it’s very reliable and you get a usable RTMP streamer at no cost with only a very tiny watermark in the corner and no time limit.

**Developer response:** Your payments support our development team to keep the app the best in its class. It's indeed the most feature-rich solution so if you need to work with sophisticated use cases, please feel free to come back any time and subscribe for as long as you need to use it.

### 1/5 — Doesn’t seem usable as rtsp streamer.

*2025-04-27, version 1.6.9*

When using as rtsp streamer, should take ip of phone. Doesn’t seem setup correctly for this. Other more basic apps work with 1 click. This is all I needed maye app simply isn’t for me.
