This app is unusable unless you subscribe... This was a cute little app I could use as an extension to my stream when I had to step away from the PC, but now with the huge noticable text that cover the screen I will be deleting looking for another app .. hey here's a suggestion why not have the subscription for people who can pay and maybe cut down the broadcasting time for none subs but the text on screen is ridiculous... I wouldn't subscribe just because of how ridiculous it is.

We're sorry but this is necessary to keep the app sustainable. This allows us to develop advanced features and keep high quality of the app.

Decent app. Unacceptable change to a subscription service. I would be willing to purchase a lifetime license, but I will NEVER pay 9.99 a month. For such an app as this, a monthly subscription is totally unreasonable at any price more than $1/month. You're also more expensive than a competing app that offers more. I can obtain a much better streaming app with many more features for $80/yr. I'm very sorry you decided your product is worth more than it is.

We had to add monetization unfortunately to keep the development on the same good level as we described here

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.
