Great App For Streamers

I’ve been using this app for over a year now and it is very easy and simple to use! I’ve been using it with an Apple Watch and it seamlessly connects with my stream by providing my real-time heart rate for the viewers of my stream to see. The instructions aren’t tedious and honestly it is worth every penny since there is no additional payments or fees required for its intended use.

Even a year or so after purchase, the developers of this app are still putting in the work to improve the customization options available within the app.

Overall, if you want to add an interesting aspect to your stream or videos, download this app. It’s cool seeing your chat react to your heart rate in intense situations on stream.

It’s a very good app. I hope more features are added.

It just works. Once you set it up you just hit the connect/disconnect from the app on your watch. I have zero issues with it updating my heart rate on my OBS browser source.

I had purchased a Garmin Instinct E-Sports edition to thought better of it. Found this app. This works even better for heart rate and you don’t have to pay for another watch or other hardware.

I would love to see more features added similar to the Garmin like stress and body battery estimations but for heart rate this is app does it’s job and it does it well.

Best For Streaming!!

I was playing a horror called MADiSON and I was using my actual camera to monitor my Apple Watch series 4 stainless steel so it looked a little scuffed. A viewer of mine told me that there were heart monitors for OBS. So I was browsing and saw this app. I was so nervous about but I said what’s the worst that could happen. Bought the app and it worked right away! HIGHLY RECOMMEND IT!!
