Five tacos is an understatement. This is the most impressive product I have backed on AppSumo. The updates have been constant, the service keeps getting better, and the value is incredible. The team is generous and passionate.

The App and the web version are both strong performers. I would love a white-labeled version of the app, but Heartbeat has been transparent in explaining the challenges, and I would rather have strong performance over a little more branding control.

I don't like Zoom. I understand it has a lot of support because of its API, but I want to use other services.

The embedding feature is excellent, but if I would like to see the option to somehow support whitelisted services over to the app. My limited tests show that works on the web version, but not on the app. This makes sense because the app is calling from a different domain.

Hearbeat can serve as a complete platform for a membership or community solution, or as a complementary part of something bigger. The content part of it is a little thin, but that is by design. It's meant to be easy to use on mobile. The conversation and notification aspect is very powerful, and it just works.
