TestFlight Live is a real-time dashboard for iOS apps, sort of like Chartbeat for app data. It shows live engagement, revenue, audience, and stability information on one website. It allows developers to see how their apps are selling, and how well their in-app purchases are doing. It also allows them to see how well their in-app ads are doing, though this isn’t exclusively tied to Burstly at all. It even shows the all-important Revenue Per User RPU.
