Application Usage Rules of Thumb

"One fairly common 'law of web and mobile physics' is the ratio of registered users or downloads to monthly actives, daily actives, and max concurrent users (for services that have a real time component to them), says venture capitalist Fred Wilson. "I call this ratio 30/10/10 and so many services that we see exhibit it within a few percentage points here and there."

What Wilson sees is that, for most providers, 30 percent of the registered users or number of downloads (if its a mobile app) will use the service each month. About 10 percent of the registered users or number of downloads (if its a mobile app) will use the service each day.

The maximum number of concurrent users of a real-time service will be 10 percent of the number of daily users.
