Tap Tap Tap always does a great job being open with their successes and failures.

I was pumped, and we were ready for the app to leap out of the gate. For some background: The Heist sold 89,689 units on its first full day of sales. Camera+ 2.0 sold 47,989 units on its first full day when it was relaunched. The partnership with Tapbots for Calcbot produced a first full day sale number of 11,979 units sold.
