Tap Tap Tap developer says 5% of Camera+ users make in-app purchases

So yes, says Tap Tap Tap boss John Casasanta, US$70,000 isn't to be sniffed at, but it still represents only 5 percent of Camera+'s 2 MILLION users using the in-app purchase facility to buy the $0.99 "I (heart) Analog" effects pack.

Well, whether or not you sniff at 70 grand depends rather on how much you earn elsewhere; Casasanta, in fact, has sold 2 million copies of Camera+ (currently on sale at $0.99 instead of $1.99) so, yeah, they can consider it small change.

However, the statistics he reveals on the company blog are interesting; half of all Camera+ users upgraded to the new version within six days, he says. And while the app was launched last summer (and then withdrawn because of the use of the iPhone's volume switch as a shutter release before coming back at the end of 2010), and its first million sales took, well, a while, the second million sales took only three months.

"If we were to stay on the same weekly pace that we're currently on (~160k sales per week), we'll get to 3 million in only 1.5 months from now," says Casasanta. And 4 million in three weeks, 5 million in the next 10 days and then a million a day, muahaha... perhaps he should buy a white cat to stroke to go with that cackle.

Seriously, Camera+ is a great app and the free 2.2 update adds many worthwhile features that we like here at TUAW. It's excellent to see them having such success.
