HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (0.5 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Her sound

It’s not a bad story, but it would be enhanced if they had her make her familiar growling sound.

★★★★★Jul 3, 2014
Great for Dino lovers

My son (4 years) is obsessed with dinosaurs & he loves this app.

★★★★★Dec 31, 2012
Left Wanting

Decent but left wanting for price - no animation, few pages, solely focused on t-rex. Son finished in like 5 min.

★★★★★Jun 17, 2012
T-Rex

★★★★★Jun 14, 2012
Kind of boring

My son was not overly impressed.

★★★★★Jun 9, 2012
