HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (45 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. 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.

Finally!

Finally they launched the app. Have been using the website for the past couple months and loving the content. In addition to the content, the quality of the website and the app should tell you these guys know what they’re talking about.

Great companion for interview prep

Really useful app for keeping up with technical interview prep on the go. Great for reviewing concepts, reinforcing what you’ve learned, and making productive use of small pockets of downtime. The content is clear, well-organized, and easy to follow. A great companion to the Hello Interview website.
