HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (5.3 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.

Best calendar app

I love the little stamps to mark dig occasions at a glance! I just wish Apple would add stamps like this. This app is easy to use as well as fun and has many cute visuals.

★★★★★May 29, 2015
Love it

I love this app . The only reason it's not 5 stars is they don't have an English language version .

★★★★★Nov 2, 2014
Great app, but...

This is exactly what I was looking for! However, I only understand English and Spanish. I would love if you could add either of those languages to the app. I think you'll have more people download it as well if that were to happen.

★★★★★Nov 1, 2014
.

This app needs to be in English also

★★★★★Jul 3, 2014
