HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (123 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.4 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.

Recognition of the input

This is just a feedback, hopefully the developers can see it. Words like 焼き肉should be marked correct when typed 焼き肉or焼肉. The problem is in different problems while the answers are technically the same, but only one of these inputs is correct. What made it worse, 焼肉 can be answer for one question, and 焼き肉is the answer for another question, and they aren’t interchangeable. There are a few more questions and words like this situation. Would be nice if devs can do something about it

Crashes

I really wish I could rate this higher but it’s been crashing pretty consistently for the second lesson. Idk if it’s an error with something for the voice recognition or something to do with the store level.
