Google searches rising this week. Any one could point to your next app.

How this is counted

These are Google searches that rose this week, refreshed every Tuesday. A search stays only if the App Store can answer it: at least three of Apple's top results must match the words, and those apps must have real ratings. So the phrase does not have to say "app". We drop brand names and promo words. We also skip anything under 500 searches a month, because a big jump on a tiny number is not a market. The growth figure is Google's own, for the last 90 days. Breakout means it grew more than 5,000%. The line is how many people searched each month for the last year. Google rounds it, so we call it an estimate. Pick one and we count its market.
