Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
Let's face it, there are a lot of developers who like the idea of an issue tracker, but find it too much effort to use & maintain for solo, indie or hobby projects.
Enter Scarlet. Scarlet is a personal issue tracker that saves to a file that you can include in your project directory, or anywhere you prefer. No accounts, no cloud services, no syncing, no third-party integration. Just a simple place to file away your project's to-dos and close them when they're complete.
Add tags to an issue to help organize things, and that's it — it really couldn't be simpler.
