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.

Phone running slowly, charging slowly or low brightness? See if your device is overheating using Thermals.
Thermals displays your device’s thermal state, as well as how many processors are active on your device and its uptime, as reported by iOS.
Thermals helps troubleshoot:
- Poor performance — iOS reduces processor speed and potentially disables processors temporarily when the device is hot.
- Slow charging — battery charging causes a lot of heat and iOS can limit charging speed to reduce the additional heat that might make a device too hot.
- Low maximum brightness — if your device screen stays dark despite being on full brightness, it could be limited by iOS due to heat.
- Manufacturing defects — if not all processors are active when the device is cool and not in low power mode.
Your device's thermal state is monitored regularly in the background and recorded in the app (if Background App Refresh is enabled). Open the app or tap the widget to record a data point manually.
Export the raw data to file for corroboration with Screen Time, Xcode's Instruments, or other development tools.
Also an independent Apple Watch app shows the thermal status, active processors and uptime, and thermal history of your watch.
