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.
Elfer Atlas is an independent reference for anyone who loves the 911 – from the very first car in 1964 to today's 992.
EVERY GENERATION
Eight generations – the original 911, G-series, 964, 993, 996, 997, 991 and 992 – with 230 variants. Each variant lists model years, body styles, engine, engine code, displacement, power, torque, gearbox, drive, acceleration, top speed, weight and production numbers where sources exist. Uncertain values are shown as ranges and unknown data is clearly marked.
SEARCH AND COMPARE
Find a model in seconds, and compare two variants side by side. The best value in each row is highlighted.
MY CAR
Add your own car – or several – with your own photo from the camera or photo library, nickname, model year, colour, mileage and registration number. Pick the model from the list or find it with the chassis number.
SERVICE BOOK WITH REMINDERS
Log services, repairs, parts, tyres and inspections with date, mileage, workshop, cost and a photo of the receipt. The app reminds you when the next service or inspection is coming up.
VIN DECODER
Enter the chassis number to see generation, model year, plant and likely variants – decoded locally on your phone.
