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.

ScamShield: Your scam-fighting sidekick
ScamShield protects you by blocking scam calls, filtering scam SMSes, and letting you check suspicious messages before clicking anything regrettable.
Here’s what ScamShield can do:
[New] Get notified when a number you reported gets marked as scam-related
- When the authorities mark a number you reported as possibly used by scammers, we’ll send you a push notification. You can also view a history of numbers you reported that have been marked as scam-related.
Spot a scam before it gets you
- Came across a suspicious link, message, or phone number? Paste it in to see if it might be a scam. You can even upload screenshots - works for SMS, WhatsApp, and Telegram too.
Block and filter scam calls & SMSes
- Follow our quick setup guide to block known scam numbers and filter out sketchy messages.
Report suspicious calls, messages, and links
- Help the community by reporting scams - with screenshots if you have them. The more we know, the better we can protect everyone.
Heads up: Submitting a scam report in the app isn't the same as filing an official police report. If you've been scammed, please file an e-report with the Singapore Police Force.
Download ScamShield for yourself and your loved ones - because a little protection goes a long way.
We may occasionally prompt you to refresh the ScamShield app, which helps with performance and security. The prompt to refresh will appear when you open the app, and does not require you to visit the App Store to update to the latest version.
