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.

WHAT IS IT
TransKey is a keyboard extension that translates your messages inside any app (like: WhatsApp, iMessage, Facebook, Twitter X, Email, Chat Apps, SMS, and many more).

TransKey also works the other way around. Copy the text you can't understand and TransKey will show you what it means in your native language!

HOW DOES IT WORK

Write what you'd like to say, but before sending your message, tap and hold the Globe key to switch to TransKey. After selecting a target language, tap "Translate text" and watch your message get translated right in the app!

If you'd like to translate a message you received, tap and hold it until an option to "Copy" appears. In TransKey tap "Translate copy", and the translation will appear in the same place!

Never encounter another language barrier again when communicating with people in other countries! TransKey provides a flawless translation experience right in the messaging app of your choice unlike other translators which interrupt the flow by forcing you to switch to another app.

Unlike other translator keyboards, TransKey does not have a keyboard for typing. This allows you to use the keyboard you're most comfortable with, such as the iOS, GBoard, or SwiftKey.

NOTICES
For accurate real-time translations, TransKey relies on industry leading machine-translation engines such as Google Translate, Microsoft Translate, and Yandex Translate. AI translators are not used in this version.

You will need to grant Transkey full access for it to work properly. They keyboard will need to get the text you type so it can send it to the translation service. We do not store anything you translate. See the Privacy Policy.
