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.

Coucou is the iPhone companion of Coucou for Mac, the little friend who lives in your MacBook's notch and keeps an eye on your AI coding agents: Claude Code, Codex, Cursor, Gemini CLI and more.

SEE YOUR SESSIONS
Every agent session from your Mac, live: what it's doing, its plan step by step, its last message. The most urgent one first.

ANSWER FROM ANYWHERE
When an agent needs your permission, you get a notification with the exact command. Deny it right from the notification, or allow it with Face ID. Your Mac only applies a decision meant for the exact request it is waiting on, and requests expire after 2 minutes.

MOCHI IN YOUR DYNAMIC ISLAND
Lock your Mac while an agent works: Mochi moves to your iPhone's Lock Screen and Dynamic Island, and comes back to the notch when you unlock.

WIDGETS
Solo, Team and List on the Home Screen, and Mochi on the Lock Screen.

PRIVATE BY DESIGN
No account, no analytics, no ads. Your sessions travel through your own private iCloud, with project names, commands and questions encrypted with your iCloud keys.

Requires Coucou for Mac with Settings → General → iPhone turned on, and the same Apple Account on both devices.
