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.
Hark gives indie developers one place for notifications from all their projects.
Create a service in the Hark dashboard, copy its private webhook URL, and POST a simple JSON payload whenever something happens. Hark delivers the event to your iPhone as a communication notification with your project’s name and image.
Use Hark for:
- New signups and waitlist joins
- Payments and subscription events
- Failed jobs and operational alerts
- Customer feedback
- Launch milestones and anything else that can call a webhook
Each service can define a default title, image, and destination URL. Individual requests can override those fields when needed. Hark also includes idempotency protection, delivery activity, and secure token rotation.
One app. Every project. Let the important things find you.

Hark is now for teams.
Apps
- Open your own web dashboards and tools full-screen in Hark, already signed in. No passwords, no login screens.
- Your apps live on the new Hark home screen, grouped by team.
- Share an app with your team and everyone gets it on their phone.
Teams
- Create a team and invite coworkers with a link.
- Set roles for owners, admins and members.
- Team apps show who added them, and each person decides what they share.
On-call
- Set up rotations that hand off daily or weekly, in your time zone.
- Pages go to whoever is on call, then escalate if nobody answers.
- Acknowledge or escalate right from the notification. The first person to respond takes it, and it clears from everyone else's phone.
- See who's on call, your upcoming shifts and open pages at a glance.
Plus fixes and polish throughout.
