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.

pingrb is a tiny push notification app. Webhooks, monitoring alerts, and CLI pings from any agent or shell script turn into clean push notifications. No code to write. No services to host.

If it can POST, pingrb can push.

Built-in sources:

  • Stripe (payments, refunds, disputes, subscription events)
  • Cal.com (bookings, reschedules, cancellations)
  • Hatchbox (failed deploys)
  • StatusCake (site down, site up)
  • Custom curl endpoint (anything that can POST JSON)
  • pingrb CLI (Claude, agents, shell scripts, cron jobs)

How it works:
1. Sign in at pingrb.com (free).
2. Pick a source. Copy the webhook URL or curl command.
3. Pushes arrive on this app instantly. Tap any push to jump to the source.

CLI install (free, Homebrew):
$ brew install ruby-native/tap/pingrb
$ pingrb "deploy finished"

One price, no subscription. Pay $9.99 once for unlimited pushes. No monthly fee, no per-notification cost, nothing to self-host.

Built by Joe Masilotti, author of "Hotwire Native for Rails Developers" (Pragmatic Bookshelf).
