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.

Ein stabiler Rumpf gilt als Grundlage für eine gesunde Körperhaltung und ist essentiell für die Kräfteübertragung im Alltag und im Sport. Physiotherapeutinnen der Uniklinik Balgrist haben aus den bewährtesten Rumpfübungen ein effizientes Zirkelprogramm zusammengestellt. Dieser sogenannte Rumpfzirkel besteht aus einer Reihe von Übungen, die den Rumpf kräftigen und stabilisieren sowie Muskelspannungen regulieren.

Für das unkomplizierte Training wird nur eine Gymnastikmatte benötigt. Schon 10 Minuten regelmässiges Trainieren wirkt effektiv auf die Rumpfkraft.

Die Rumpfzirkel App lässt ein iPhone, iPod oder iPad zum motivierenden Trainingspartner werden. Los geht’s!

Funktionen:

  • dem aktuellen Fitnesslevel entsprechende Übungsauswahl
  • Fotos und Videos zu jeder Übung
  • Integrierte Stoppuhr
  • Individuell anpassbare Übungseinstellungen
  • Gleichzeitiges Abspielen der persönlichen Musiksammlung
  • Trainings-Logbuch
  • Rumpfzirkel Community auf Facebook
