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.

This is the most feature packed Sabbath School quarterly on the market. Use it to enhance your lesson study. This is the app for true lesson study. It is the only Sabbath School app with these exciting and useful features:

  • You can highlight portions of text, so they pop out in Sabbath School.
  • You can write notes just like in the paper copy.
  • Notes and highlights can sync between your devices.
  • Bible references are turned into weblinks for quick viewing.
  • The teachers edition for the week can be viewed with a simple click.

Sabbath School Quarterly app allows you to take your Seventh-Day Adventist Biblical studies wherever you bring your phone. Most Seventh-Day Adventist churches teach on the same topic or reading in a given week, as each quarter of the year has a different theme that reflects Bible, doctrinal, or church lifestyle teachings. Thus the lesson booklet is called quarterly.
This app provides you with all of the Sabbath School quarterlies for the current and previous three quarters. It lets you take notes, and it remembers the notes for later when you are taking part in the discussion during Sabbath school. The app allows you to hone in on the specific week and day of study and enables you to move from one day to another with a tap or swipe of your finger.

The SDA Sabbath School Quarterly App is an independent ministry that supports the mission of the Seventh-day Adventist® Church; however, it is not part of, affiliated with, or supported by the General Conference of Seventh-day Adventists® headquartered in Silver Spring, Maryland or any of its affiliates known as the Seventh-day Adventist ® Church. Thus, any content or opinions expressed, implied or included beyond that included in the Seventh-day Adventist Quarterly are solely those of the creators or owners of the SDA Sabbath School Quarterly App and not those of the General Conference or the Seventh-day Adventist® Church.
