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.

Eclipse Guide is a comprehensive and easy-to-use app for observing solar and lunar eclipses. It provides all information you need to experience and understand any eclipse of the past and the future.

*From the developers of famous astronomical app Star Walk, winner of the Apple Design Award 2010, loved by more than 20 million users around the world*

Main features:

  • Eclipse calendar with the list of solar and lunar eclipses of the past and the future.
  • Observing eclipses from the user's location, from any other place, or from the best location for observation.
  • Eclipse simulation with the play button to get a visual representation of the celestial event from its beginning to the end.
  • World map showing the eclipse path accompanied by the info about the sun coverage and the moon altitude.
  • The map illustrating the gradation of eclipse visibility.
  • The list of best places for eclipse observations.
  • Eclipse phases, timelines, and other core information.
  • Notifications about solar and lunar eclipses.
  • Share the information about eclipses with friends.

The app is not limited to upcoming eclipses only - you can choose any eclipse you want to learn about and view it at home or worldwide.

Advanced features:*

  • Audio guide with voice notifications won’t let you miss the desired solar or lunar eclipse. It will accompany your eclipse observation process providing comments on all the stages of the phenomenon.
  • Fullscreen informative maps show the visibility of an eclipse and its path. Use them to pick a good location for your eclipse observation. Zoom in and out, check the eclipse visibility for any location.
  • Star spotter simulates the sky at your observing location. Find out whether the eclipse will be visible from the selected location. Quickly identify and view solar and lunar eclipses in the sky.

The Star Spotter feature won't work for the devices that are not equipped with digital compass.

*Advanced features should be purchased separately (via In-App Purchase).

Remember: Looking directly at the Sun can cause serious eye damage or blindness. Never look at a solar eclipse without proper eye protection.

What’s new

Release notes for the latest version, as written by the developer.

v3.0.14

A deep partial lunar eclipse is coming on August 27–28, and Eclipse Guide is ready. At maximum, 96% of the Moon’s disk will be covered by Earth’s shadow, making it look almost like a total eclipse.

We’ve refined the calculations and updated the maps so you can check the eclipse’s visibility from your location, follow every stage, and see event times accurate down to the second.
