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.
The foremost field guide to Australian birds is now available on the iPhone, iPod Touch and iPad with a comprehensive collection of bird calls.
** If you would like to experience the app check out The Michael Morcombe eGuide to the Birds of Australia LITE which is FREE and includes 59 species **
Michael Morcombe’s Field Guide to Australian Birds has been called the most comprehensive field guide to Australian birds in the market today and now it is perfectly complimented by the eGuide which features:
- iPhone optimised controls – swipe to next or previous species, one-tap enlargement of an image and rotate the device (landscape) to enlarge an image completely (and fit the width of the screen).
- Over 3000 hi-res bird images covering over 790 bird species.
- Most bird species have a detailed distribution map showing any subspecies that occur.
- Detailed text descriptions of almost all bird species including songs and calls, measurements and breeding behaviour.
- Over 1800 carefully-selected and edited sound recordings for over 600 species. Many species are represented with multiple call examples showing the full range of vocalizations.
- The ability to compare any two images, maps, or sounds, side by side on the screen. The ability to filter by geographic location, so that you see only the species likely to occur in your location, and to further reduce the possibilities to usual or vagrant species in the selected area.
- A “Smart Search” that gives the ability to search by distinguishing features such as size, colour, physical features, habitat and exclude certain types of birds (eg. Passerines).
- A basic personal species list that stores your sightings saved to the device* (ability to upload list coming soon)
- A comprehensive help and introduction section to help you if you get stuck or don’t understand how a certain feature works.
*Uninstalling/reinstalling the program will result in the loss of your list, it is recommended that you keep your own backup (master list) separate from the application.
