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 app includes the following ear training exercises:
Intervals: In this exercise, you will hear two notes in sequence. Your goal is to identify the interval between the two notes.
Chords: In this exercise, you will hear a chord. Your goal is to identify the type of chord that you heard.
Scales: In this exercise, you will hear a scale. Your goal is to identify the name of the scale that you heard.
Chord Progressions: In this exercise, you will hear a chord progression. Your goal is to identify each chord that you heard.
Perfect Pitch: In this exercise, you will hear a single note. Your goal is to identify the name of the note.
Scale Degrees (functional): In this exercise, you will hear a short chord progression followed by a single note. You must identify the scale degree of that note relative to the key established by the chord progression. This is also known as "functional ear training".
Intervals in Context (functional): This exercise combines the "Intervals" and "Scale Degrees" exercises. In this exercise, you will hear a short chord progression followed by two notes. You must identify the major scale degrees of the two notes relative to the key established by the chord progression as well as the interval between the two notes.
Melodic Dictation: In this exercise, you will hear a short chord progression followed by a short melody. You must identify the major scale degree of each note in the melody.

Is this US chart app missing in UK?
It showed up on a UK chart in the last 30 days, so it is not a gap.
Store not checked yet
This is a candidate, not a verdict. Charts show at most 100 apps, so not charting does not mean no demand. Check the UK store before you decide.
