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.
Sight-reading skills open the door to reading written music and familiarizing yourself with various music styles. Sight-reading is not a daunting task, and with sufficient practice, anyone can develop this valuable skill.
Our app is designed to help you quickly identify notes across every part of the fretboard, with a special focus on positional playing.
By enhancing your sight-reading abilities, you'll find it easier to focus on other musical aspects like harmony and rhythm.
Features:
PRACTICE & TEST MODE
- Four different modes of use:
1. Locate notes on the fretboard based on the notes in staff.
2. Locate notes on the fretboard based on note name and pitch.
3. Find the names of notes on the staff (without the fretboard)
4. Identify the names of notes presented on the fretboard.
- Automatic detection of problematic notes.
KEY SIGNATURES & SCALES
- Key signature support, from 1 to 6 sharps or 1 to 6 flats.
- Automatic selection of the enharmonic notes for each scale to prevent double sharps or double flats in the key signature.
- Scales include major, minor, melodic minor, harmonic minor, blues, pentatonic, and all modal scales.
FRETS, STRINGS & NOTE SELECTION
- Frets are grouped to limit the number of notes to practice and test.
- Predefined fret groups, e.g., 0-3, 4-6, 7-9, 10-12, 0-12, 13-17, etc.
- You can define custom fret groups.
- The highlighted fret group is displayed on the fretboard.
- Your sight-reading progress is tracked per fret group.
- The longest streak record per fret group measures your sight-reading accuracy.
- You can select specific strings for the highlighted area.
- Test notes can be limited to naturals or notes from a selected scale.
READ AHEAD
- Reading ahead is a crucial skill for effective sight-reading.
- You can adjust the number of notes to read ahead.
OTHER
- More than 15 alternate guitar tunings e.g., drop D, NST (new standard tuning) and all fourths tuning.
- Support for left-handed guitars.
- Option to display the fretboard in perspective (in landscape mode).
- A universal app compatible with iPhone, iPhone Duo, iPad.
- Supports all screen sizes.
- No ads or in-app purchases.
- Dark mode support (iOS 13+).

What’s new
Release notes for the latest version, as written by the developer.
Important fix for iPadOS 26.6 users: Resolved a startup crash caused by an iPadOS function for determining screen safe areas that behaves differently in iPadOS 27. The app now uses an alternative approach.
Additional layout refinements for the iPhone Duo.
