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.

Chordbot lets you create and play chord progressions in different styles easily. Just add chords, select instrument tracks and hit play.

Experiment with complex chord progressions without having to master an instrument or music theory first. Great for songwriting experiments or to create your own backing tracks for instrument practice. Easily create arrangements and mixes by selecting from hundreds of piano, guitar, synth, bass and drum tracks.

This is the full version of Chordbot with all features enabled. There is also a free evaluation version (Chordbot Lite) with disabled save/export features that you could/should try before buying the paid version.

Features:

  • 60+ chord types

Including classics like AugAdd2 and Min7(#11), in all inversions.

  • 70+ comping style presets

Simple but usable arrangements that won't get in your way.

  • 400+ instrument tracks

Individually mixable dynamic instrument tracks that can be combined to form unique comping styles.

  • Inversion control / slash chords

Manually select chord inversions, or let Chordbot select the smoothest inversion automatically.

  • Song sections

Songs can be structured into repeatable sections (verse, chorus, etc). Each section can have its own comping style/arrangement.

  • MIDI/WAV export and background playback

Refine your compositions in a DAW/MIDI sequencer or play along with a virtual instrument

  • Song-O-Matic

Automatic song generator with pop, jazz and experimental profiles.
