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.

Caustic 3 is a music creation tool inspired by rack-mount synthesizer/sampler rigs.
Everything is real-time and optimized for mobile devices.

Create your rack by adding up to 14 machines from a choice of:

  • Subsynth - Virtual analog subtractive synthesizer
  • PCMSynth - Multi-sample wave synthesizer
  • BassLine - 303-like monosynth
  • BeatBox - 8-channel sampling drum machine
  • PadSynth - Harmonic table pad synthesizer
  • 8BitSynth - 8bit equation solver synthesizer
  • Modular - Fully configurable and routable synthesizer
  • Organ - Tonewheel organ with rotary speaker
  • Vocoder - 8-band harmonic vocoder
  • FMSynth - DX-style 3-operator fm synthesizer
  • KSSynth - Karplus-Strong string modeling synthesizer
  • SawSynth - Supersaw-type synthesizer

The app also includes:

  • Effects rack supporting 2 effects per machine (20 effect types).
  • Mixer desk with EQ, panning and global Delay/Reverb effects.
  • Master section with effect slots, parametric EQ and limiter.
  • Song sequencer

AudioBus support for Input and Output slots.
AudioCopy Paste + AudioShare support for import and export.

Supports automation recording on most controls and includes powerful editors for modifying automation curves.

Users can record their own WAV files for use in the PCMSynth, BeatBox, and Vocoder or import files through iTunes file sharing, ACP, AudioShare, or the built-in FTP server.
Supports all uncompressed WAV files (8-16-24-32bit, any sampling rate).
The PCMSynth can also load SoundFont files (.sf2), SFZ and FL/Xewton instruments (.instr, .ZIP)

"Open In.." import support for all preset types, .WAV, .SF2 and .MID.
(MIDI (.mid) files can be imported as raw sequencer note data.)

Supports CoreMIDI and virtual MIDI for note, velocity and CC data. (be sure to set "Enable background audio" in advanced options to use virtual MIDI)

See the in-app help section for dozens of informative tutorial videos and full online manual.

There is also a FREE (full version) PC/Mac version available for download on the product website.
