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.

TRUSTED BY PROFESSIONALS FOR OVER 70 YEARS.

---iStroboSoft for iOS---
Peterson Strobe Tuners' popular StroboSoft tuning application for iPhone and iPad. iStroboSoft™ offers the unmatched accuracy of a mechanical strobe tuner for the highest degree of precision available in a software tuning application.

Plug in and tune your electrics and acoustics quickly and easily with 1/10th cent accuracy.

Peterson Tuners has offered tuning solutions for over 70 years and is the only company specializing in hardware and software tuning products for all levels of musicians.

FEATURES:

  • Stand-by mode to reduce battery usage or freeze the display.
  • Guided Mode Tuning offers an alternate strobe display that slows the strobe bands one-by-one as you come closer to tune.
  • Speed control for strobe display; dampen the response for a longer note display.
  • 12 Temperaments with adjustable root control.
  • Display all sharps note display.
  • Assisted Low Note Detection (ALND) helps capture very low frequencies.
  • Mains hum filter option reduces the chances of the tuner latching on to 50 or 60Hz cycle hum when using a direct line-in connection or while using the app during device charging.
  • Smooth, real-time strobe display allows you to achieve an unmatched level of accuracy.
  • Note/Octave window displays the correct note and octave for the note being tuned.
  • Cents display allows you to see how far out of tune your note is in cent values.
  • Tune in auto or manual mode.
  • Toggle the display to show: cents, Hz, MIDI note value for the note being tuned.
  • Glowing flat/sharp indicators assist when tuning a note very far from the target position.
  • Noise filter: Use the noise filter when utilizing an external mic or clip-on tuning device to help reduce the effect of extraneous environmental noise during tuning.
  • Input boost: The input boost will raise all input frequencies by +24dB.
  • Calibration mode: iStroboSoft can be calibrated to an external source guaranteeing 1/10th cent accuracy.
  • Drop/Capo mode: iStroboSoft will auto-transpose notes up or down to one full octave.
  • Adjustable Concert A: Change the Concert A reference of the tuner to accommodate tuning to a fixed instrument, such as a piano, or tune instruments that do not utilize the typical Western A440 reference.
  • Full screen mode permits the strobe display to be maximized on screen to allow better viewing from a distance.
  • Change strobe display colors to accommodate different lighting environments or set a preferred user color for those with limited color palette recognition.

Use the built-in mic on your device for tuning or connect directly via the headphone jack using an approved adaptor cable or interface.

Devices without a headphone jack can connect a pickup or mic using the lightning-to-audio adaptor.

How the score works

Gap check · UK

Is this US chart app missing in UK?

Already on UK charts

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.
