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.
Strengthen your internal sense of rhythm.
Time Guru is the only metronome that periodically goes silent—randomly, in patterns, or both—so you discover whether you rush, drag, or lose your place.
Random & Pattern Muting
Set any percentage of random muting to test your timekeeping. Or create sequenced muting patterns. Or combine both. You'll quickly learn where your time falls apart—and strengthen it.
Complex Meter Sequences
Build unlimited chains of shifting meters: 4/4 -> 7/8 -> 3/4 -> 11/16 -> 4/4 -> 3/8. Meters go up to 16/x, patterns have no length limit, and you can rearrange them with drag-and-drop.
Gradual Tempo Changes
Automatically speed up or slow down over time—perfect for building technique.
Practice Timer
Set the metronome to stop after a specified duration.
Also includes:
- 35 loud, clear sound sets
- Drum machine-style rhythmic patterns
- Voice counting in English, Chinese, French, German & Russian
- Tap tempo (5–300 BPM)
- iCloud backup and sync
- Light and dark themes
- Full VoiceOver accessibility
- Rock-solid timing via custom audio engine

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.
