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.

Pressure4U turns your iPhone’s rear camera and flash into a fingertip wellness scanner. Using photoplethysmography (PPG) and AI-assisted signal analysis, the app estimates heart rate, oxygenation trends, and blood-pressure trends in about a minute—no cuff required for a quick check.

HOW IT WORKS

  • Place your fingertip over the rear camera that lights up with the flash
  • Follow the 5-second countdown, then hold still while Pressure4U reads your pulse wave
  • See heart rate (BPM), SpO₂-style oxygenation, and systolic/diastolic estimates
  • Optional cuff calibration learns a personal offset to better match your validated monitor

DESIGNED FOR CLARITY

  • Live camera preview so you always know which lens to cover
  • Colorful, modern interface with glowing cards and clear results
  • History charts and saved readings for up to one year (stored on your device as JSON)
  • Globe language picker: English, Portuguese (Brazil), Spanish, French, German, Hindi, Simplified Chinese, Telugu, Ukrainian, Russian, Italian, Arabic, and Norwegian

IMPORTANT — WELLNESS ONLY
Pressure4U is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease. Camera-based blood pressure and oxygen estimates are approximations for personal wellness. Always consult a qualified clinician for health decisions, and use a clinically validated cuff or pulse oximeter when medical accuracy is required.

Privacy-minded: measurements stay on your iPhone. Camera access is used only for fingertip scanning.
