Unverified model estimate. Neither Apple nor the developer has published this number, and the real figure can be several times higher or lower. Low confidence: the real figure can be a band higher or lower.
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.
A trusted reference for ultrasound-guided regional anesthesia, used by anesthesiologists and pain specialists worldwide.
The app supports clinical preparation and learning across a wide range of regional anesthesia techniques. Covering nerve block procedures from head and neck to upper and lower extremities, thoracic, and abdominal wall blocks, it brings structured guidance and clear anatomy into one focused reference.
Commonly performed techniques such as TAP (Transversus Abdominis Plane) block, ESP (Erector Spinae Plane) block, Interscalene Brachial Plexus Block, and Popliteal Sciatic Nerve Block are presented alongside many other approaches, each with ultrasound-focused visuals, functional anatomy, and step-by-step preparation.
Designed for everyday use, the app combines sonoanatomy, patient positioning, and block-specific considerations to support confident decision-making before and during clinical practice.
Developed by NYSORA, a global educational organization dedicated to advancing regional anesthesia through structured, practice-focused education.
