iElastance downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About iElastance
iElastance estimates left ventricular end-systolic elastance (Ees), effective arterial elastance (Ea) and their ratio, ventricular–arterial coupling (VAC), from six values you already have at the bedside: cuff pressures, a standard echocardiogram and two systolic time intervals. No catheter, no extra equipment.
FREE
• Single-beat calculator (Chen et al., J Am Coll Cardiol 2001): systolic and diastolic pressure, ejection fraction, stroke volume, pre-ejection and total ejection time.
• Results update as you type, with checks on impossible values.
• "How to measure" guide with diagrams of the method of disks and of systolic times on the LVOT pulsed Doppler.
IELASTANCE PREMIUM
• Pressure–volume diagram: ESPVR and Ea lines, stroke volume, ESP, EDV, ESV and V0.
• Cases: keep your 10 most recent cases, each with as many measurements as you need (baseline, after fluids, after a vasopressor or inotrope…).
• Trends of VAC, Ea and Ees over time.
• PDF report with results, diagrams, measurement table, trends, method and reference, ready to print or share.
• Archive export and import to move your cases to another device.
