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.

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.
What users say about EchoSource
From the 10 most recent App Store reviews in the US.
Users appreciate the comprehensive educational content and detailed illustrations for echocardiography basics. However, significant technical issues with video playback and conflicting reports regarding data accuracy are major detractors.
Mixed but leaning positive (60% of recent reviews give 4–5 stars). People like it for being useful. Recent reviews are more negative than earlier ones.
What people like
- Useful: “Nice content; but must have font size feature- tiny font is very difficult to read”
