EyeChart - Vision Screening 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

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 EyeChart - Vision Screening
The most accurate, advanced visual acuity screening app for iPhone and iPod Touch. Over 1,000,000 people have downloaded our mobile electronic eye charts for iOS.
This version is our best for iPhone, and it's now completely free.
Useful for:
- Triaging
- House visits
- Patients who have memorized the office chart
Features:
- Randomizable Snellen Chart
- Randomizable Tumbling E Chart
- Randomizable Sloan Letters Chart
- Randomizable Landolt C Chart
- Randomizable Near Vision Chart (w/subscription)
- Line Isolation (w/subscription)
- Amsler Grid (w/subscription)
- Single optotype charts (w/subscription)
Description:
EyeChart is a pocket vision screener: randomized Snellen, Sloan, Tumbling E, and Landolt C charts to offer a rough but useful screen of visual acuity. Simply press a button to randomize the entire eye chart, or touch an individual line of the chart to randomize that line. Swipe right for the chart selector.
Eye care professionals around the world use Snellen Eye Charts to measure visual acuity. However, patients often memorize the classic Snellen chart, leading to less accurate vision measurements. Enter EyeChart! Though this unique, pocket-sized randomizable eye chart should not be used as a primary visual acuity measuring tool, it can provide a handy rough vision screen when a chart is not available, or it can be used to complement static, wall-based Snellen charts.
Subscription:
In addition to our free features, EyeChart offers a subscription to exclusive paid features, including the Randomizable Near Vision Chart, Line Isolation, Amsler Grid, and Single Optotype Charts! The subscription costs $0.99 per month of access, and is available through an auto-renewing subscription which will renew each month for your convenience until you choose to turn it off. Please let us know if you have any questions about your subscription at [email protected].
