Need a Snellen eye chart for a quick at-home vision check or a classroom? ChartEye makes a true-size Snellen-style eye chart for your viewing distance, on screen and as a printable PDF. Set the viewing distance from 5 to 20 feet. Each letter's height follows the Snellen standard — a 20/20 letter subtends 5 arc minutes at that distance — so the rows are the right size when you stand back at the chosen distance. • EIGHT SNELLEN ROWS — from 20/200 down to 20/20, each labeled with its acuity value, at every distance from 5 to 20 ft. • TRUE-SIZE PRINTABLE PDF — letters sized by their actual printed height; when the rows need more room, the chart continues on a second Letter page instead of leaving any row out. A 100 mm scale bar lets you confirm the printer didn't shrink the page. • TRUE-SIZE ON SCREEN — after a quick card calibration, the phone shows one row at a time at its real size; step between larger and smaller rows. • TUMBLING E — a chart for children or anyone who doesn't read Latin letters, with each E facing a random direction; shuffle for a fresh set. • CARD CALIBRATION — hold a bank or debit card upright against the screen and match the outline, so the on-screen letters are true size on your device. ChartEye is a screening aid only. It is not a medical device, does not diagnose anything and is not a substitute for a professional eye exam. If you notice any change in your vision, see an optometrist or ophthalmologist. Everything is made on your device; no account needed. The on-screen chart is free, and your first 3 PDF charts are free. A one-time $4.99 unlock gives you unlimited PDFs. No subscription, no ads. Questions: overlapmarr@gmail.com

Verdict
The clearest difference is update cadence: ChartEye at every 2 weeks against Block Apps's every 5 weeks. ChartEye also leads on iOS requirement (16.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
