# Eye Chart HD vs Eye Pro

The clearest difference is rating: Eye Chart HD at 5.0 against Eye Pro's 1.0. Eye Chart HD also leads on ratings volume (5 vs 1). Eye Pro's advantage is ads (none vs shown) and update cadence (every 10 days vs every 6 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Eye Chart HD sells 2 in-app purchases, starting at $2.99 per month and Eye Pro sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Eye Chart HD holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: Eye Chart HD has 5 ratings behind it against 1, so its average is the more settled of the two.

Eye Chart HD ships an update every 6 months, Eye Pro every 10 days. The most recent releases landed on September 25, 2026 and September 13, 2026 respectively.
