AcuityMaster vs KyberVision Visual Acuity
Two Mac-capable acuity systems that both publish their pricing — a browser subscription against a Mac App Store purchase. Here is the honest side-by-side.
Quick verdict: AcuityMaster Cloud runs in the browser on Mac, Windows and iPad with a broad clinical test set — acuity plus color vision, Worth 4-Dot, fixation disparity and refraction-support targets — from $249 a year for a first seat. KyberVision’s Visual Acuity is macOS-native desktop software focused on logMAR acuity testing, listed at $99.99 one-time on the Mac App Store. For a single Mac and acuity-only needs, KyberVision is the budget pick; for mixed hardware, iPad lanes, or the wider test battery, AcuityMaster fits better.

The bottom line
KyberVision’s Visual Acuity is a credible, inexpensive, macOS-native acuity tester with a properly designed logMAR chart and a free iOS remote — and at $99.99 one-time it is the cheapest serious option a Mac-only practice will find. The differences that decide it are scope and posture: AcuityMaster covers the wider clinical battery (color vision, binocular tests, refraction-support targets, crowding bars for amblyopia work), runs on whatever hardware each lane happens to have, and stores no patient data at all — whereas KyberVision’s page describes patient history and prescription management, meaning patient records live on that Mac. Decide based on how many of those differences your practice actually uses.
Where each system fits
Choose KyberVision for a single Mac on a budget
One exam lane, one Mac, acuity testing only: a $99.99 one-time App Store purchase is hard to argue with, and the free iPhone/iPad remote covers control.
Choose AcuityMaster for the full test battery
Color vision screening, Worth 4-Dot, fixation disparity, duochrome, reduced-contrast levels and crowding bars ship alongside the acuity charts — one system for the whole lane, not just the letters.
Mind the patient-data difference
AcuityMaster stores no patient information whatsoever — nothing to secure, nothing to breach. KyberVision’s history and prescription features mean records live on the exam-lane Mac; factor that machine into your privacy and backup posture if you go that way.
Common questions
Is AcuityMaster a good alternative to KyberVision Visual Acuity?
Both run on a Mac and both publish pricing. AcuityMaster Cloud runs in the browser on Mac, Windows and iPad with a broader clinical test set — color vision, Worth 4-Dot, fixation disparity, astigmatic dial and duochrome alongside the acuity charts — on an annual subscription. KyberVision’s Visual Acuity is a one-time Mac App Store purchase focused on logMAR acuity testing. A single-Mac practice that wants a one-time purchase may prefer KyberVision; a mixed-hardware practice or one wanting the wider test set will find AcuityMaster the better fit.
How does AcuityMaster pricing compare to KyberVision?
AcuityMaster Cloud is an annual subscription: $249 per year for the first seat, with lower graduated band rates above (10 seats total $1,280 per year). KyberVision’s Visual Acuity was listed at $99.99 as a one-time purchase on the Mac App Store when checked in August 2026. Over multiple years a one-time purchase can cost less for a single lane; the subscription includes automatic updates, more test types, and runs on Windows and iPad as well.
Does either product store patient data?
KyberVision’s product page describes patient history tracking and prescription management, so it stores patient records on the Mac it runs on. AcuityMaster deliberately stores no patient data at all — no names, no dates of birth, no results — which is a difference in kind: one is a testing tool with a patient database, the other is a display and testing system with none.
