ReceptionRating · Positive reviews · Number of ratings

Reflex holds the better App Store score, 3.5 against 1.0. That said, the two scores are not equally well evidenced: Reflex has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Reflex's written reviews are positive against 14% of EyeTracker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Reflex ships an update every 2 weeks, EyeTracker monthly. The most recent releases landed on September 10, 2026 and June 25, 2026 respectively.
