Verdict

The call

Reaction Speed Reflex Trainer and Fast Reflex both sit at 4.6 stars, but that hides the real split: 100% of Fast Reflex's written reviews are positive against 53% of Reaction Speed Reflex Trainer's. Fast Reflex also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 3 months). Reaction Speed Reflex Trainer's advantage is price (Free vs $0.99) and ratings volume (1.5K vs 47). On rating, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Reaction Speed Reflex Trainer holds the better App Store score, 4.6 against 4.5. That said, the two scores are not equally well evidenced: Reaction Speed Reflex Trainer has 1.5K ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 53% of Reaction Speed Reflex Trainer's written reviews are positive against 100% of Fast Reflex's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Reaction Speed Reflex Trainer ships an update every 3 months, Fast Reflex every 2 weeks. The most recent releases landed on November 8, 2026 and November 2, 2026 respectively.
