ReceptionRating · Positive reviews · Number of ratings

NERD Synth A2x + AUv3 holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: NERD Synth A2x + AUv3 has 1.4K ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 90% of Refraktions's written reviews are positive against 89% of NERD Synth A2x + AUv3's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Refraktions ships an update every 2 months, NERD Synth A2x + AUv3 fortnightly. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
