ReceptionRating · Positive reviews · Number of ratings

Part66 holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Part66 has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 60% of Part66's written reviews are positive against 67% of VRflow A320's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on September 30, 2026.
