Verdict
The clearest difference is rating: Part66 at 4.5 against VRflow A320's 4.0. Part66 also leads on ratings volume (10 vs 2) and iOS requirement (10.3 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Part66 sells 11 one-off in-app purchases and VRflow A320 sells 1 in-app purchase, starting at $22.49 per month. Whichever you choose, the download price is not the number that matters.
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.
Both ship on a similar rhythm, roughly every 2 months. Both last shipped on September 30, 2026.
