# iManifold vs BluVac

The clearest difference is rating: BluVac at 5.0 against iManifold's 3.1. BluVac also leads on in-app purchases (none vs 10). iManifold's advantage is ratings volume (38 vs 2) and review sentiment (50% vs 36%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. iManifold sells 10 one-off in-app purchases. BluVac asks for nothing beyond the download.

BluVac holds the better App Store score, 5.0 against 3.1. That said, the two scores are not equally well evidenced: iManifold has 38 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of iManifold's written reviews are positive against 36% of BluVac's, so the app with the better star average is not the one people write more warmly about.

iManifold ships an update every 3 weeks, BluVac every 2 months. Both last shipped on October 12, 2026.
