ReceptionRating · Positive reviews · Number of ratings

BluVac holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: dDrives has 32 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of dDrives'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.

UpkeepUpdate frequency

dDrives ships an update monthly, BluVac every 2 months. The most recent releases landed on October 24, 2026 and October 12, 2026 respectively.
