ReceptionRating · Positive reviews · Number of ratings

Philips Air+ holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Philips Air+ has 1.4K ratings behind it against 207, so its average is the more settled of the two. Written reviews complicate that: 56% of UNDOK's written reviews are positive against 48% of Philips Air+'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

UNDOK ships an update every 6 weeks, Philips Air+ every 2 months. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
