ReceptionRating · Positive reviews · Number of ratings

Philips Air+ holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Philips Air+ has 1.4K ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 52% of Klarstein'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

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