ReceptionRating · Positive reviews · Number of ratings

Chill Drills holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Breathe2Relax has 317 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 78% of Breathe2Relax's written reviews are positive against 67% of Chill Drills's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Breathe2Relax ships an update every 24 months, Chill Drills every 4 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
