Verdict

The call

The clearest difference is rating: Owaves at 4.6 against Marshmallows's 3.8. Owaves also leads on ratings volume (1.8K vs 4) and device support (3 vs 1). Marshmallows's advantage is in-app purchases (none vs 6) and update cadence (every 4 days vs every 4 weeks). On price and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Owaves holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: Owaves has 1.8K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 70% of Owaves's written reviews are positive against 80% of Marshmallows's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Owaves ships an update every 4 weeks, Marshmallows every 4 days. The most recent releases landed on October 22, 2026 and October 21, 2026 respectively.
