Verdict

The call

The clearest difference is in-app purchases: Social Rhythms at none against Lune's 3. Social Rhythms also leads on rating (4.1 vs 3.8). Lune's advantage is review sentiment (25% vs 0%) and ratings volume (200 vs 7). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Social Rhythms holds the better App Store score, 4.1 against 3.8. That said, the two scores are not equally well evidenced: Lune has 200 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 0% of Social Rhythms's written reviews are positive against 25% of Lune's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Social Rhythms ships an update every 2 months, Lune monthly. Both last shipped on November 4, 2026.
