Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Lune sells 3 in-app purchases, starting at $39.99 per year. Social Rhythms asks for nothing beyond the download.
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.
Social Rhythms ships an update every 2 months, Lune monthly. Both last shipped on November 4, 2026.
