# PhaseRings vs Scaler 3

The clearest difference is price: PhaseRings at Free against Scaler 3's $12.99. PhaseRings also leads on review sentiment (80% vs 57%) and device support (3 vs 1). Scaler 3's advantage is update cadence (fortnightly vs every 5 months) and rating (4.7 vs 4.5). On ads, in-app purchases and iOS requirement there is nothing between them.

PhaseRings is free to download; Scaler 3 costs $12.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Scaler 3 holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Scaler 3 has 165 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 80% of PhaseRings's written reviews are positive against 57% of Scaler 3's, so the app with the better star average is not the one people write more warmly about.

PhaseRings ships an update every 5 months, Scaler 3 fortnightly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
