# Coherence vs SOUND HSA

The clearest difference is in-app purchases: SOUND HSA at none against Coherence's 6. SOUND HSA also leads on review sentiment (100% vs 85%). Coherence's advantage is rating (4.8 vs 4.4) and ratings volume (619 vs 7). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Coherence sells 6 in-app purchases, starting at $14.99 per month. SOUND HSA asks for nothing beyond the download.

Coherence holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Coherence has 619 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 85% of Coherence's written reviews are positive against 100% of SOUND HSA's, so the app with the better star average is not the one people write more warmly about.

Coherence ships an update every 4 days, SOUND HSA every 2 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
