# Sym Breathing vs Klock

The clearest difference is ratings volume: Sym Breathing at 35 against Klock's 3. Klock's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Sym Breathing sells 3 in-app purchases, starting at $0.99 per month and Klock sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Sym Breathing against 5.0 for Klock. That said, the two scores are not equally well evidenced: Sym Breathing has 35 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 94% of Sym Breathing's written reviews are positive against 100% of Klock's.

Sym Breathing ships an update every 3 weeks, Klock every 10 days. The most recent releases landed on October 6, 2026 and September 24, 2026 respectively.
