The clearest difference is review sentiment: Sym Breathing at 94% against BioCoherence's 50%. Sym Breathing also leads on rating (4.9 vs 4.5) and ratings volume (35 vs 6). BioCoherence's advantage is update cadence (every 9 days vs every 3 weeks) and device support (4 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. BioCoherence sells 11 in-app purchases, starting at $21.99 per month and Sym Breathing sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
