The short version
Both are sub-$100/year structured breathwork apps. Breathwrk is the science-grounded structured-library reference. SOMA is the rhythmic-music-paced ceremony-framing alternative.
When Breathwrk is the right pick
If you want the largest structured catalogue with evidence-grounded copy and broadest technique coverage — Breathwrk is the right shape at lower price.
When SOMA Breath is the right pick
If you want beat-paced rhythmic music breathwork with ceremony framing and access to a global certified-facilitator community — SOMA is the right shape.
