Verdict
The clearest difference is in-app purchases: Noraxon Biofeedback at none against GrafSets's 3. Noraxon Biofeedback also leads on iOS requirement (15.0 vs 17.0). GrafSets's advantage is update cadence (every 2 days vs every 3 months). On price, ads and device support there is nothing between them.
