Verdict
The clearest difference is price: BioSign HRV at Free against HRV4Biofeedback's $9.99. BioSign HRV also leads on rating (5.0 vs 3.4) and update cadence (fortnightly vs every 2 months). HRV4Biofeedback's advantage is ratings volume (29 vs 1) and chart position (#91 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
