Verdict
The clearest difference is monetization model: Viome at free with in-app purchases against Function Health's subscription. Viome also leads on device support (3 vs 1). Function Health's advantage is update cadence (weekly vs every 6 weeks) and rating (4.9 vs 4.6). On price, ads, in-app purchases and iOS requirement there is nothing between them.
