# TUO Life vs HRV4Biofeedback

The clearest difference is price: TUO Life at Free against HRV4Biofeedback's $9.99. TUO Life also leads on rating (3.9 vs 3.4) and ratings volume (161 vs 29). HRV4Biofeedback's advantage is review sentiment (53% vs 35%) and chart position (#199 vs unranked). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

TUO Life is free to download; HRV4Biofeedback costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

TUO Life holds the better App Store score, 3.9 against 3.4. That said, the two scores are not equally well evidenced: TUO Life has 161 ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 35% of TUO Life's written reviews are positive against 53% of HRV4Biofeedback's, so the app with the better star average is not the one people write more warmly about.

TUO Life ships an update every 3 months, HRV4Biofeedback every 2 months. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
