# HRV4Training vs Training Today

The clearest difference is price: Training Today at Free against HRV4Training's $9.99. Training Today also leads on rating (4.6 vs 3.6) and ratings volume (2.6K vs 288). HRV4Training's advantage is in-app purchases (none vs 4) and chart position (#20 vs unranked). On update cadence, ads, device support and iOS requirement there is nothing between them.

Training Today is free to download; HRV4Training costs $9.99 up front. Training Today sells 4 in-app purchases, starting at $2.95 per month. HRV4Training asks for nothing beyond the download.

Training Today holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: Training Today has 2.6K ratings behind it against 288, so its average is the more settled of the two. Written reviews complicate that: 61% of HRV4Training's written reviews are positive against 53% of Training Today's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 6 weeks. Both last shipped on October 13, 2026.
