# HRV4Training vs Elonga

The clearest difference is price: Elonga at Free against HRV4Training's $9.99. Elonga also leads on rating (4.8 vs 3.6) and update cadence (every 2 weeks vs every 6 weeks). HRV4Training's advantage is review sentiment (61% vs 44%) and ratings volume (288 vs 20). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

Elonga is free to download; HRV4Training costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Elonga holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: HRV4Training has 288 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 61% of HRV4Training's written reviews are positive against 44% of Elonga's, so the app with the better star average is not the one people write more warmly about.

HRV4Training ships an update every 6 weeks, Elonga every 2 weeks. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
