# SelfLoops HRV vs Optimal HRV

The clearest difference is review sentiment: SelfLoops HRV at 75% against Optimal HRV's 17%. SelfLoops HRV also leads on rating (5.0 vs 3.0). Optimal HRV's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (24 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SelfLoops HRV sells 1 one-off in-app purchase and Optimal HRV sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
