# Biovibe vs Hz

The clearest difference is review sentiment: Hz at 100% against Biovibe's 67%. Hz also leads on update cadence (fortnightly vs every 6 weeks). Biovibe's advantage is iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Biovibe sells 2 in-app purchases, starting at $14.99 per month and Hz sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Biovibe ships an update every 6 weeks, Hz fortnightly. Both last shipped on November 4, 2026.
