# HeartRay vs ATMÓS

The clearest difference is update cadence: HeartRay at every 2 days against ATMÓS's fortnightly. ATMÓS's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. HeartRay sells 2 in-app purchases, starting at $0.99 per month and ATMÓS sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

HeartRay ships an update every 2 days, ATMÓS fortnightly. The most recent releases landed on October 14, 2026 and October 10, 2026 respectively.
