# Insomnia vs Rhythm：ヘルスデータ書き出し

Insomnia and Rhythm：ヘルスデータ書き出し are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Insomnia sells 3 in-app purchases, starting at $4.99 per month and Rhythm：ヘルスデータ書き出し sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
