# Cairn vs Gyroscope

The clearest difference is ads: Cairn at none against Gyroscope's shown. Cairn also leads on review sentiment (84% vs 65%) and ratings volume (533 vs 50). Gyroscope's advantage is update cadence (every 9 days vs every 3 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cairn sells 2 in-app purchases, starting at $4.99 per month and Gyroscope sells 8 in-app purchases, starting at $9.00 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Cairn against 4.8 for Gyroscope. That said, the two scores are not equally well evidenced: Cairn has 533 ratings behind it against 50, so its average is the more settled of the two. Written reviews are what separate them: 84% of Cairn's written reviews are positive against 65% of Gyroscope's.

Cairn ships an update every 3 months, Gyroscope every 9 days. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
