# StairClimbs vs Opthy

The clearest difference is rating: Opthy at 4.5 against StairClimbs's 2.9. Opthy also leads on ratings volume (2.9K vs 10) and update cadence (monthly vs every 5 months). StairClimbs's advantage is iOS requirement (8.0 vs 14.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Opthy holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: Opthy has 2.9K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 20% of StairClimbs's written reviews are positive against 13% of Opthy's, so the app with the better star average is not the one people write more warmly about.

StairClimbs ships an update every 5 months, Opthy monthly. The most recent releases landed on October 7, 2026 and October 19, 2026 respectively.
