# Standly vs Centile

The clearest difference is rating: Standly at 4.6 against Centile's 4.0. Standly also leads on ratings volume (115 vs 1) and iOS requirement (15.1 vs 17.0). Centile's advantage is update cadence (every 2 days vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Standly sells 4 in-app purchases, starting at $4.99 per 7 days and Centile sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Standly holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Standly has 115 ratings behind it against 1, so its average is the more settled of the two.

Standly ships an update every 3 weeks, Centile every 2 days. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
