# Tallify vs Centile

The clearest difference is rating: Tallify at 4.6 against Centile's 4.0. Tallify also leads on ratings volume (11 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. Tallify sells 2 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.

Tallify holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Tallify has 11 ratings behind it against 1, so its average is the more settled of the two.

Tallify ships an update every 3 weeks, Centile every 2 days. Both last shipped on October 31, 2026.
