# Taller App vs Centile

The clearest difference is rating: Taller App at 4.7 against Centile's 4.0. Taller App also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (515 vs 1). Centile's advantage is update cadence (every 2 days vs fortnightly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Taller App sells 8 in-app purchases, starting at $3.99 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.

Taller App holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Taller App has 515 ratings behind it against 1, so its average is the more settled of the two.

Taller App ships an update fortnightly, Centile every 2 days. The most recent releases landed on November 8, 2026 and November 10, 2026 respectively.
