# HeightGPT vs Centile

The clearest difference is rating: HeightGPT at 4.4 against Centile's 4.0. HeightGPT also leads on ratings volume (16 vs 1) and device support (3 vs 1). Centile's advantage is update cadence (every 2 days vs weekly). On price, ads and in-app purchases there is nothing between them.

Both are free to download. HeightGPT sells 2 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.

HeightGPT holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: HeightGPT has 16 ratings behind it against 1, so its average is the more settled of the two.

HeightGPT ships an update weekly, Centile every 2 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
