# Centile vs HeightMax

The clearest difference is rating: HeightMax at 5.0 against Centile's 4.0. HeightMax also leads on monetization model (free with in-app purchases vs subscription). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Centile sells 3 in-app purchases, starting at $6.99 per 7 days and HeightMax sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
