# Carbon vs AXIS HP

Both are free to download. Carbon sells 9 in-app purchases, starting at $11.99 per month. AXIS HP asks for nothing beyond the download.

AXIS HP holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Carbon has 8.2K ratings behind it against 4, so its average is the more settled of the two.
