# Carb Manager vs Studio 8

The clearest difference is in-app purchases: Studio 8 at none against Carb Manager's 10. Studio 8 also leads on iOS requirement (13.0.0 vs 15.6). Carb Manager's advantage is ratings volume (737K vs 1) and chart position (#130 vs unranked). On price, rating, ads and device support there is nothing between them.

Both are free to download. Carb Manager sells 8 in-app purchases, starting at $8.49 per month. Studio 8 asks for nothing beyond the download.

Studio 8 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Carb Manager has 737K ratings behind it against 1, so its average is the more settled of the two.
