# ACE Library vs Inkling

The clearest difference is rating: Inkling at 4.5 against ACE Library's 2.6. Inkling also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (2.4K vs 36). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Inkling holds the better App Store score, 4.5 against 2.6. That said, the two scores are not equally well evidenced: Inkling has 2.4K ratings behind it against 36, so its average is the more settled of the two.
