# Bunpo vs Grindstone

The clearest difference is in-app purchases: Grindstone at none against Bunpo's 10. Bunpo's advantage is ratings volume (18K vs 1) and iOS requirement (16.0 vs 18.6). On price, rating, ads and device support there is nothing between them.

Both are free to download. Bunpo sells 8 in-app purchases, starting at $9.99 per month. Grindstone asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Bunpo against 5.0 for Grindstone. That said, the two scores are not equally well evidenced: Bunpo has 18K ratings behind it against 1, so its average is the more settled of the two.
