# Sudoku vs PermuLogic

The clearest difference is review sentiment: PermuLogic at 100% against Sudoku's 50%. PermuLogic also leads on in-app purchases (none vs 3) and ads (none vs shown). Sudoku's advantage is ratings volume (659 vs 2) and iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Sudoku sells 3 in-app purchases, starting at $0.99 per month. PermuLogic asks for nothing beyond the download.

PermuLogic holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sudoku has 659 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of Sudoku's written reviews are positive against 100% of PermuLogic's.
