# Binary Sudoku+ vs Proofline

The clearest difference is ratings volume: Binary Sudoku+ at 190 against Proofline's 1. Binary Sudoku+ also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). Proofline's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Binary Sudoku+ sells 8 in-app purchases, starting at $4.99 per month and Proofline sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Proofline holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Binary Sudoku+ has 190 ratings behind it against 1, so its average is the more settled of the two.
