# Sudoku Solver Realtime Camera vs Answer AI

The clearest difference is rating: Answer AI at 4.6 against Sudoku Solver Realtime Camera's 3.4. Answer AI also leads on update cadence (weekly vs monthly) and ratings volume (433 vs 43). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Sudoku Solver Realtime Camera sells 4 in-app purchases, starting at $1.99 per 7 days and Answer AI sells 5 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Answer AI holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: Answer AI has 433 ratings behind it against 43, so its average is the more settled of the two. Written reviews point the same way: 19% of Sudoku Solver Realtime Camera's written reviews are positive against 21% of Answer AI's.

Sudoku Solver Realtime Camera ships an update monthly, Answer AI weekly. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
