# Puzzle IO vs Binary Logic

The clearest difference is ads: Binary Logic at none against Puzzle IO's shown. Binary Logic also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 75%). Puzzle IO's advantage is ratings volume (348 vs 2) and iOS requirement (13.0 vs 18.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Puzzle IO sells 1 one-off in-app purchase and Binary Logic sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Binary Logic holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Puzzle IO has 348 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 75% of Puzzle IO's written reviews are positive against 100% of Binary Logic's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 18, 2026 and September 20, 2026 respectively.
