# Denksport BE vs Puzzle IO

The clearest difference is ads: Denksport BE at none against Puzzle IO's shown. Denksport BE also leads on rating (5.0 vs 4.6). Puzzle IO's advantage is ratings volume (362 vs 1) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Denksport BE sells 10 one-off in-app purchases and Puzzle IO sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Denksport BE holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Puzzle IO has 362 ratings behind it against 1, so its average is the more settled of the two.

Denksport BE ships an update every 2 months, Puzzle IO every 3 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
