# Hashi vs Puzzle IO

The clearest difference is ads: Hashi at none against Puzzle IO's shown. Hashi also leads on review sentiment (94% vs 74%) and rating (4.9 vs 4.6). Puzzle IO's advantage is update cadence (every 3 weeks vs every 4 months) and iOS requirement (13.0 vs 15.6). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Hashi 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.

Hashi holds the better App Store score, 4.9 against 4.6. Both are backed by a comparable volume of ratings — 1K and 362 respectively. Written reviews point the same way: 94% of Hashi's written reviews are positive against 74% of Puzzle IO's.

Hashi ships an update every 4 months, Puzzle IO every 3 weeks. The most recent releases landed on November 10, 2026 and November 2, 2026 respectively.
