# Petri vs MeMaze

The clearest difference is ads: MeMaze at none against Petri's shown. Petri's advantage is ratings volume (34 vs 1) and device support (4 vs 2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Petri sells 1 one-off in-app purchase and MeMaze sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Petri against 5.0 for MeMaze. That said, the two scores are not equally well evidenced: Petri has 34 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Petri ships an update weekly, MeMaze fortnightly. The most recent releases landed on October 29, 2026 and September 13, 2026 respectively.
