# Osmosis vs PathoPlay

The clearest difference is update cadence: PathoPlay at every 5 days against Osmosis's monthly. Osmosis's advantage is ratings volume (877 vs 4) and chart position (#165 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Osmosis sells 10 in-app purchases, starting at $29.00 per month and PathoPlay sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Osmosis against 5.0 for PathoPlay. That said, the two scores are not equally well evidenced: Osmosis has 877 ratings behind it against 4, so its average is the more settled of the two.

Osmosis ships an update monthly, PathoPlay every 5 days. The most recent releases landed on November 7, 2026 and November 8, 2026 respectively.
