# Osmosis vs Combat Medic

The clearest difference is update cadence: Combat Medic at every 4 days against Osmosis's monthly. Combat Medic also leads on monetization model (free vs free with in-app purchases). Osmosis's advantage is ratings volume (3.9K vs 2) and chart position (#113 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 $16.99 per month and Combat Medic sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Combat Medic holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Osmosis has 3.9K ratings behind it against 2, so its average is the more settled of the two.

Osmosis ships an update monthly, Combat Medic every 4 days. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
