# Iron Prototype vs Cobalt

The clearest difference is rating: Cobalt at 5.0 against Iron Prototype's 3.9. Cobalt also leads on update cadence (every 10 days vs monthly). Iron Prototype's advantage is ratings volume (21 vs 3) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Cobalt holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Iron Prototype has 21 ratings behind it against 3, so its average is the more settled of the two.

Iron Prototype ships an update monthly, Cobalt every 10 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
