# Mars vs Discover Mars

The clearest difference is in-app purchases: Discover Mars at none against Mars's 1. Discover Mars also leads on ads (none vs shown) and update cadence (monthly vs every 6 months). On price, rating and device support there is nothing between them.

Both are free to download. Mars sells 1 one-off in-app purchase. Discover Mars asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Mars against 5.0 for Discover Mars. That said, the two scores are not equally well evidenced: Discover Mars has 12 ratings behind it against 2, so its average is the more settled of the two.

Mars ships an update every 6 months, Discover Mars monthly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
