# Kids Planet Discovery! vs Math Vs Undead

The clearest difference is rating: Math Vs Undead at 4.3 against Kids Planet Discovery!'s 3.0. Math Vs Undead also leads on ratings volume (148 vs 26). Kids Planet Discovery!'s advantage is ads (none vs shown) and update cadence (every 2 months vs every 6 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Kids Planet Discovery! sells 9 one-off in-app purchases and Math Vs Undead sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Math Vs Undead holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Math Vs Undead has 148 ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 59% of Kids Planet Discovery!'s written reviews are positive against 48% of Math Vs Undead's, so the app with the better star average is not the one people write more warmly about.

Kids Planet Discovery! ships an update every 2 months, Math Vs Undead every 6 months. The most recent releases landed on November 10, 2026 and November 6, 2026 respectively.
