# Medi TD vs Underdark

The clearest difference is in-app purchases: Medi TD at none against Underdark's 10. Medi TD also leads on rating (5.0 vs 4.8) and iOS requirement (10.0 vs 15.0). Underdark's advantage is review sentiment (72% vs 40%) and ratings volume (4.1K vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Underdark sells 10 one-off in-app purchases. Medi TD asks for nothing beyond the download.

Medi TD holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Underdark has 4.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 40% of Medi TD's written reviews are positive against 72% of Underdark's, so the app with the better star average is not the one people write more warmly about.

Medi TD ships an update every 10 days, Underdark every 4 days. The most recent releases landed on November 3, 2026 and November 12, 2026 respectively.
