# Quantum X Planet Defense vs Soul Quest

The clearest difference is rating: Soul Quest at 4.3 against Quantum X Planet Defense's 3.0. Soul Quest also leads on update cadence (weekly vs every 2 months) and ratings volume (1.4K vs 10). Quantum X Planet Defense's advantage is in-app purchases (none vs 22) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Soul Quest sells 22 one-off in-app purchases. Quantum X Planet Defense asks for nothing beyond the download.

Soul Quest holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Soul Quest has 1.4K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 36% of Quantum X Planet Defense's written reviews are positive against 6% of Soul Quest's, so the app with the better star average is not the one people write more warmly about.

Quantum X Planet Defense ships an update every 2 months, Soul Quest weekly. Both last shipped on October 24, 2026.
