# Immersion Mobile vs KHR

The clearest difference is rating: KHR at 5.0 against Immersion Mobile's 4.3. KHR also leads on update cadence (fortnightly vs monthly). Immersion Mobile's advantage is ratings volume (12 vs 2) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

KHR holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Immersion Mobile has 12 ratings behind it against 2, so its average is the more settled of the two.

Immersion Mobile ships an update monthly, KHR fortnightly. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
