Verdict
Path Tracer and Razer Cortex Mobile both sit at 4.4 stars, but that hides the real split: 79% of Path Tracer's written reviews are positive against 35% of Razer Cortex Mobile's. Path Tracer also leads on iOS requirement (11.0 vs 17). Razer Cortex Mobile's advantage is update cadence (every 2 months vs every 13 months) and ratings volume (3.5K vs 28). On price, rating, ads and in-app purchases there is nothing between them.

Razer Cortex Mobile holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Razer Cortex Mobile has 3.5K ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 79% of Path Tracer's written reviews are positive against 35% of Razer Cortex Mobile's, so the app with the better star average is not the one people write more warmly about.
Path Tracer ships an update every 13 months, Razer Cortex Mobile every 2 months. The most recent releases landed on October 5, 2026 and October 14, 2026 respectively.
