Verdict
The clearest difference is price: TrailRig at Free against eMaxMobileApp's $0.99. TrailRig also leads on update cadence (every 4 days vs every 3 weeks). eMaxMobileApp's advantage is in-app purchases (none vs 1) and iOS requirement (15.6 vs 17.0). On ads and device support there is nothing between them.
