Verdict
The clearest difference is review sentiment: Zero Sum at 100% against Ride Master's 54%. Zero Sum also leads on update cadence (every 3 days vs every 6 weeks). Ride Master's advantage is chart position (#55 vs unranked) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.
