Verdict
The clearest difference is in-app purchases: NATS App at none against OhmQuest's 1. NATS App also leads on iOS requirement (9 vs 15.0). OhmQuest's advantage is update cadence (every 10 days vs every 3 months). On price, ads, monetization model and device support there is nothing between them.
