Verdict
The clearest difference is rating: JINAIR at 4.2 against Trinity Airways's 1.0. JINAIR also leads on monetization model (free vs free with in-app purchases) and ratings volume (211 vs 1). Trinity Airways's advantage is update cadence (fortnightly vs every 5 weeks). On price, ads, in-app purchases and device support there is nothing between them.
