Verdict
The clearest difference is rating: DJI Fly at 3.7 against J's 2.9. DJI Fly also leads on ratings volume (4.9K vs 10) and review sentiment (38% vs 20%). J's advantage is monetization model (free vs ad-supported) and iOS requirement (7.0 vs 13.0). On price, update cadence, ads and in-app purchases there is nothing between them.
