Verdict

The call

The clearest difference is rating: cal at 4.5 against DJI Virtual Flight's 3.9. cal also leads on review sentiment (71% vs 34%) and update cadence (weekly vs every 2 months). DJI Virtual Flight's advantage is ads (none vs shown) and ratings volume (1.8K vs 17). On price, in-app purchases, device support and iOS requirement there is nothing between them.
