Verdict
The clearest difference is in-app purchases: ThinkCar pro at none against DFirstCoder's 8. ThinkCar pro also leads on ratings volume (323 vs 5) and iOS requirement (9.0 vs 13.0). DFirstCoder's advantage is update cadence (every 3 weeks vs every 5 months) and rating (4.8 vs 4.6). On price, review sentiment, ads and device support there is nothing between them.
