# ThinkCar pro vs DFirstCoder

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.

Both are free to download. DFirstCoder sells 8 in-app purchases, starting at $108.99 per year. ThinkCar pro asks for nothing beyond the download.

DFirstCoder holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: ThinkCar pro has 323 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 62% of ThinkCar pro's written reviews are positive against 67% of DFirstCoder's.

ThinkCar pro ships an update every 5 months, DFirstCoder every 3 weeks. Both last shipped on October 7, 2026.
