Verdict
The clearest difference is rating: Summit Racing at 4.8 against McMaster's 4.3. Summit Racing also leads on ratings volume (65K vs 220). McMaster's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Summit Racing holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Summit Racing has 65K ratings behind it against 220, so its average is the more settled of the two. Written reviews point the same way: 68% of McMaster's written reviews are positive against 76% of Summit Racing's.
McMaster ships an update every 5 weeks, Summit Racing every 2 months. The most recent releases landed on September 17, 2026 and September 30, 2026 respectively.
