# McMaster vs Summit Racing

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
