Verdict
myGMC and Corn Score both sit at 4.8 stars, but that hides the real split: 100% of Corn Score's written reviews are positive against 37% of myGMC's. Corn Score also leads on ads (none vs shown). myGMC's advantage is price (Free vs $0.99) and ratings volume (442K vs 34). On rating, in-app purchases, chart position and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
myGMC is free to download; Corn Score costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
myGMC holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: myGMC has 442K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 37% of myGMC's written reviews are positive against 100% of Corn Score's, so the app with the better star average is not the one people write more warmly about.
myGMC ships an update fortnightly, Corn Score monthly. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
