# myGMC vs Halo Collar

The clearest difference is rating: myGMC at 4.8 against Halo Collar's 4.1. myGMC also leads on monetization model (ad-supported vs paid) and ratings volume (430K vs 9.2K). Halo Collar's advantage is ads (none vs shown) and review sentiment (70% vs 36%). On price, update cadence, in-app purchases and device support there is nothing between them.

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

myGMC holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: myGMC has 430K ratings behind it against 9.2K, so its average is the more settled of the two. Written reviews complicate that: 36% of myGMC's written reviews are positive against 70% of Halo Collar's, so the app with the better star average is not the one people write more warmly about.

myGMC ships an update fortnightly, Halo Collar every 3 weeks. Both last shipped on September 24, 2026.
