# GS vs mi3

GS and mi3 both sit at 4.5 stars, but that hides the real split: 100% of mi3's written reviews are positive against 36% of GS's. mi3 also leads on iOS requirement (13.0 vs 15.0). GS's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (341 vs 16). On price, rating, ads 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.

On the App Store both sit at effectively the same score — 4.5 for GS against 4.4 for mi3. That said, the two scores are not equally well evidenced: GS has 341 ratings behind it against 16, so its average is the more settled of the two. Written reviews are what separate them: 36% of GS's written reviews are positive against 100% of mi3's.

GS ships an update fortnightly, mi3 every 4 months. The most recent releases landed on October 29, 2026 and November 3, 2026 respectively.
