# Grid Locator Finder vs Smart911

The clearest difference is rating: Smart911 at 4.7 against Grid Locator Finder's 2.0. Smart911 also leads on ratings volume (6.8K vs 2). Grid Locator Finder's advantage is review sentiment (67% vs 37%) and iOS requirement (10.0 vs 16). On price, update cadence, 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.

Smart911 holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: Smart911 has 6.8K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Grid Locator Finder's written reviews are positive against 37% of Smart911's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on October 23, 2026 and October 27, 2026 respectively.
