Internet connection is required. Zoom in to street level, app will show you 10 digit locator. Note: Usually Grid Locator is 6 digit as defined in ARRL document. This 10 digit is expansion of 6 digit as 7th and 8th are divided by 10 ("0" through "9") then 9th and 10th are divided by 24 ("a" through "x"). This logic is based on article on Wikipedia.

Verdict
The clearest difference is rating: Tinker DIY at 4.7 against Grid Locator Finder's 2.0. Tinker DIY also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (2K vs 2). Grid Locator Finder's advantage is review sentiment (67% vs 45%) and monetization model (free vs ad-supported). On price, ads, 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.
Tinker DIY holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: Tinker DIY has 2K 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 45% of Tinker DIY's, so the app with the better star average is not the one people write more warmly about.
Grid Locator Finder ships an update every 4 months, Tinker DIY every 3 weeks. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
