# OutDoors GB vs GPS OS Grid Reference

The clearest difference is price: GPS OS Grid Reference at Free against OutDoors GB's $1.99. GPS OS Grid Reference also leads on review sentiment (90% vs 55%). OutDoors GB's advantage is rating (5.0 vs 4.4) and update cadence (fortnightly vs every 3 months). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.

GPS OS Grid Reference is free to download; OutDoors GB costs $1.99 up front. OutDoors GB sells 10 in-app purchases, starting at $12.99 per year and GPS OS Grid Reference sells 2 in-app purchases, starting at $5.99 per year. Whichever you choose, the download price is not the number that matters.

OutDoors GB holds the better App Store score, 5.0 against 4.4. Both are backed by a comparable volume of ratings — 14 and 17 respectively. Written reviews complicate that: 55% of OutDoors GB's written reviews are positive against 90% of GPS OS Grid Reference's, so the app with the better star average is not the one people write more warmly about.

OutDoors GB ships an update fortnightly, GPS OS Grid Reference every 3 months. Both last shipped on October 29, 2026.
