Verdict

The call

The clearest difference is ads: GPS OS Grid Reference at none against onX Hunt's shown. GPS OS Grid Reference also leads on review sentiment (90% vs 62%). onX Hunt's advantage is rating (4.9 vs 4.4) and update cadence (every 2 weeks vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. onX Hunt sells 10 in-app purchases, starting at $14.99 per month 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.

ReceptionRating · Positive reviews · Number of ratings

onX Hunt holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: onX Hunt has 275K ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 62% of onX Hunt'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.

UpkeepUpdate frequency

onX Hunt ships an update every 2 weeks, GPS OS Grid Reference every 3 months. The most recent releases landed on October 28, 2026 and October 26, 2026 respectively.
