# GPS51 vs IOPGPS

The clearest difference is rating: IOPGPS at 4.2 against GPS51's 3.7. IOPGPS also leads on ratings volume (9 vs 3). GPS51's advantage is update cadence (every 4 days vs every 3 weeks) and review sentiment (54% vs 40%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

IOPGPS holds the better App Store score, 4.2 against 3.7. Both are backed by a comparable volume of ratings — 3 and 9 respectively. Written reviews complicate that: 54% of GPS51's written reviews are positive against 40% of IOPGPS's, so the app with the better star average is not the one people write more warmly about.
