# GPS Speedometer vs EMFMeter

The clearest difference is rating: EMFMeter at 4.7 against GPS Speedometer's 4.0. GPS Speedometer's advantage is ratings volume (4.2K vs 98) and device support (4 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. GPS Speedometer sells 11 in-app purchases, starting at $1.99 per 7 days and EMFMeter sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

EMFMeter holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: GPS Speedometer has 4.2K ratings behind it against 98, so its average is the more settled of the two. Written reviews complicate that: 66% of GPS Speedometer's written reviews are positive against 60% of EMFMeter'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 2 months. The most recent releases landed on October 13, 2026 and October 12, 2026 respectively.
