# Altimeter vs GPS Altimeter & Barometer

The clearest difference is ads: GPS Altimeter & Barometer at none against Altimeter's shown. GPS Altimeter & Barometer also leads on update cadence (fortnightly vs every 6 months) and review sentiment (67% vs 56%). Altimeter's advantage is ratings volume (1.3K vs 17). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Altimeter sells 3 in-app purchases, starting at $4.99 per month and GPS Altimeter & Barometer sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Altimeter against 4.8 for GPS Altimeter & Barometer. That said, the two scores are not equally well evidenced: Altimeter has 1.3K ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 56% of Altimeter's written reviews are positive against 67% of GPS Altimeter & Barometer's.
