# Altimeter GPS & Barometer vs Compass

The clearest difference is review sentiment: Altimeter GPS & Barometer at 58% against Compass's 17%. Altimeter GPS & Barometer also leads on rating (4.6 vs 4.1) and ratings volume (2.2K vs 222). Compass's advantage is update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Altimeter GPS & Barometer sells 7 in-app purchases, starting at $2.99 per 7 days and Compass sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Altimeter GPS & Barometer holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Altimeter GPS & Barometer has 2.2K ratings behind it against 222, so its average is the more settled of the two.
