# Coordinates vs Altimeter Pro

The clearest difference is price: Coordinates at Free against Altimeter Pro's $0.99. Coordinates also leads on ratings volume (6.6K vs 9). Altimeter Pro's advantage is in-app purchases (none vs 6) and ads (none vs shown). On rating, update cadence, device support and iOS requirement there is nothing between them.

Coordinates is free to download; Altimeter Pro costs $0.99 up front. Coordinates sells 6 in-app purchases, starting at $1.99 per month. Altimeter Pro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Coordinates against 4.7 for Altimeter Pro. That said, the two scores are not equally well evidenced: Coordinates has 6.6K ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 63% of Coordinates's written reviews are positive against 80% of Altimeter Pro's.

Coordinates ships an update monthly, Altimeter Pro fortnightly. The most recent releases landed on September 23, 2026 and September 10, 2026 respectively.
