# Altimeter vs Altimeter Pro

The clearest difference is price: Altimeter at Free against Altimeter Pro's $0.99. Altimeter also leads on ratings volume (1.3K vs 9). Altimeter Pro's advantage is in-app purchases (none vs 3) and ads (none vs shown). On rating there is nothing between them.

Altimeter is free to download; Altimeter Pro costs $0.99 up front. Altimeter sells 3 in-app purchases, starting at $4.99 per month. Altimeter Pro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Altimeter against 4.7 for Altimeter Pro. That said, the two scores are not equally well evidenced: Altimeter has 1.3K ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 54% of Altimeter's written reviews are positive against 80% of Altimeter Pro's.

Altimeter ships an update every 7 months, Altimeter Pro fortnightly. The most recent releases landed on September 21, 2026 and September 10, 2026 respectively.
