# Altimeter X vs Altimeter+

The clearest difference is rating: Altimeter+ at 4.5 against Altimeter X's 2.5. Altimeter+ also leads on update cadence (every 2 months vs every 28 months) and ratings volume (707 vs 2). Altimeter X's advantage is price ($0.99 vs $1.99). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

Altimeter X costs $0.99 and Altimeter+ $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Altimeter+ holds the better App Store score, 4.5 against 2.5. That said, the two scores are not equally well evidenced: Altimeter+ has 707 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 84% of Altimeter X's written reviews are positive against 80% of Altimeter+'s, so the app with the better star average is not the one people write more warmly about.

Altimeter X ships an update every 28 months, Altimeter+ every 2 months. Both last shipped on October 21, 2026.
