# Altimeter+ vs StackTrack

The clearest difference is price: StackTrack at Free against Altimeter+'s $1.99. StackTrack also leads on rating (5.0 vs 4.5) and update cadence (every 3 weeks vs every 2 months). Altimeter+'s advantage is ratings volume (700 vs 2) and chart position (#40 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.

StackTrack is free to download; Altimeter+ costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

StackTrack holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Altimeter+ has 700 ratings behind it against 2, so its average is the more settled of the two.

Altimeter+ ships an update every 2 months, StackTrack every 3 weeks. The most recent releases landed on October 12, 2026 and October 5, 2026 respectively.
