Verdict
The clearest difference is in-app purchases: Altimeter at none against UniTrip's 1. Altimeter also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.0). UniTrip's advantage is ads (none vs shown) and update cadence (every 2 days vs every 2 months). On price there is nothing between them.
