Verdict
The clearest difference is rating: Altimeter at 4.7 against Compass GPS Altimeter's 4.2. Altimeter also leads on in-app purchases (none vs 5) and ratings volume (124 vs 6). Compass GPS Altimeter's advantage is ads (none vs shown) and update cadence (every 8 days vs every 2 months). On price, device support and iOS requirement there is nothing between them.
