Verdict
The clearest difference is rating: Stadia Altimeter at 5.0 against AvNav's 4.2. Stadia Altimeter also leads on in-app purchases (none vs 1) and iOS requirement (11.0 vs 16.6). AvNav's advantage is update cadence (every 10 days vs every 9 months) and ratings volume (5 vs 1). On price, ads and device support there is nothing between them.
