Verdict

The call

coolAltitude and Pilot Anti both sit at 5.0 stars, but that hides the real split: 100% of Pilot Anti's written reviews are positive against 60% of coolAltitude's. Pilot Anti also leads on in-app purchases (none vs 2) and price ($2.99 vs $7.99). coolAltitude's advantage is update cadence (every 3 months vs every 10 months) and ratings volume (7 vs 1). On rating, ads and device support there is nothing between them.
