Verdict

The call

ShiftPower and Expert XAiR both sit at 4.8 stars, but that hides the real split: 100% of Expert XAiR's written reviews are positive against 61% of ShiftPower's. Expert XAiR also leads on ads (none vs shown) and monetization model (free vs ad-supported). ShiftPower's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (348 vs 4). On price, rating, in-app purchases and device support there is nothing between them.
