Verdict
The clearest difference is review sentiment: Expert XAiR at 100% against ShiftPower's 61%. Expert XAiR also leads on ads (none vs shown) and monetization model (free vs ad-supported). ShiftPower's advantage is rating (4.8 vs 4.3) and update cadence (every 2 weeks vs every 3 months). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ShiftPower holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: ShiftPower has 354 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 61% of ShiftPower's written reviews are positive against 100% of Expert XAiR's, so the app with the better star average is not the one people write more warmly about.
ShiftPower ships an update every 2 weeks, Expert XAiR every 3 months. Both last shipped on November 3, 2026.
