Verdict
The clearest difference is iOS requirement: Power Queen at 13.0 against BrightEMS's 15.0. On price, rating, review sentiment and ratings volume 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.
Power Queen holds the better App Store score, 2.7 against 2.5. Both are backed by a comparable volume of ratings — 15 and 43 respectively. Written reviews complicate that: 29% of BrightEMS's written reviews are positive against 25% of Power Queen's, so the app with the better star average is not the one people write more warmly about.
BrightEMS ships an update fortnightly, Power Queen every 3 weeks. The most recent releases landed on November 12, 2026 and November 8, 2026 respectively.
