Verdict
The clearest difference is price: WikEM at Free against QuickEM's $9.99. WikEM also leads on update cadence (every 5 days vs every 2 months) and ratings volume (4.7K vs 10). QuickEM's advantage is review sentiment (91% vs 54%) and chart position (#60 vs unranked). On ads, in-app purchases, device support and iOS requirement 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
WikEM is free to download; QuickEM costs $9.99 up front. WikEM sells 10 in-app purchases, starting at $1.99 per month and QuickEM sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
WikEM holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: WikEM has 4.7K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 54% of WikEM's written reviews are positive against 91% of QuickEM's, so the app with the better star average is not the one people write more warmly about.
WikEM ships an update every 5 days, QuickEM every 2 months. The most recent releases landed on October 13, 2026 and October 8, 2026 respectively.
