Verdict
The clearest difference is rating: WikEM at 4.8 against MobilEM's 3.6. WikEM also leads on update cadence (every 5 days vs every 2 months) and ratings volume (4.7K vs 39). MobilEM's advantage is chart position (#44 vs unranked). On price, ads, in-app purchases and monetization model 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. WikEM sells 10 in-app purchases, starting at $1.99 per month and MobilEM sells 12 in-app purchases, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.
WikEM holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: WikEM has 4.7K ratings behind it against 39, so its average is the more settled of the two. Written reviews point the same way: 54% of WikEM's written reviews are positive against 45% of MobilEM's.
WikEM ships an update every 5 days, MobilEM every 2 months. The most recent releases landed on September 23, 2026 and September 20, 2026 respectively.
