Verdict

The call

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.

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.
