Verdict
The clearest difference is rating: WikEM at 4.8 against STAT EM's 4.1. WikEM also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 5 days vs every 6 weeks). STAT EM's advantage is chart position (#169 vs unranked). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. WikEM sells 10 in-app purchases, starting at $1.99 per month and STAT EM sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
WikEM holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: WikEM has 4.8K ratings behind it against 9, 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 33% of STAT EM's.
WikEM ships an update every 5 days, STAT EM every 6 weeks. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
