Verdict

The call

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.
