Verdict
The clearest difference is price: WikEM at Free against EBMcalc Complete's $9.99. WikEM also leads on rating (4.8 vs 3.0) and update cadence (every 5 days vs every 6 months). EBMcalc Complete's advantage is in-app purchases (none vs 10) and iOS requirement (10.0 vs 15.1). On review sentiment, ads and device support there is nothing between them.
