Verdict
The clearest difference is review sentiment: みんなde心電図 at 97% against m3.com's 36%. みんなde心電図 also leads on ads (none vs shown) and rating (5.0 vs 4.6). m3.com's advantage is in-app purchases (none vs 10) and ratings volume (37 vs 1). On price, update cadence, device support and iOS requirement there is nothing between them.
