Verdict

The call

The clearest difference is in-app purchases: Diary at none against Wellmetry's 2. Diary also leads on ratings volume (1.7K vs 4) and iOS requirement (12.0 vs 17.0). Wellmetry's advantage is ads (none vs shown) and rating (5.0 vs 4.5). On price, update cadence, monetization model and device support there is nothing between them.
