Verdict

The call

The clearest difference is monetization model: Microgram at free with in-app purchases against Zempy's subscription. Microgram also leads on rating (4.7 vs 4.2) and ratings volume (1.1K vs 38). Zempy's advantage is update cadence (every 3 days vs every 2 weeks) and iOS requirement (13.0 vs 17.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
