Verdict
The clearest difference is price: My EZ Diary at Free against Prodigy's $3.99. My EZ Diary also leads on iOS requirement (15.1 vs 18.0). Prodigy's advantage is rating (4.2 vs 3.8) and update cadence (every 10 days vs every 6 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
