Verdict
The clearest difference is price: SympNote at Free against Diabetic's Diary's $0.99. Diabetic's Diary's advantage is review sentiment (100% vs 83%) and update cadence (every 8 days vs every 3 weeks). On ads, in-app purchases, monetization model and device support there is nothing between them.
