Verdict
The clearest difference is in-app purchases: Dolphin at none against Glucose | Blood Sugar Tracker's 10. Dolphin also leads on rating (5.0 vs 4.6) and update cadence (weekly vs every 3 weeks). Glucose | Blood Sugar Tracker's advantage is ratings volume (29K vs 1) and chart position (#14 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.
