CGMSIM lets you create a virtual Type 1 Diabetes subject, that you'll treat 24/7 with meals, multiple daily insulin injections (MDI) or a virtual insulin pump (CSII - continuous subcutaneous insulin infusion). Your goal is to maintain your virtual subject's glycemia in the treatment range 70-180 mg/dl (3.9 - 10 mmol/l) at least 70% of the time, with as few low glucose values as possible. Optional hypo- and hyperglycemia are delivered as push notifications and email alerts. CGMSIM imports your Fitbit® activity tracker's or Google Fit® activity data (steps, heart rate), which influence your subject's glycemic status. The CGM trace is displayed in Nightscout, where success reports can be generated.

Verdict
The clearest difference is update cadence: CGMSIM at every 2 months against IST Quiz App's every 12 months. IST Quiz App's advantage is iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
