The free PredictBGL Logbook app is your loyal diabetes buddy. Track active insulin, blood sugar, bolus, basal, shots, food, carbs, weight, HbA1c and more. Effortless live Dexcom integration. Data is automatically synchronized to unlimited carers and your Health Care Team.

PredictBGL calculates insulin doses, tracks active insulin to avoid stacking, and uniquely, warns of hypos hours ahead. It makes dose suggestions, reminds you of meals and basal insulin, and sounds alerts for predicted hypos and for hypo follow-up.
