Spike - Blood Sugar Tracker

Understand your blood sugar, whether you use a fingerstick meter or a CGM.

Spike brings glucose readings, meals, carbs, and trends together in one clear place. Log a fingerstick reading in seconds or connect compatible CGM data through Apple Health. Scan a meal with AI, see carbs and sugar, and understand the response that followed.

BUILT FOR METER AND CGM USERS

Use Meter Mode for manual readings or CGM Mode for readings shared through Apple Health. If you start wearing a sensor later, switch modes without losing your meal or glucose history.

AI MEAL SCANNER

Take a photo of your meal to estimate calories, carbs, sugar, fiber, protein, and fat. Review and edit the result before saving.

GLUCOSE AND MEAL IMPACT CURVES

See your day on one clear glucose curve. Connect meals with the readings that followed and identify patterns worth paying attention to.

SEVEN AI MEAL INSIGHTS

Go beyond calories with insights for satiety, nutrient density, inflammation, glycemic load, hydration, digestion, and timing.

TRENDS THAT MAKE SENSE

Follow daily and weekly changes in your readings, meals, carbs, and habits. See progress over time without digging through complicated charts.
