Questions, answered plainly

Adults who've been told their A1c or fasting glucose is in the prediabetes range and want to see how meals, sleep, activity and stress show up in their numbers between lab tests.

It isn't designed for type 1 diabetes, insulin use or pregnancy. If any of those apply, your care team should lead.

No. A CGM gives the richest picture, including meal-by-meal rises. You can also use a fingerstick meter or type in readings by hand. Lab results, meal logging and the morning energy check-in all work without a sensor.

Any CGM or meter whose app writes blood glucose readings to Apple Health. Look for an Apple Health option in your device app's settings. PeakRoutine brings in your past readings on first sync, then keeps checking for new ones.

Android is coming soon. For now PeakRoutine is on iPhone, where it reads your glucose, sleep and activity from Apple Health.

PeakRoutine is free to start. PeakRoutine Pro is an optional in-app subscription, monthly or yearly; the App Store shows its price in your currency before you subscribe. It's billed through your Apple ID, and you can cancel anytime in your iPhone's Settings.

No. GMI (glucose management indicator) is an estimate calculated from at least 10 days of sensor data. HbA1c is a lab test that reflects roughly the past three months. They often differ, for reasons that include how long your red blood cells live. PeakRoutine shows both side by side and labels GMI as an estimate.

It's the middle sensor reading between 5:00 and 8:00 AM. It's a useful daily marker, but it isn't a true fasting test, so we don't call it fasting glucose.

When you log a meal and have sensor readings around it, PeakRoutine measures the rise: the highest reading in the two hours after the meal, minus where you started. If you've eaten a shared food before, you can see both days side by side with what else was different, such as sleep, a walk after eating or a stressful day. One comparison is a starting point for curiosity, not a rule.

Take a photo of your report or choose the PDF. PeakRoutine reads the values for the tests it tracks and shows them to you to check and edit before anything is saved. You can also enter values by hand. It tracks 14 tests, including HbA1c, fasting glucose, fasting insulin, cholesterol, kidney and liver markers, hemoglobin, ferritin, TSH and vitamin D.

No. We repeat the high or low flag printed by your lab, and we don't add our own judgment. Your clinician is the right person to interpret your results.

No. PeakRoutine is a wellness app. It doesn't diagnose, treat or prevent any condition. Your clinician diagnoses and manages prediabetes; we help you see your own data between visits.

No. Fixed safety rules stop the coach from suggesting starting, stopping or changing any medicine or supplement. It will point you to your pharmacist or doctor and can help you write down your question.

If you tell the coach about a fasting reading of 126 mg/dL or more, any reading of 200 mg/dL or more, a reading under 70 mg/dL, or an A1c of 6.5% or more, it will tell you it's worth raising with your clinician. If you describe urgent symptoms, it will tell you to get help now. In an emergency, call 911.

We don't make that claim. Lifestyle change is what clinicians recommend for prediabetes, and PeakRoutine helps you see how your habits show up in your own data. Whether and how your numbers change is something to track with your clinician.

No. We never sell your health data and never use it for advertising. Your data is encrypted in transit and at rest.

The file stays on your iPhone. It's read once to fill in the values and isn't stored on our servers. Only the values you confirm are saved.

AI features send the data they need to Anthropic, our AI provider. The coach and lab report reading only work after you turn on AI personalization, and you can turn it off at any time. See our approach to your data.

Yes. You can delete your health background in the app, or delete your account and its data.
