Mr. Spike is a daily companion app for people with Type 1 Diabetes. It helps you manage low blood glucose episodes (hypoglycemia) with calm, measured, step-by-step guidance — preventing the "panic-eat-spike" rollercoaster that so many T1Ds experience. It's designed for anyone on MDI (multiple daily injections) or insulin pump therapy who wants to reduce glucose variability and rebound highs.

No! Mr. Spike works in local mode without an account. Your data stays on your device. If you create an account, your data syncs securely to our servers, which enables the AI personalization to improve your recommendations over time — and lets you restore your data if you change devices.

The Rescue Foods Library is where you define your personal go-to treatments. Mr. Spike ships with starter templates (glucose tabs, juice, honey, etc.) that you can edit. To add your own foods:

• Go to Settings → Rescue Foods Library
• Tap "Add Food"
• Enter the name, carbs per portion, and portion size (e.g., "4 glucose tabs = 16g carbs")
• Check the nutrition label on your actual product for accuracy

This is important — the more accurate your food data, the more precise your rescue plans will be.

By default, Mr. Spike uses:

• Low threshold: 70 mg/dL (3.9 mmol/L) — triggers a rescue plan recommendation
• Very low threshold: 54 mg/dL (3.0 mmol/L) — triggers a higher-dose recommendation

You can customize these thresholds in Settings → My Profile to match what your healthcare provider recommends for you.

The stepwise approach is based on widely used clinical guidance for treating hypoglycemia. The "15-15 rule" — take 15g of fast-acting carbs, wait 15 minutes, recheck — is recommended by major diabetes organizations because it prevents overcorrection and rebound highs. The biggest cause of the glucose rollercoaster is eating too much too fast. Mr. Spike's timer creates the pause your brain needs before adding more. If you're still low after 15 minutes, the app guides you to a measured second step.

All three options are effective for treating a low — the difference is the food type:

• Fast & Precise: Glucose tablets or glucose gel — the most predictable and fastest-acting. Best when you need the most control.
• Whole-food fast: 100% fruit juice, honey, raisins, dates — still fast-acting, less processed. Good everyday choice.
• Lifestyle-friendly: Minimum effective fast carbs with a structured stabilizer snack after. Better suited if you follow a lower-carb lifestyle — but note: fast carbs are still required for treating an active low.

Important: For treating an active low, avoid foods high in fat or protein (chocolate, peanut butter, etc.) as they slow down glucose absorption.

The timer is the most important feature in Mr. Spike. When you're low, panic triggers the impulse to eat more and more. The 15-minute timer gives your body time to absorb the carbs before you assess whether you need more. You can tap "Recheck Now" at any time — but we encourage you to wait the full time when possible, because it's the key to preventing rebound highs. If you have severe symptoms, always prioritize your safety and eat more if needed.

After each rescue session, Mr. Spike asks for an outcome check-in (where did your glucose end up?). Over time, it builds a picture of your personal response curve — how your glucose reacts to specific foods, amounts, activity levels, and stress. The AI then subtly adjusts your recommendations within safe bounds. For example, if you frequently rebound high after 15g, the app may suggest a slightly smaller amount next time. Changes are gradual and always kept within safe limits.

Yes, if you have a Mr. Spike account. Your data and personalization sync across all devices signed in with the same account. In local (no account) mode, data stays on a single device.

No. Mr. Spike is a decision-support tool, not a medical device. It does not diagnose, treat, cure, or prevent any disease. The recommendations are based on widely published clinical guidelines for hypoglycemia management and are intended to support informed decision-making — not replace your healthcare provider's advice. Always consult your diabetes care team for personalized medical guidance.

If you have severe hypoglycemia symptoms (confusion, loss of consciousness, inability to swallow), call emergency services (112 / 911) immediately. If available, administer glucagon. Do not rely on Mr. Spike in a medical emergency — call for help first.

For very low glucose (<54 mg/dL / 3.0 mmol/L), Mr. Spike will show an elevated recommendation and an emergency banner. Always follow the guidance of your healthcare provider in severe situations.

CGM readings (including FreeStyle Libre) can lag behind actual blood glucose, especially during rapid changes. When your glucose is dropping steeply or your symptoms don't match your CGM reading, a fingerstick blood glucose test provides the most accurate current value. Mr. Spike will prompt you to consider a fingerstick in these situations — always follow your CGM manufacturer's guidance.

Currently, Mr. Spike works with manual glucose entry. CGM integration (starting with FreeStyle Libre) is on our roadmap and coming soon. When it's available, you'll be able to connect securely via an authorized integration flow.

Mr. Spike requires iPhone running iOS 16.0 or later. We recommend keeping your iPhone updated for the best experience and latest security patches.

We're sorry for the trouble! Please try:

• Force-quit and reopen the app
• Check if there's an update available in the App Store
• Restart your iPhone

If the issue persists, please submit a support request below with as much detail as possible (what you were doing, what happened, your iPhone model, and iOS version). We typically respond within 48 hours.
