Spike - Blood Sugar Tracker
Glucose log for CGM & meter
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Track your blood sugar with or without a CGM. Log fingerstick readings, scan meals with AI, and see exactly which foods spike you.
Every meal moves your blood sugar. Spike shows you exactly how, and what to do about it.
Spike is the blood sugar tracker for real life. Whether you check with a fingerstick meter or wear a CGM (Stelo, Libre, Lingo, Dexcom), Spike turns your readings into answers: log a reading, log your meal, and see exactly what spiked you.
No CGM yet? Start today anyway. Scan any meal with AI to get carbs, sugar, fiber and macros instantly, see its predicted glucose impact, and connect a sensor whenever you're ready. Your history carries over.
You are already investing in a sensor. Spike makes that investment pay off.
WHY SPIKE
Your sensor's built-in app shows you numbers. Spike answers the questions that matter:
- Why did I spike to 160 after a "healthy" breakfast?
- Which of my meals cause my biggest spikes?
- Why is my glucose high in the morning before I eat anything?
- What is different about my weekends?
- Is my average trending in the right direction?
WHAT YOU GET
AI GLUCOSE INSIGHTS
Spike analyzes your glucose curves and explains your spikes in plain English, identifying the patterns behind them, meal timing, food combinations, sleep, stress, and more.
SPIKE DETECTION & ANALYSIS
Every significant spike is automatically detected, scored, and logged. See your biggest spikes of the day, week, and month, and learn what triggered them.
WEEKLY SPIKE REPORT
Every week, Spike delivers a personal report: your average glucose, time in range, biggest spike, weekday vs. weekend patterns, and one clear suggestion to try next week.
PATTERN LIBRARY
Spike remembers how your body responds. Over time it builds your personal library of known spikers and safe meals, so past sensor sessions keep working for you even between wears.
TRENDS THAT MATTER
Time in range, glucose variability, daily averages, overnight patterns, and morning readings, all tracked over weeks and months, not just the last 24 hours.
WORKS WITH YOUR SENSOR
Spike reads glucose data through Apple Health. Compatible with Dexcom Stelo, Abbott FreeStyle Libre, Lingo, and any CGM that syncs to Apple Health. No extra hardware, no manual logging required.
WHO SPIKE IS FOR
Spike is built for people wearing a CGM to understand their metabolic health: biohackers, prediabetics tracking their progress, athletes optimizing fuel, and anyone who bought a Stelo or Libre and wants more than a line on a graph.
Spike is a wellness app, not a medical device. It does not provide medical advice, diagnosis, or treatment. Always consult a healthcare professional for medical decisions.
YOUR DATA STAYS YOURS
Your glucose data is read securely from Apple Health with your permission. We never sell your health data.
Download Spike and find out what your glucose has been trying to tell you.
