Mr. Spike gives you calm, measured, step-by-step guidance the moment your glucose drops — and learns what works for you, every single time.
When your glucose drops fast, your brain enters fight-or-flight mode. Rational thinking goes out the window.
You grab everything in sight. Candy, juice, bread — all at once. Way more than you actually needed.
The overcorrection sends you sky-high. Now you need to correct that. The rollercoaster continues.
Mr. Spike combines clinical guidance, behavioral psychology, and AI personalization to break the panic cycle — and keep you in range.
Get exact gram-by-gram carb instructions based on your glucose, trend, and personal history. No more guessing under pressure.
A calm countdown prevents you from eating more before your first treatment even kicks in. One measured step at a time.
Every rescue session teaches Mr. Spike your unique response. Suggestions improve automatically — the more you use it, the smarter it gets.
Going for a run? High stress day? Mr. Spike factors in your current activity level so the plan actually fits your real situation.
Choose from Fast & Precise, Whole-food, or Lifestyle-friendly options. Build your personal rescue foods library from the foods you actually eat.
See your rebound trends, your most reliable treatments, and your progress over time. Understand your body like never before.
