Three tabs to help you notice patterns, remember what you ate, and try a small change.
Activity
Meals + workouts.
One timeline.
Your lunch and your post-lunch walk belong in the same story. See logged meals and Apple Health workouts together, then explore their glucose responses.
Connect food, movement, and glucose. Use Apple Health workout data to estimate its impact on glucose. Patterns from your history, not proof of cause.
Quests
Turn curiosity into a habit.
Try the free Post-meal walk Quest: five walks in seven days. Follow your progress, then review a recap of what you learned.
App screenshots use illustrative sample data. Your patterns and results will vary.
A little more delightful

Make a prediction. Meet your response.
How high do you think your glucose will go after this meal? Lock in your own peak prediction while you wait for CGM data, then compare it with the observed response. A small, playful way to get to know your patterns.
Predictions are for learning, not medical guidance.

My story
Why I built SpikeSmart.
I’ve been living with type 2 diabetes for over a decade.
The CGM apps I tried were great at showing me real-time glucose. But meal logging felt boring and tedious, and the experience never felt personal enough for me.
I wanted insights into the questions that mattered in my own life: what works better for me, long walks or earlier evening meals? How many cheat meals can I have each week and still hit my A1c goal?
I wanted helpful ideas for things to try, and a structured way to see how my actual blood glucose responded. That’s why I built SpikeSmart. I’ve also tried to make meal logging more fun with memorable images of whole meals.
Using SpikeSmart has personally helped me bring my A1c down from 7.6% to 5.6%. I’m building it to make learning from my own meals, movement, and everyday habits feel more personal and practical.
This is my personal experience. Everyone’s results are different.
