Log a chicken burrito at 12:40. Three hours later, spike shows you the whole story: where your glucose started, how high it went, and how long it took to come back down.
No guesswork. No spreadsheets. Just answers.
+52 mg/dL spikeIf you wear a CGM, you're two minutes from knowing what actually spikes you.
Stelo, Dexcom, Libre, or Lingo. If it writes to Apple Health, spike reads it. One permission screen, no extra hardware, no manual syncing.
Point your camera at the plate. AI identifies the food and logs calories, carbs, protein, and fat in seconds. Edit anything it gets wrong.
A few hours later, your answer arrives: the full glucose curve, your peak, and how long you took to return to baseline. Every meal, automatically.
Not another calorie counter. spike exists to answer one question: what does food do to your body?
Baseline, peak, time to peak, and time back to baseline: a full response analysis for every meal you log.
When your meal's data arrives, spike notifies you with the verdict: steady response or spike, with the exact number.
Time in range, daily average, and every meal marked on your day's glucose curve. Tap any meal to drill in.
Photo, voice, or search. Logging takes seconds. Full macros and nutrients, editable down to the ingredient.
The standard 70–180 mg/dL range out of the box, adjustable if you and your care team use different targets.
Glucose data stays in Apple Health on your device. spike reads it with your permission and never sells or shares your health data.
Your sensor costs enough. spike adds the answers for a fraction of it. Free trial included, cancel anytime.
Every plan includes everything: per-meal glucose curves, spike alerts, AI meal logging, and your daily glucose story. Works with the CGM you already own. CGM sensor sold separately by Dexcom or Abbott.
Any CGM that shares data with Apple Health: Dexcom Stelo, Dexcom G6/G7, FreeStyle Libre, and Lingo. Stelo and Lingo are available over the counter in the US for adults 18+, no prescription needed.
Stelo's own app shows your current reading. spike is the analysis layer on top: it reads Stelo's data from Apple Health and turns it into per-meal answers, showing the glucose curve, peak, and recovery time for every meal you log. If you bought a Stelo to learn what food does to your body, spike is the app that answers that question.
Those services sell programs that bundle sensors, coaching, and an app, typically at $100 or more per month. spike is bring-your-own-CGM: buy a sensor like Stelo over the counter, connect it through Apple Health, and spike does the meal-by-meal analysis for $129.99 a year (or $19.99 a month). Same core insight, no program commitment, at a fraction of the cost.
No prescription is needed for OTC sensors like Stelo. You'll get the most from spike with a CGM connected, but meal logging with AI nutrition analysis works either way.
CGM apps share data with Apple Health on a delay. Stelo, for example, delivers readings about 3 hours behind its own app. spike is built around this: it analyzes each meal's full response once the data arrives and notifies you. For your live number, check your CGM's own app; for what it means, check spike.
Yes. Glucose readings are read from Apple Health on your device with your explicit permission. We never sell your data and never use your health data for advertising. See our privacy policy for the details.
No. spike is a wellness app for understanding how food affects your glucose. It doesn't diagnose, treat, or manage any medical condition, and it's not a substitute for medical advice. If you have diabetes or another condition, work with your care team.
spike is $129.99 per year (about $10.83/month, billed annually) or $19.99 per month, with a free trial so you can see your first meal responses before paying. Compared to what you spend on the sensor itself, spike costs a fraction, and it's the part that turns the data into answers.
spike is iOS-only today. Android is on the roadmap. Email [email protected] and we'll let you know when it's ready.
Your CGM is already collecting the data. spike turns it into answers.
