Three taps from plate to peace of mind.
Most meals take five seconds. Edit anything you want — every estimate is yours to override.

Calculate
We pull your current BG from Apple Health, factor in IOB and COB, and run the standard bolus formula — visible to you, every time. You stay in charge of the dose.
Formula
(52 ÷ 10)
+ ((7.2 − 6.0) ÷ 2.5)
− 0.4
= 5.2 + 0.48 − 0.4

Log

What ships in V1
Six new features in the latest build.
All shipped honestly. All inside the diabetes-grade carve-out.
New in V1
Suggestion cards that read your day
Workouts, sleep, sustained heart rate, post-meal trends — Dia AI watches Apple Health and surfaces lifestyle context, never a number of units. Stays inside the Clinical Decision Support carve-out.
New in V1
The view your endo wishes you brought
Time in Range, estimated A1C, GMI, mean glucose, dose totals, top spike foods, and pattern flags — exported as a one-page clinician PDF or raw CSV. For the 15-minute appointment that should have been an hour.
New in V1
Hey Dia, 45 grams of carbs
Speech recognition routes to a tight Claude prompt that parses natural language into structured nutrition data. Brand-specific items resolve (a 'Starbucks grande mocha' becomes 480g · 44g carbs).
New in V1
Three small wins in one
Save any meal as a reusable recipe with portion math. Tag meals with custom labels for smart search. Every scan now includes glycemic index and load — high-GI items flagged in amber, not red.
Who it's for
One app. Four very different lives.
Diabetes is not one disease. Dia AI adapts to your shape of it.
~2M people in the US
For Type 1s who carry math in their pocket.
Snap a meal, see your IOB, hit one number. Built for the daily reality of Type 1 — multiple daily injections or a pump, carb counting at every meal. We do the arithmetic visibly, with your ratios, never as a recommendation. You stay the decider.
- Bolus calculator with your I:C, ISF, target, IOB

About
Built by one Type 1, for the daily reality of diabetes.
Jacob Sprake
Founder · SPR Labs
Why I'm building this
I'm Jacob, founder of SPR Labs. I don't have diabetes myself — but one of my closest teammates does. Every design decision in Dia AI got pressure-tested against the real daily reality of life on insulin: the half-cooked carb estimates at a restaurant, the panic-check at 3am, the awkward dose math during a workout.
We're building Dia AI because diabetes management software in 2026 still feels like 2014. The 38 million Americans — and 537 million people worldwide — who live this every day deserve software that feels like Apple built it.
I've built 28+ apps at SPR Labs. This is the one that matters most.
“The fastest way to log a meal should not take 30 taps. Now it takes one.”
