Understand why your glucose does what it does.
Dia connects your day — sleep, heat, altitude, food, movement — to your glucose state and explains the why in plain English. No numbers. Just understanding that gets more personal over time.
A wellness & education app — not a medical device. Not a substitute for a CGM, glucose meter, or your care team.
You've been higher than usual since lunch.
It's warm out today, and heat can slow how quickly insulin is absorbed. You also moved less than your typical afternoon. That combination often shows up like this.
No numbers
A number tells you what. Dia tells you why.
Staring at mg/dL all day is exhausting. Dia shows no glucose numbers anywhere. Instead it speaks in plain states — so you can glance, understand, and get on with your day.
And it doesn't stop at the label. Dia connects each state to what's happening in your life and explains it in a sentence you can actually use.
“Running high since lunch — likely the heat slowing absorption.” That's the whole idea: a state and a reason, not a readout.
How it works
Two daily moments, plus the why in between.
Dia bookends your day and fills in the middle — turning scattered signals into a story you can understand at a glance.
Morning Brief
A calm summary of how your night went and a heads-up on what the day ahead may bring — so you start informed, not guessing.
Night Analysis
A look back at how the day went and the real-world factors that shaped it — heat, sleep, movement, meals — connected into one clear story.
The right-now why
When something shifts, Dia surfaces a contextual insight that explains what your state is and the factors most likely behind it.
Features
Context that compounds over time.
The longer you use Dia, the more personal its explanations become. Everything is built to help you understand — never to advise on insulin, food, or treatment.
Right-now insights
Plain-English context the moment your state shifts — what it is, and the factors most likely shaping it.
Patterns & factors
A Patterns view with time-in-range trends and factor correlations, so you can see how sleep, heat, or movement tend to line up with your states.
Ask Dia
Have a question about your patterns? Ask Dia in plain language and get a clear, contextual explanation drawn from your own history.
Learn library
A growing library of T1D science, written in plain English — the background that helps the “why” make sense.
Privacy
Your health data stays on your device.
Privacy isn't a setting in Dia — it's the architecture. The sensitive part of your data never has to leave your phone for Dia to explain your context.
Raw readings stay on device
Glucose and health readings are read on your device. Only the derived state context ever leaves it — never your raw numbers.
Never sold, never tracked
No ads, no third-party ad tracking, no selling of your data. There are no analytics trackers on this site, either.
