IN PROGRESS · 2026

A softer way
to carry diabetes.

Stillra learns your patterns over time — your nights, your meals, what you say — and weaves it together into a picture of you. For you around the clock. For your doctor when it matters. Built by someone who lives with it too.

Stillra: Today view with the morning brief
INSIDE THE APP

Three calm surfaces.

Frida weaves together your day. Stillra translates it into meaning. You read, you talk, you pack for the doctor — in ten seconds each.

Today

The value right now. What's happened since yesterday. No graph that screams — just what belongs here.

Frida at the center of a web — the night, patterns, feeling, doctor's brief, body, what you said, meals, stress

Frida sees everything. Stillra weaves it together.

Nothing is passed on. Everything becomes whole.

Chat

Questions hard to put into words. A conversation, not a command line.

Doctor's visit

Things you want to say — gathered for you. 15 minutes become meaningful.

More

Settings, loved ones, privacy. Nothing hidden — just not in the way.

"What I wanted to build was the voice I missed on day one. Not another data app — a presence that understands what it means to live in a body demanding constant attention."

THE DOCTOR'S BRIEF

This is why Stillra exists.

Not more data.
Better visits.

Your doctor has 15 minutes. They open Clarity, see numbers, adjust a row, say goodbye.

Stillra helps you use those minutes. Two weeks of your everyday — packed on a page the doctor reads in 90 seconds. The patient's voice first. The data after.

Not summarized data. Patterns Stillra has learned about you specifically, translated into the patient's voice.

Here's an example. Not a template — a patient's voice.

No recommendations. No diagnoses. Just your foundation.
DOCTOR'S BRIEF · MAY 2026

Things you want to say
— gathered for you.

PATTERN
The numbers aren't the problem anymore. It's what they cost to keep there.
WHAT WORKS
When I eat the same breakfast every day. Boring, but safe.
WHAT THE NIGHTS CRIED OUT
11 wake-ups. One at 2.8 mmol. Am I pressing too hard?
WHAT YOU CARRY
My HbA1c is falling, but I feel worse. Worry from both sides.
QUESTION YOU WANT TO ASK
What are these numbers actually costing me?
MEALS

We start where you are.

Healthcare measures success by how exactly we count. We measure success by how long we can keep going. These are two different things.

Stillra picked a side. Photograph what you eat — or write what it is. Frida gives you a range that learns from your patterns — shows you why it matters, and lets you decide what to do with the answer.

Counting can come later, if you want. Or never.

THE MORAL DETAIL

When someone writes something heavy,
it actually goes quiet.

What you wrote stays with me. You don't have to carry this alone.

If it feels too heavy right now:

  • Mind — 901 01, 24/7 (for heavy thoughts)
  • 1177 — healthcare guidance, 24/7
  • 112 — if you're in immediate danger

I'm here if you want to write more. No pressure.

Frida paused a little longer here.

No banners. No 112-buttons. No modal that opens and screams. Just presence and resources, softly shadowed. This is the product's moral center.

CARL'S PORTRAIT
(natural light, looking inward)
WHY STILLRA

When data becomes just data.

When data has no context, it's just numbers on a screen. And numbers without meaning do one thing: they make you feel guilty.

Highs, you did something wrong. Lows, you did something wrong. Good HbA1c, you don't know why. Bad HbA1c, you don't know why. Everything is wrong, always, in different ways — and you stand alone with it.

Stillra stops measuring. She translates. A night becomes a story. A week becomes a pattern. Six months become something you can hold up and say: "this is what my life looks like."

Saturday morning. 6 a.m. I woke up from low blood sugar after a week averaging three and a half hours of sleep.

I'm okay. I'm so used to it.

But I'm sad. Because I've been holding my blood sugar steady. Pressed, tweaked, cared 10x. Heard the doctor's words about risks echo for the 7,011th time. It's been a long time since my numbers looked this good.

But do I feel better? No. Because I'm sacrificing my whole everyday, my soul. To worry from both sides.

This is why Stillra exists.

Healthcare measures HbA1c. Apps draw graphs. Alarms scream. But no one asks: how was the night, really? What are you carrying?

Stillra is the attempt to build the voice I missed. Inspired by my mother — she who listened without scolding, who knew when something was worth saying and when silence was right.

It's not a medical device. It's not a substitute for your doctor. It's a calm presence around the clock — and an agenda-bearer when you meet healthcare every six months.

— Carl

WHAT STILLRA IS NOT

Stillra is not everything.

Not a replacement for your care. Not a coach. Not an optimization-trick factory. Not a chatbot pretending to be a person.

Not a place where "improvement" means lower HbA1c, no matter what it costs you.

THE PHILOSOPHY

Three things that guide every choice.

Patient's voice, anchored in data

The data is the framing, not the protagonist. You are the protagonist. The brief reads as your letter to the doctor — not the other way around.

Never dosing advice

Stillra doesn't say "take 2 units." She doesn't suggest medication switches. She doesn't give diagnoses. That work belongs to healthcare — we do other things.

Calm before effective

An empty screen is not a failure. Silence is often the right answer. Stillra wakes you only when it really needs to.

THREE DEPTHS OF PRESENCE

Choose how much she carries with you.

Same voice. Same soul. Different depths.

Shield

79 SEK / month

For those who just want it quieter.

Fewer alarms. Only the ones that need you. Wherever you have a pod in your ear — at work, in the meeting, on the run, on a walk — Frida says the number softly. And the night is silent when nothing's happening.

  • Smart alarm filtering
  • Sleep Mode
  • Frida's voice in your headphones
  • Companion Guard
  • The whole app's design

Presence

399 SEK / month

For those who want to be held.

Frida, fully present. Chat when something's hard to put into words. Meal analysis from a photo. Loved ones who follow safely. For those who feel the everyday between doctor's visits is too far apart.

  • Everything in Brief
  • Chat with Frida
  • Meal analysis (photo or text)
  • Loved-ones sharing
  • Proactive presence
QUESTIONS?

Here I am.

Question that's not here? Write to me directly — I read every email myself. This is still small enough to be personal.

stillra@proton.me
Is Stillra a medical device?
No. Stillra gives no dosing advice, no diagnoses, no treatment decisions. All of that belongs to your doctor. Stillra is a calm presence that helps you read your own data and prepare for your doctor's visits.
Which CGM systems work?
Dexcom (G6, G7, ONE+) via Dexcom Share, and FreeStyle Libre (2, 3) via LibreLinkUp. Both connect from inside the app — no extra accounts.
Where is my data stored?
Supabase in Frankfurt, EU region. AES-256-GCM encryption on CGM credentials. No AI models are trained on your data. You can export or delete everything whenever you want.
Do I need to pay from day one?
The Shield tier (79 SEK) is free during the first month for the waitlist. Brief and Presence have a seven-day trial. No auto-renewal before you've said yes.
Can my loved ones follow my values?
Yes — in the Presence tier. You invite them, you set Guard Mode rules for what they see and when they're alerted. They get no dosing advice, just presence.
What happens if Stillra can't find the right words?
Then she says so. We have an explicit fallback for days when she can't land in text — short, honest, without emptiness. "I couldn't find the right words today. Sleep well." That's safer than text that doesn't ring true.
THE WAITLIST

When it opens,
it opens for you first.

We're waiting on Apple. When they're done you'll get an email — no noise, no newsletter.
