iPhone beta available now on TestFlight. App Store and Google Play coming soon.
For everyone else — grandparents, babysitters, teachers, school nurses — create a caregiver code. No account needed: they type it or scan its QR on the sign‑in screen.
Readings, logs, adding logs, the calculator, chat — on or off, per person.
Always on, school hours, one‑time, or paused. Outside the window, the screen locks.
One account lists every child a nurse cares for, each with their current reading.
Send a code by text or show its QR. Retire it any time.
Tap through a real day.
No carb charts. No mental math. Take a picture of the plate — Glucose Guardian estimates the carbs, fills in the calculator with the live reading, shows every step of the math, and logs it for everyone.
Packaged food? Switch to Barcode. Regulars are one tap away in Quick Lookup, and a forgotten meal can be backdated. Demonstration with sample settings (1:15 carb ratio · target 120 · correction 1:50) — not for real dosing decisions.
The calculator follows the same principles as commercial bolus calculators — and adds guardrails for the moments when families are most likely to make a mistake.
For a while after a dose, any extra correction is held — so reopening the calculator ten minutes later won’t suggest more. Carbs are always covered.
Each suggestion is capped based on body weight. If the math goes past it, the app says so and asks you to check with your care team.
When glucose is low, the app points you to fast‑acting carbs. Below target, the correction is left out.
Very high? Verify with a finger stick and check ketones. Earlier insulin not working? Check the site or pen.
If your logged doses consistently differ from suggestions, a small pattern adjustment appears as its own line. Your settings never change on their own.
Long‑acting insulin isn’t dosed from carbs. Glucose Guardian keeps meal math and basal doses separate.

{{p.msgNote}}
Readings sync on their own, with trend arrows and color‑coded ranges — and the connection quietly signs itself back in so the numbers keep coming.
Correction, carbs, active carbs, and active insulin each get their own line — so you understand the suggestion before you act on it.
Snap the plate for an AI carb estimate, or scan a package’s barcode. Your go‑to foods stay a tap away.
The app spots patterns — meal spikes, dose timing, time in range — and every insight has an “Ask AI about this” button.
Co‑guardians get full access. Grandparents, sitters, and school nurses get a code — no account needed — with only the permissions and hours you choose.
Highs, lows, and fast rises or drops — with urgent readings delivered as critical alerts, even on silent.
Sign in with Dexcom once. Readings flow in, with the latest always on the home screen.
Add the carb ratio, target, and correction factor from your doctor, and the insulins you use.
Snap the meal, see the suggested dose and every part of it, then log what you gave with one tap.
Invite co‑guardians, hand out caregiver codes, and link the doctor’s office.
Enter the carb ratio, target, and correction factor from your care team once. Every estimate uses them, and everyone in the care circle sees the same numbers.
Give your child their own view on their own phone — big, friendly, and simple. Settings stay locked behind your guardian PIN, and everything they log shows up on yours.

Turn on exactly the alerts you want — high, low, rising fast, falling fast — and set your own thresholds. Urgent readings come through as critical alerts, so they sound even when the phone is on silent.
A different sound for highs and lows, so you know which without looking.
When a reading turns urgent, you get a moment to answer “I’m OK” or “Alert them now” before your backup is paged.
For the most extreme readings, caregivers are alerted immediately — no waiting window.
Built‑in cooldowns keep one long high from buzzing every five minutes.
Share a Doctor Code and your clinic sees what you see — in a web portal built for the people who manage many patients at once.
See how the portal works ›Readings, food and insulin logs, meal photos, and A1C estimates in one place.
Urgent lows and highs, and readings that stop arriving, show up in the portal — with email alerts and a weekly patient digest.
A doctor can propose new ratios or targets. Nothing changes until a guardian reviews and approves it in the app.
Families and the care team can message right inside the app.
Export a PDF or text report with 3‑, 7‑, 14‑, 30‑, and 90‑day A1C estimates.
Follow your phone automatically, or pick Light or Dark — so a middle‑of‑the‑night check won’t light up the whole room. Switching here changes every screen on this page.
The latest beta updates, straight from the build.
The Dexcom connection quietly signs back in, so readings don’t stop overnight.
Right after a dose, extra corrections wait until that insulin has had time to work.
A more realistic insulin curve, credited only against corrections — never the meal itself.
Switch the food camera to Barcode for packaged snacks.
3‑, 7‑, 14‑, 30‑, and 90‑day estimates in exports and on the dashboard.
Your PIN now follows you to a new phone or after reinstalling.
A guided tour that spotlights each control and explains what it does.
When a new version is ready, the app tells you — just tap restart.
[One or two sentences on how you two came together to build Glucose Guardian.]
“[Your story — when your child was diagnosed, the night or the handoff that made you build this, and what you want other families to feel.]”
“[Your partner’s story — their connection to diabetes and why they joined you to build this.]”
“[Quote from a beta parent]”
“[Quote from an adult with Type 1]”
“[Quote from a school nurse]”
“[Quote from an endocrinologist or diabetes educator]”
Every suggestion shows its parts. You always see why, and you always make the call.
Ratios and targets come from your doctor. Glucose Guardian provides estimates — it never replaces medical advice.
[YOUR PRIVACY COMMITMENT — how data is stored, who can see it, and how to delete it.]
An app for families and people managing diabetes. It shows live Dexcom readings, estimates carbs from photos, barcodes, or search, suggests insulin doses with the math laid out, sends alerts, and keeps co‑guardians, caregivers, the school nurse, and the doctor on the same page.
Dexcom, through Dexcom Share. Sign in once and readings sync automatically. [OTHER CGMS — COMING LATER?]
Co‑guardians have their own account and full access — they can log, fix, and dose from anywhere. Caregivers use a code with no account, and only get the permissions and hours you choose.
No. Create a caregiver code, choose what they can see and do and when, and share it by text or QR. They enter it on the sign‑in screen. Retire it any time.
Only the primary guardian. Doctors can propose changes from the portal, but nothing changes until a guardian approves it.
No. Glucose Guardian provides estimates only and does not replace medical advice. Always follow your doctor’s instructions.
[ANDROID AVAILABILITY AND DATE.]
[PRICING DETAILS.]
Glucose Guardian is in beta on TestFlight for iPhone. Install Apple’s TestFlight app, then tap here to join the beta.
Join the beta on iPhone today, or get a note the moment Glucose Guardian arrives on Android.
Built for school nurses, teachers, aides, and camp staff.
A Caregiver account shows every student you look after — their live reading, the carbs and insulin still working, and the full view whenever their family allows it. No more calling home to ask for a number.
This is the Caregiver Menu a school nurse sees. Tap a student to open their dashboard — then check recent readings, fix a log, or snap lunch.
{{ns.lockBody}}
[Two school nurses at our daughter’s school use Glucose Guardian every day.] These are the features they told us they can’t do without.
Tap the glucose circle to see every reading before you walked in — so you’re never starting from a single number.
The log shows breakfast at home, what was given, and who gave it. Flip back a day to see how things have been going.
Typed 20 instead of 2.0? Open the entry, edit it, and save. It’s marked “Edited,” so the family sees exactly what changed.
Take a photo of the tray. Carbs are estimated and the insulin is calculated from the family’s own settings — every step shown.
The Caregiver Menu shows each student’s reading and the carbs and insulin still working — tap one to open their dashboard.
The same app runs on iPhone, Android, and iPad — including the iPad most schools already have.
“[Quote from school nurse #1]”
“[Quote from school nurse #2]”
Download the app and pick Caregiver at sign‑up — for a nurse, teacher, or aide watching over one or more kids.
Your name and, if you like, your school or clinic. No child profile, CGM, or dosing setup.
Each family shares an 8‑character access code from their Care Circle. Type it or scan its QR.
Open a student for their readings, logs, and chat — then come back to your list.
Every student’s code carries its own permissions and schedule, set by their guardian. You never see more than they’ve shared.
View readings, view logs, add logs, use the calculator, and chat — each one on or off.
A code can follow a weekly schedule. Outside it, that student shows “Locked” on your menu — no data, nothing to remember.
Meals and doses you add show “by School nurse,” so families see exactly who gave what, and when.
Each student’s chat keeps the family — and their care team — in the same thread, during your hours.
New readings, opened or closed windows, and retired codes show up on your list the moment they change.
When a student moves on, remove them from your list. The family can add you back with a new code anytime.
Yes. Each nurse, teacher, or aide signs up as a Caregiver and adds the students they look after.
From each student’s guardian, in the Care Circle section of their Dashboard. Codes are 8 characters and can be shared by text or QR.
No. Insulin settings belong to the primary guardian. A nurse can use the calculator only if the family allows it.
If the family set a schedule, the student shows as Locked on your menu until the next window opens.
No. Glucose Guardian provides estimates only and does not replace medical advice or the student’s care plan.
[PRICING FOR SCHOOLS AND ORGANIZATIONS.]
Tell us about your school, district, camp, or clinic and we’ll help you get your staff set up.
Your patients’ glucose, insulin, and meals in one place.
The Diabetes Care Portal shows what families log in Glucose Guardian — every reading, meal, and dose, and who gave it — so you can spot patterns, message the family, and propose changes they approve in the app.
No screenshots — open the actual portal in demo mode and click around. It’s loaded with five made‑up patients, needs no account, and saves nothing.
Anyone can read about the portal here. Only invited clinicians can sign in — and they only see the patients whose families linked them.
Accounts start with a license key or invite code from your organization’s administrator. A license key sets up your organization.
A patient appears only after the family shares a Doctor Code from their Glucose Guardian app and you enter it.
“Try the demo” opens the portal with five sample patients. No account needed, and nothing is saved or sent anywhere.
Your patient list puts who needs you first, with an “Attention needed” strip for changes awaiting a caregiver or just approved.
Current glucose, estimated A1C / GMI, time in range, insulin today, and the full CGM trace — on every screen.
Show or hide any card. The rest reflow, and cards open deeper tools like full trends.
See whether control is improving or slipping, with plain‑language insights on what’s driving the A1C.
Pick any day: carbs, insulin given, glucose before and after, and who logged it — parent or school nurse.
Post‑meal highs and possible under‑boluses are called out, so patterns don’t hide in the data.
Suggest carb‑ratio and correction changes and compare periods. Nothing changes until the caregiver confirms in the app.
Chat with parents — and the school nurse — right from the patient’s chart.
A built‑in assistant answers questions about the patient you’re viewing, from their own data.
Your organization’s administrator gives you a license key or invite code.
The family shares a Doctor Code from the Glucose Guardian app. Enter it, and they’re on your list.
See readings, meals, and doses as they’re logged, and message the family.
The family reviews it in the app. It takes effect only after they approve.
Clinicians with a license key or invite code from their organization. The demo is open to anyone, but it only contains made‑up sample patients.
The family shares a Doctor Code from their Glucose Guardian app. You enter it in the portal and the patient appears on your list.
You can propose carb‑ratio, correction, and target changes. They take effect only after the caregiver confirms in the app.
Yes — parents and caregivers tagged as School Nurse in the care circle can be messaged from the patient’s chart.
No. Glucose Guardian provides estimates and summaries only and does not replace medical advice.
