New to CGMs? It's the patch sensor on your arm or belly that reads glucose every 5 minutes — Dexcom or FreeStyle Libre.

The problem

Your endo sees a snapshot.
You live the whole story.

A 15-minute appointment, every 3 to 4 months, based on the last two weeks of data. No context. No memory. No why.

01

Every 3 to 4 months

You sit down with your endo. They look at the last two weeks. Maybe something catches their eye. A small pump adjustment is made.

02

No context, no memory

They don't know you cycled Saturday and your glucose was off Sunday. Or that you slept poorly for a week. Or what you actually ate on Wednesday.

03

You leave with a guess

A small tweak. No way to know if it worked until the next visit, months later. The loop is too slow.

What you actually receive

Continuous eyes. Three deliverables. All automatic.

No dashboards to check. No app to open. Glyca runs quietly in the background and sends structured insights on Telegram, at the moments that matter.

Morning Brief Every day · 10:00 AM
Good morning, Satish ☀️

A solid night — overnight TIR 90%, mean 118 mg/dL, no lows.

Worth watching today
Your 06–12h window has averaged 42% TIR this week. Pre-bolusing 10 min earlier worked on Tuesday — worth another go at breakfast.
📊
Weekly Pattern Scan Every Sunday · 7:00 PM
Week in review. 3 patterns found.

1. Morning gap persists
90% TIR overnight versus 42% TIR mornings, every day. Something changes the moment you wake up.

2. Control-IQ overriding 97.8%
Your manual basal profile is almost never what's actually running. The system is compensating for a mismatch.

3. Evening I:C overcorrecting
Glucose dropping 95 mg/dL below baseline at 3h post-dinner across 8 meals. Worth discussing.
📋
Endo Discussion Document Before every appointment · shareable link
14-day report. 5 discussion points for your endo.

Summary
TIR: 58% · TAR: 34% · TBR: 8% · GMI: 7.2% · Mean: 162 mg/dL

Discussion points
1. Morning TIR gap: 90% overnight versus 42% mornings. Could dawn basal profile explain this?
2. Control-IQ override rate: 97.8%. Should we update the manual profile?
3. Evening I:C ratio: glucose 95 mg/dL below baseline at 3h post-dinner. Possible overcorrection.
4. Sleep correlation: TIR is 24 points higher on days following 7+ hours of sleep.
5. Two identical-carb drinks caused +103 vs +270 mg/dL spikes. Pre-bolusing strategy?

Real output · generated from 5 days of data

What the AI actually surfaces.

Genuine outputs from a real user. Every insight links to specific data and ends with a question for the endo. (Pump-mode examples are in pilot today.)

Pattern scan · Sunday

Your worst window is every morning.

90% TIROvernight 00 to 06h
→
42% TIRMorning 06 to 12h

A 48-point drop between overnight and morning performance, consistent across every day of the week. Overnight Control-IQ keeps things stable. Something changes the moment you wake up.

💬 Question for your endo "My mornings are at 42% TIR every day while my nights are at 90%. Could my morning I:C or dawn basal profile explain this?"
Pump analysis · 7 days

Control-IQ is overriding your manual settings 97.8% of the time.

Over the last 7 days, 97.8% of your basal insulin was delivered by Control-IQ automation, not your programmed profile. That means the manual basal you set is almost never what's actually running. The system is compensating for a mismatch.

💬 Question for your endo "Control-IQ is overriding my manual basal 97.8% of the time. Should we update the manual profile to reflect what CIQ is actually delivering, so it has a better starting point?"
Meal response · 3h post-meal

Same carbs. Completely different spikes.

Starbucks caramel coffee 20g carbs +103 mg/dL
Iced latte 20g carbs +270 mg/dL

Both logged as 20g carbs. Both drinks. One spiked 2.6× more than the other. Fat content, caffeine, or a different starting glucose. Something explains the gap, and it's not the carb count.

💬 Question for your endo "Two similar drinks with the same carb estimate caused +103 vs +270 spikes. Could fat or caffeine content be this significant, or should I be pre-bolusing for these?"
I:C ratio analysis · 16 meals

Your afternoon and evening I:C ratios may be too aggressive.

59 mg/dL belowMidday meals at 3h
95 mg/dL belowEvening meals at 3h

Across 16 analysed meals, glucose was dropping well below the starting value by 3 hours post-meal. Especially at dinner. This suggests the bolus is overcorrecting. Not a conclusion, but a pattern worth discussing.

💬 Question for your endo "My glucose is 59 mg/dL below at midday meals and 95 mg/dL below at dinner at 3h post-meal. Should we adjust my I:C for those time blocks?"

⚠️ These are observational patterns, not clinical instructions. All outputs are discussion documents for use with your healthcare provider.

Who it's for

Built for patients.
Useful for endocrinologists.

🩸 For T1D patients

  • All you need is a CGM — Dexcom Share or FreeStyle Libre
  • Know what's happening between appointments, not just at them
  • Show up with specific patterns and questions, not a graph
  • Feels like someone is watching your data so you don't have to
  • Photo meals, insulin pen, pump and more wearables coming soon

🏥 For endocrinologists

  • Patients arrive with a pre-digested 14-day summary, not a raw graph
  • Hidden cross-source patterns surfaced: exercise, sleep, meal type
  • Discussion questions auto-generated from the patient's real data
  • No portal to log into. A shareable link, readable in any browser
  • More time spent on decisions, less on interpreting data
What's next

None of these are required to use Glyca. They just make the patterns richer.
