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

Overnight (00:00 – 06:00)
TIR: 90% · Mean: 118 mg/dL · Lows: none
Control-IQ was active all night. No interventions needed.

Today's focus
Your morning window (06–12h) has been averaging 42% TIR this week. Watch for post-breakfast spikes — pre-bolusing 10 min earlier helped on Tuesday.
📊
Weekly Pattern Scan Every Sunday · 7:00 PM
Week in review — 3 patterns found.

1. Morning gap persists
90% TIR overnight → 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 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 → 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 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?

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

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

🗓️

Every 3–4 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.

📄

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.

🤷

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.

Continuous eyes.
One weekly report.

An AI that runs quietly in the background — watching your glucose every 5 minutes, tracking your meals, workouts, and sleep, and finding the connections you'd never spot manually.

🔗

Connects the dots you can't

Glucose + meals + workouts + sleep + pump data — all in one place. When you cycle on Saturday, it watches what happens Sunday. It finds the patterns that are invisible in a 15-minute appointment.

📋

Pre-appointment report, auto-generated

Every two weeks, a structured discussion document is ready: what changed, what the data suggests, and 3 specific questions to ask your endo. You show up with evidence — not guesses.

📸

Photo meal logging + glucose response

Snap a photo of your food. AI estimates carbs. Three hours later, it tells you exactly how your body responded — building a personal library of what foods do to your glucose over time.

🌙

Daily morning brief

Every morning before you get up: how last night looked, what to watch today, one specific thing worth noticing. Not a wall of numbers. One insight, delivered in plain language.

What the AI actually surfaces.

These are genuine outputs from a real user — not marketing copy. Every insight links to specific data and ends with a question for the endo.

Pattern scan · Sunday

Your worst window is every morning.

90% TIROvernight 00–06h
42% TIRMorning 06–12h

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 · photo logging

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/dLMidday meals at 3h
−95 mg/dLEvening 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 at midday meals and −95 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.

Built for patients.
Useful for endocrinologists.
