ROADMAP

Where this is going.

Phase 1 is the core loop. Once that's solid, Phase 2 brings in CGM data and starts learning from what's actually happening after meals. Phase 3 is the native app and the features that depend on having enough history to be useful.

LIVEPHASE 1

The core loop

Photo and voice capture, carb estimation, insulin ratio math, meal log. The basics, done properly.

Photo carb estimation via AI (Claude vision)
Voice capture: describe what you're ordering before it arrives
IC ratio-based insulin recommendation
Confidence score on every estimate
Human confirmation before any dose is logged
Parent authorisation for teenagers: parents can approve account setup for under-18s
Full meal log with timestamps
Starter and Plus subscription tiers
Dark theme
Google login integration
Beta test programme
Time-of-day IC ratios: set different ratios for morning, afternoon, and evening to account for insulin resistance patterns
Offline-first voice queuing
Native iOS and Android apps
NZ and AU food database improvements (local foods, takeaway chains)
Health New Zealand | Te Whatu Ora partnership: working with NZ's national health system toward formal recognition of Carbol within T1D care
UP NEXTPHASE 2

CGM integration + pattern analysis

This is where it gets more useful. I want to see your glucose before recommending a dose, and I want to learn from what's actually happening after meals.

LibreLink and Dexcom CGM integration: see current glucose before dosing
Post-meal BG tracking: did the estimate hold?
Pattern analysis: which foods consistently spike you?
IC ratio drift detection: flag when your ratio seems off
Pre-bolus timing recommendations based on your personal data
Export meal + BG data as CSV for your endo
Better starting point estimates calibrated to your meal history
LATERPHASE 3

Native app + advanced features

A proper iOS and Android app, family accounts, and the features that need Phase 2 data to work properly.

Native iOS and Android app
Pre-bolus timing reminders
Apple Watch and WearOS complications (current BG at a glance)
Family accounts: parents managing T1D kids
Endo sharing: send a report directly to your healthcare team
Correction dose calculator (current BG + sensitivity factor)
Meal tagging and custom entries for foods you eat regularly

Timelines aren't published because I work on this around a day job and a T1D life. Phase 2 starts when Phase 1 is stable. If something's important to you, tell me.
