DOS BTS
Comprehensive diabetes management with intelligent food logging. Camera-based meal recognition, HealthKit integration, and glucose correlation insights—all in a distinctive amber CGA aesthetic.
The Problem
Managing Type 2 diabetes requires tracking glucose levels, food intake, medication, and activity—data that currently lives in disconnected silos. Your CGM data is in one app, food logs in another, and Apple Health tries to unify it all but lacks the intelligence to show meaningful correlations.
Food logging is particularly tedious. You either scan barcodes (not available for fresh food), search databases (inconsistent results), or manually enter macros (time-consuming). After a meal, the last thing you want is to spend five minutes documenting it.
The result: incomplete data, missed insights, and the nagging feeling that you're not really in control of your health data.
The Solution
DOS BTS consolidates all diabetes-related data into one unified interface. It pulls from your Freestyle Libre 3 via HealthKit, learns your food preferences over time, and uses camera-based recognition to log meals in seconds.
The killer feature: glucose correlation. See how specific foods affect your blood sugar, not just population averages. Over time, the app learns your patterns and suggests adjustments. All data stays on your device—no cloud dependency, complete privacy.
Planned Features
HealthKit Integration
Unified view of glucose, activity, and health data from all sources
Camera Food Logging
Snap a photo, confirm the meal, done. AI-assisted recognition
Glucose Correlation
See how foods affect your personal glucose response
Smart Suggestions
Learn your patterns and suggest meal timing and choices
Privacy-First
All data on device. Optional CloudKit sync across your devices only
Amber CGA Aesthetic
Distinctive DOS terminal design, easy on the eyes
Architecture
Built with a HealthKit-centric architecture. Apple Health serves as the single source of truth for all health data, while Core Data handles local storage and Core ML powers the food recognition.

Planning Milestones
Finished comprehensive documentation: requirements spec, system architecture, design system, and development guidelines. Ready for implementation.
Established the DOS amber CGA aesthetic specifications. Adapted Eidotter tokens for native iOS with SwiftUI-specific implementations.
Designed HealthKit-centric architecture. Core Data for local storage, CloudKit for sync, with complete user data ownership.
Analyzed existing diabetes apps (MySugr, Libre). Identified gaps in data continuity and food logging intelligence.
Started planning after frustration with fragmented diabetes data across multiple apps. Vision: one unified system.
Part of Timeline OS
DOS BTS is a "mod" in the Timeline OS ecosystem focused on health data. Your glucose readings, meals, and health insights flow into your personal timeline, connecting with sleep, activity, and stress patterns to reveal the full picture of your wellbeing.
