Local-first personal health analytics platform. Bynálix is designed for long-term self-observation, not engagement optimization. Track, observe, and analyze your own long-term behavioral data — without relying on opaque cloud AI systems.
Bynálix is not designed to tell users how to live.
Instead, it helps users:
- Record long-term personal data
- Observe behavioral patterns
- Explore correlations
- Understand what actually affects them
The goal is not blind optimization, but deeper personal understanding through self-owned data.
- Local-first architecture
- SQLite-based structured data storage
- Nutrition tracking (foods, meals, reusable meal templates)
- Workout tracking — strength training (sets & reps) and interval-based cardio
- Body composition tracking (body fat, segmental muscle, body water, visceral fat, waist)
- Goal & mode system (weight, calorie, macronutrient, and hydration targets)
- Sleep & hydration tracking
- Historical visualization
- Correlation analysis
- Custom exercises & foods
- App lock — PIN and biometric unlock (Android)
- Encrypted CSV export (password-protected, AES-256)
- Full database export / import for backup & restore
- Offline-first
- Dual-language support (English / Chinese)
- Bug fix — TDEE activity multipliers corrected to Harris-Benedict standard (1.2–1.9×); previously under-estimated by ~10–50%
- Nutrition — fat calorie ratio slider (25–35% of TDEE, default 30%) added to mode settings; macro formula updated: fat = TDEE × ratio, carbs fill remainder
- Bulk rates — conservative weekly gain targets: slow 0.10%, normal 0.15%, aggressive 0.25% body weight
- Body fat — BF% field in Profile locked after initial setup; updates must go through body comp log or weight entry
- BF staleness alerts — app notifies once per threshold (30 / 45 / 75 / 105 / 135 / 165 / 180 days since last BF reading); weight rows show
⚠️ at 30–179 days stale and red tint at 180+ days - Sleep — wake-up time field added; inferred sleep start time calculated from wake time minus duration
- Code quality — empty catch blocks in Statistics replaced with logError
- Code architecture — major internal refactoring: component library (EmptyState, StickyHeader, PillButton, CardHeader, Modal/Dialog/BottomSheet), design token system (spacing, font sizes), and style centralization
- Bug fix — cycling history now correctly includes spinning bike (飛輪) entries
- CI/CD — automated multi-platform release pipeline via GitHub Actions (Windows / macOS / iOS / Android)
- Trend analysis tab — z-score normalized trend chart (weight / sleep / calories) with adaptive slope detection and direction indicators
- Lag analysis — 3 independent lag sections correlating factors against weight change, sleep change, and calorie change
- Reliability improvements — robust z-score (median + MAD), minimum data threshold lowered to 7 days
- Basic stats — correlation ranking bar chart added (matching advanced tab)
- History — cardio chart uses dual Y-axis (duration left, calories right)
- Bug fix — body history drawer transparency resolved
Bynálix was created to help users verify ideas using their own long-term data, instead of relying entirely on generalized internet advice.
Correlation does not imply causation. Bynálix provides exploratory analytics designed to help users observe potential behavioral patterns over time.
