Upavāsa: Intelligent Circadian Fasting
Where rigorous cellular biology harmonizes with ancient Ayurvedic wisdom. Synchronize autophagy, ketosis, and growth hormone resets with personal dosha balance, Agni digestive fire, and lunar rhythms.
Scientific Precision
Real-time biological stage tracking across 6 metabolic zones: blood sugar balance, glycogen depletion, fat oxidation, ketosis kinetics, and cellular autophagy.
Yogic Intelligence
Agni digestive fire index, Pancha Kosha alignment, and a 9-axis Yogic Alignment Wheel computed dynamically from real adherence and sleep telemetry.
Adhikara Safety Gate
Hardcoded medical protection. Automatic screening for BMI < 18.5, pregnancy, eating disorder history, and a strict 14h soft-cap for hypoglycemia/diabetes.
Adaptive Periodization
Multi-week challenge plans with demonstrated headroom throttling, protecting beginner users from over-fasting while pacing advanced practitioners.
Live Fasting Tracker & Tri-Ring Telemetry
Concentric spatial architecture with an Inner Ring tracking elapsed target duration, Middle Ring logging chronological hydration, mood, and weight beads, and Outer Ring mapping 24-hour solar circadian cycles, sleep arcs, and timed Sadhana recommendations with dynamic 6-stage biological color morphing.
Advance Charting
Six clinical-grade visualizations on the History screen: Interactive Fasting Duration Bar Charts with touch scrubbing, 24h Circadian Clock Wheels, 9-Axis Radial Yogic Alignment Spider Wheels, Trailing 30-Day Moving Average Weight/Lean Curves, Metabolic Zone Mix Charts, and Consistency Calendar Grids.
Data Management & Sovereignty
Zero proprietary lock-in. Seamless CSV/JSON import engine supporting 9 competitor apps (Zero, Life, Fastic, Simple, BodyFast, FastHabit, DoFasting, Window, MyFitnessPal) with staged duplicate detection, paired with one-tap full JSON data export for complete user data sovereignty.
Dual-Lingual Architecture
Fully native bilingual platform with end-to-end support for both English and Spanish (Español) across every screen, biological metabolic stage telemetry, Ayurvedic aphorisms, clinical surveys, Dinacharya guidance, and system notifications with instant in-app locale switching.
Semantic Similarity Search
Offline-first vector intelligence powered by PostgreSQL pgvector embeddings across 35+ verified fasting research papers, classical Ayurvedic treatises, and scriptural knowledge chunks for instant citation retrieval with zero third-party cloud LLM data leaks.
Voice Enabled
Hands-free biometric logging powered by our native Voice Service (VoiceRecorderService & /voice/transcribe API): effortlessly record voice check-ins, journal reflections, and sensation logs with real-time transcription and automatic field extraction without manual typing.
Interactive Circadian Metabolic Dial
Drag the interactive slider to visualize your physiological transitions—from initial digestive pause to deep cellular recycling and immune rejuvenation.
Autophagy Induction & Cellular Recycling
Cellular self-cleaning (autophagy) initiates. Lysosomes locate damaged mitochondria, misfolded proteins, and intracellular pathogens, breaking them down into pristine amino acids.
"Tapas (Purifying Fire): Deep metabolic heat cleanses mental fatigue and promotes inner stillness, as voluntary restraint fortifies the spirit."
Live Fasting Tracker & Tri-Ring Telemetry
Inspired by the native Upavāsa mobile screen (fasting_tracker_screen.dart). On the left, interact with the live tri-ring timer with real-time countdown, quick-log action badges, and dynamic hourly biological color morphing. On the right, explore how our concentric ring architecture bridges cellular stages, hydration telemetry, and weight kinetics.
Tri-Ring Architecture
Concentric spatial hierarchy designed for complete biological clarity. The Inner Ring tracks active elapsed duration toward your protocol target; the Middle Ring marks chronological hydration, mood, and weight log beads; and the Outer Ring maps your 24-hour solar circadian day and sleep cycle.
Adaptive Biological Colors
Upavāsa abandons static progress bars. The timer ring dynamically shifts its glow across 6 biological hues based on real metabolic shifts: Muted Ochre (0–4h Fed) → Muted Olive (4–12h Glycogen) → Muted Ochre (12–16h Fat Burn) → Muted Terracotta (16–24h Ketosis) → Muted Red (24–36h Autophagy) → Deep Blue (36h+ Renewal).
Progress & Vitality Check-Ins
Log momentary hunger waves, energy vitality, and mood on a standardized 1–5 scale directly from the active tracker. Upavāsa detects transient ghrelin spikes and immediately recommends 3-minute Nadi Shodhana breathwork pauses to calm autonomic sympathetic drive.
Hydration & Ushapan Telemetry
Continuous fluid tracking with millilitre and ounce precision. Distinguishes between Ayurvedic morning Ushapan (warm copper water), soothing herbal infusions (Tulsi, ginger), and mineral spring water with pink salt electrolytes to prevent headache or cramps.
Weight & Lean Mass Tracking
Morning baseline weigh-in logging integrated with a rolling 7-day smoothed average. Upavāsa monitors your rate of loss against the safe 1.5–2.0 lbs/week ceiling to ensure that fat is mobilized while vital lean musculoskeletal tissue remains fully shielded.
Dynamic Window Adjustment
Life happens. Seamlessly adjust your start or target goal time directly on the screen without resetting session telemetry. Built-in Adhikara validation ensures the window cannot be edited forward past elapsed time or expanded beyond safe biological bounds.
Adaptive Fasting Challenge Plan
On the left, interact directly with the active 4-Week Fasting Challenge plan inside our native mobile interface (rendered in dark mode with full vertical scrolling and 7 wizard steps). On the right, explore how our periodization algorithms dynamically construct, pace, and protect the plan.
Dynamic Periodization vs. Static Checklists
Unlike static calorie apps with repetitive checklists, Upavāsa's periodization engine treats fasting as a progressive athletic and energetic discipline. Daily fasting windows wave dynamically between gentle 14:10 recovery days, 16:8 baseline rhythms, and crescendo 18:6 autophagy peaks.
Demonstrated Headroom Throttling
We enforce strict safety ceilings. Even if an ambitious beginner requests intensive 36-hour multi-day fasts, the Periodization Engine throttles generation using Demonstrated Headroom logic: no user can unlock a fast >18h without verified prior completion history in the database.
Dinacharya & Sacred Rest-Day Protection
Rest days are non-negotiable metabolic guardrails. On user-selected rest days, the engine prevents fast starts and replaces timer metrics with Ayurvedic Dinacharya restorative routines: warm Abhyanga self-massage, grounding diet, and nervous system recovery.
Seamless Native Calendar Export (.ics)
Your fasting commitment lives in your real-world workflow. Upavāsa automatically generates RFC 5545 standard .ics calendar exports containing all scheduled fasting start times, target goal completions, and Ayurvedic Dinacharya practice alerts.
Dosha-Calibrated Window Escalation
Each constitutional type responds uniquely to digestive pauses: Pitta constitutions require moderate pacing with coconut water to prevent excess heat; Vata types receive warm grounding broth protocols; Kapha types progress safely toward deeper lipolysis.
Auto-Pause Safety Mechanism
If life interrupts your challenge and 3 consecutive fasts are missed, the engine automatically pauses the schedule rather than accumulating failure streaks, offering a compassionate Ayurvedic re-entry protocol upon return.

Day Details
The 9-Principle Yogic Alignment Vector
Upavāsa is the world's only fasting tracker that calculates real, empirical alignment against traditional Vedic lifestyle principles—grounded in your actual fasting logs and wearable recovery metrics.
Strict adherence to conscious eating boundaries. Protects digestive rest periods, prevents late-night insulin spikes, and practices Mitahara (temperate eating).
Cultivation of inner fortitude (Tapas) and bodily purification (Saucha). Measures consistent check-ins, hydration diligence, and sustained daily habit tracking.
Balancing metabolic activity with deep physiological restoration. Fasting reduces nocturnal metabolic workload, allowing extended deep and REM sleep cycles.
Harnessing the cognitive clarity of ketosis. Fasting reduces brain fog, allowing practitioners to sit comfortably in meditative absorption without digestive agitation.
The continuous commitment to self-evolution. Honors Ekadashi lunar fasts and pairs dynamic yoga routines with metabolic phases.
Systemic lightness of being (Laghu). The subjective and somatic balance achieved when cellular autophagy removes metabolic debris and emotional restlessness.
Overcoming psychological cravings and false hunger signals (Ghrelin spikes) through non-attachment and emotional sovereignty.
Sustained intellectual focus driven by elevated BDNF (Brain-Derived Neurotrophic Factor) and steady neuronal ketone fuel.
Synchronizing daily activities with the solar arc: eating when the sun is highest (Surya Nadi active) and fasting through the lunar rest period.
Adhikara Medical Safety Gate
In classical Ayurveda, Adhikara (अधिकार) means 'earned qualification and constitutional readiness'. In Upavāsa, it is our deterministic, non-overridable medical safety engine that screens every protocol against verified clinical boundaries before a timer can ever start.
