Features
Orbit tracks eight metrics from your wearable data and your own logging: Recovery, Strain, Sleep, muscle recovery, Training, Nutrition, Habits & journal, and an AI Coach that reads across all of them.
Recovery
A daily score reflecting how ready your body is to train, shown as a color-banded ring.
[TODO: the exact inputs and thresholds behind the Recovery score.]

Strain
A daily score reflecting how much load your body has taken on, shown alongside Recovery and Sleep.
[TODO: the exact inputs and thresholds behind the Strain score.]

Sleep
A daily score reflecting last night's sleep, shown as a color-banded ring alongside Recovery and Strain.
[TODO: the exact inputs and thresholds behind the Sleep score.]

Muscle recovery
An interactive front-and-back body map covering 19 independently tracked muscle groups. Tap any one for its recovery percentage, last-trained time, estimated hours remaining, and the sessions that got it there.
[TODO: the exact formula converting logged sets and activities into a per-muscle recovery percentage.]

Training
Log weight, reps, and RIR per set from a roughly 150-exercise catalog, and Orbit's progression engine prescribes your next session with the reasoning behind it.
[TODO: the exact e1RM and auto-progression formula.]

Nutrition
Editable weekly diet-plan days, a macro row for calories, protein, carbs, and fat, your TDEE computed from your profile, and a free-form log for anything that doesn't fit the plan.
[TODO: the exact TDEE calculation and the data points it's derived from.]

Habits & journal
Habit tracking with streak badges and completion rates, plus a daily one-question-at-a-time journal drawn from about 144 questions across 9 categories.
[TODO: the exact method correlating journal answers and habits against next-morning Recovery.]
AI Coach
Ask about your training, meals, habits, or recovery trend. The Coach answers using tools that read your real numbers, and proposes a draft workout or diet day you can Apply or Discard — nothing changes without your approval.
Not a medical assistant — Orbit's Coach doesn't diagnose, treat, or detect anything.
