You wake up and check your step count, your sleep duration, your resting heart rate. Three numbers from three sources that you mentally combine into a vague sense of "I feel okay today." The Energy Score replaces that guesswork with a single composite metric.
Five Factors, One Score
The Energy Score combines five weighted factors into a 0-100 composite:
- Sleep (25%) — 7-9 hours is optimal (score: 100). Under 5 or over 11 scores poorly. The sweet spot is not just "more sleep" — it is the right amount.
- Activity (25%) — Steps toward a 10,000 daily target. Hitting the target scores 100. Diminishing returns above it.
- Heart Rate (15%) — Resting heart rate between 50-60 BPM is optimal. Higher resting HR suggests stress or poor recovery.
- Focus (20%) — Productive app time as a percentage of total screen time. Higher focus ratio means better energy allocation.
- Balance (15%) — Total screen time between 6-12 hours is optimal. Under 6 means the tracker is not capturing your day. Over 12 means you are overworking.
Smart Weight Redistribution
Not everyone has all five data sources connected. If you do not have HealthKit syncing heart rate, that 15% weight gets redistributed proportionally across the factors you do have. The score stays meaningful even with partial data — you just get a coarser signal.
The Energy Dashboard
The Energy page shows your score prominently with a breakdown by factor. Below that, three visualizations:
- 7-day trend — a line chart showing your Energy Score over the past week, so you can spot patterns (maybe Mondays are always low)
- 30-day history — the longer view for identifying sustained trends
- Contextual insights — auto-generated text comparing today to your 7-day average, flagging which factor is dragging the score down, and detecting upward or downward trends
How to Use It
The Energy Score is not a prescription. It is a decision input. Score above 80? Good day to tackle that complex refactor. Score below 50? Maybe focus on code reviews and documentation instead of deep work. The score gives you permission to adjust your ambition to your actual capacity.
The most useful pattern is tracking the score against your output over time. After a few weeks, you will know your personal threshold — the score below which deep work is a losing bet. That self-knowledge is worth more than any productivity hack.
