"Am I actually healthy?"
Open the app, glance, understand. Two minutes every morning.
One number from 0–100, built from all your Apple Watch data across 7 categories. Adapts to your personal baselines, not population averages. Open the app — instantly know where you stand.
Laso flags when multiple metrics shift together — like HRV dropping while resting heart rate rises. Catches patterns weeks before you'd notice them yourself.
Track how your health changes over weeks, months, and years. Year-over-year comparisons, seasonal patterns, baseline drift — all compared against your own data, not generic benchmarks.
Laso reads from any device that syncs to Apple Health. Wear what you want — we'll read the data.

Heart rate, steps & basics
Any device that writes to Apple Health works with Laso. Sync via companion app — Laso handles the rest.
Not a generic formula. It learns your baselines and adapts to your body — so you see what matters for you.
Sample data — your score is calculated from your own metrics
Not just charts. Laso runs correlation analysis, anomaly detection, pattern recognition, and trend tracking across all your metrics simultaneously.
Finds real connections between 35+ metric pairs. Like how your sleep quality affects next-day resting heart rate.
Flags when a metric goes outside your personal normal. Not population averages — your own baseline.
Measures how fast your HRV bounces back after stress or workouts. Detects overtraining before you feel it.
Tracks consistency, calorie efficiency, and how your cardio fitness responds over time. See if your training is actually working.
Shows exactly how last night's sleep affected today's energy, activity, and heart rate. Data, not guesswork.
Identifies your weakest day, weekend vs. weekday gaps, and consistency patterns you'd never spot yourself.
Catches gradual shifts over 30+ days that happen so slowly you'd miss them. Like your resting heart rate creeping up week by week.
Tracks your bests, longest streaks, and milestones across every metric. Know when you're beating your own records.
Year-over-year comparisons, seasonal norms, all-time percentiles, and long-term trajectory — your health story over months and years.
Here's the kind of thing Laso tells you every morning — things you'd never figure out from Apple Health alone.
"Your resting heart rate has been creeping up for 3 weeks — up 4 bpm from your baseline."
Baseline Drift Detection
"On nights you sleep under 6 hours, your next-day active energy drops 23% on average."
Sleep-Performance Correlation
"Your HRV recovered in 2 days after Monday's workout, down from 4 days last month. You're getting fitter."
Recovery Analysis
"Wednesday is consistently your worst day for step count and sleep quality. Every week for 8 weeks."
Weekly Pattern Analysis
"3 metrics in your Heart category declined this week: resting HR, HRV, and heart rate variability during sleep."
