RECOVERY

How ready is your body today?

A daily 0–100% score built from your Heart Rate Variability and Resting Heart Rate, compared against your personal 60-day baseline. HRV is weighted slightly higher for its strong link to your autonomic nervous system — HRV above your own baseline signals better resilience to stress, physical and mental.

Your Recovery is set once each morning — a clean snapshot of readiness at the start of your day.

EXERTION & TARGET ZONE

Know exactly how hard to push.

Exertion measures your cardiovascular load on a 0–10 scale, accumulating whenever your heart rate rises above a threshold personalized to you.

Your Target Exertion Zone pairs that with today's Recovery and your Training Goal — a personalized range that tells you when to keep pushing and when you've done enough.

SLEEP

Not just how long — how well.

Sleep Quality goes beyond duration: restorative REM and Deep sleep, awake time, interruptions, and respiratory rate all feed one percentage score that tells you how effective your night really was.

Athlytic also tracks Sleep Debt, Sleep Consistency, and your Heart Rate Dip during sleep — the long-term patterns that shape how you feel.

JOURNAL

See what actually moves your numbers.

Log the things that might affect tomorrow — alcohol, late meals, travel, stress — and Impact Analysis shows you how each one actually shifts your Recovery and Sleep over time.

Auto-tags capture naps, sunlight, low stress, menstrual flow, and more with zero effort.

24/7 HEALTH MONITORING

Catch the signal before the symptom.

HRV, Resting Heart Rate, Blood Oxygen, Respiratory Rate, and Wrist Temperature — each tracked against your personal normal range, so an abnormal reading stands out immediately.

Customizable notifications alert you the moment something drifts out of range.

BATTERY

Your readiness, in real time.

While Recovery is set once each morning, Battery updates all day with every new HRV sample — charging with a nap, yoga, or genuine rest, draining after a hard workout or a drink.

Woke up in the red but rested all day? Battery shows when your body is charged enough for that evening session.

STRESS

See what's weighing on you.

Athlytic reads your heart-rate patterns around the clock to chart stress from low to high — and separates real strain from ordinary physical activity.

Watch how sleep, workouts, and daily life move your curve, and catch the days your body needs to downshift.

CYCLE PHASE

Guidance that follows your cycle.

Athlytic tracks your cycle phase alongside Recovery and health metrics, so insights account for the natural shifts in your baseline across the month.

The Journal auto-tags menstrual flow, and training focus adapts to each phase.

WORKOUT TRACKING

Live on your wrist. Deeper on your phone.

During a workout, the Watch app shows your color-coded heart-rate zone, live Effort score, and aerobic vs anaerobic split in real time.

Afterwards, the Workouts tab digs deeper: Cardio Fitness, Heart Rate Recovery, Training Effect on HRV, and coaching that compares your Effort to your own records.
