Polso: HRV & Sleep Score

Understand your Apple Watch HRV, sleep and recovery trends against your own baseline. Polso brings available health data together with optional AI coaching.

REDESIGNED FOR IPHONE DUO
Open your Duo to see recovery and sleep, vitals and movement, in carefully aligned modules. Read your morning brief beside your action list. When partially folded, content and input avoid the system fold region. Close your Duo for a clear, compact outer-display view. Refined reading widths, larger text and rotation make room for your health.

YOUR COMPLETE DAILY REPORT — PRO
Read recovery, sleep, body signals, activity load and personal patterns with supporting charts. Discuss adjustments using the schedule and feelings you share. Confirm your daily arrangement and revisit it with evening and next-day records. Body-signal alerts, workout reviews and fitness-age estimates use available personal data and acknowledge its limits.

Why did your HRV drop? You slept well, so how should you train today? Polso connects Apple Watch HRV (heart rate variability), heart rate, sleep and activity data with a conversational AI coach. Once you authorize Health access, you do not have to copy your readings into every question. The coach can retrieve relevant data and combine it with your goals, personal notes and recent conversation.

HRV AND RECOVERY, IN CONTEXT
Compare daytime and nighttime HRV against separate personal baselines. Robust summaries reduce the influence of occasional extreme readings. See your typical range, sample times, sample counts and baseline maturity. Distinguish recent changes from your longer-term pattern, with heart rate, sleep and activity providing context. Limited data means more cautious estimates.

A CONTINUOUS AI COACH — PRO
Ask about fitness, strength training, sleep, recovery and post-workout nutrition. Add “I only have 20 minutes” or “I only have dumbbells” and refine the plan in the same conversation. General questions can draw on broader knowledge; personal interpretations use available evidence and acknowledge missing data.

CONSISTENT SLEEP INSIGHTS
Understand duration, continuity, timing and sleep stages. Nightly scores and explanations share a personal baseline; tonight's extra sleep target guides your plan without becoming another penalty for last night.

YOUR CONTEXT MATTERS
Record alcohol, caffeine, stress, discomfort and how you feel on a dedicated page. Update whether an event still affects you. These reports help explain your state and adapt advice. Uncompleted suggestions do not lower readiness. Explore HRV, heart rate, sleep and training trends across weeks, months and years.

FREE AND PRO
Readiness, charts, basic insights and personal context records are free. Polso Pro unlocks the continuous AI coach, detailed reports and long-term insights.

Requires Apple Watch and permission to read Apple Health data. Estimates update as new data syncs; Watch sampling and Health synchronization are not a continuous live feed. The readiness percentage is a model estimate, not a measured percentage of energy remaining.

Recovery calculations run on your iPhone. Only with your explicit consent do AI features send relevant health summaries and your inputs through Cloudflare to OpenAI. You can decline or withdraw consent. No account, no ads, no data sales.

Polso provides fitness and recovery guidance, not medical diagnosis, treatment or prevention.
