Polso: HRV & AI Recovery Coach

Make more of your Apple Watch: personal HRV ranges, separate day and night baselines, and an AI coach that helps you plan recovery and training.

Turn the Apple Watch you already own into a recovery coach that understands you.

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. Eligible users can try Pro free for 7 days.

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 DeepSeek. 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.
