## What is Polso?

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.

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

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 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.

## Version history (last 5 releases)

### 3.3 — 2026-10-21

A new Polso experience, designed for iPhone Duo.

• Open your Duo to see recovery and sleep, vitals and movement, in thoughtfully paired modules.
• Read your morning brief beside your action list. Open the complete brief in a comfortable reading column.
• Partially fold your device and Polso keeps its main content and input clear of the fold.
• Close your Duo for a compact recovery view and a simpler Coach input bar.
• Refined Trends, Settings, larger text and rotation behavior.

More room for your health. More care in every detail.

### 3.2 — 2026-10-20

The full brief is now a continuous daily recovery report, with expanded analysis of recovery, sleep, body signals, activity load and personal patterns. Explanations sit alongside their charts. Integrated analysis considers current load, reported feelings and the schedule you share, while distinguishing morning recovery from current readiness. Confirm a daily plan and compare it with your evening and next-day records. Body alerts, workout reviews and fitness age add context to short-term changes and longer-term trends. We also fixed overly shortened report repairs and inaccurate wording for unknown HRV sample counts.

### 3.1 — 2026-10-15

Recovery and sleep scores are recalibrated. Sleep now counts for 40% of recovery, so a good night shows clearly in your score. HRV follows your 7-day trend, so normal night-to-night swings no longer pull the score down; fatigue is flagged only when HRV falls while heart rate rises. RMSSD from newer Apple Watch models joins the score after four weeks of data. The sleep score now uses duration, bedtime and interruptions, the same structure as Apple Watch, and going to bed early with enough sleep no longer counts as irregular. AI Coach explains how many points each factor added or removed, says when a night has too few HRV readings to rely on, and records how you say you feel to calibrate future scores.

### 3.0 — 2026-10-14

A new Today: your readiness is now a breathing orb of light with today's percentage at its centre. Sleep, live vitals and activity each get one card that fits on a screen, with the full reading one tap away. The layout is more open, with titles outside the cards and refined spacing and type. AI Coach now gathers your daily plan, yesterday's follow-up and tips, with today's in-depth review first. Trends folds the five long-term dimensions into one "Long-term changes" module. New: a knowledge-only coach mode and two sleep goal modes. Subscription prices are lower, and new users can preview coach readings in the app for 14 days with no subscription and no automatic charge. Adds optional anonymous usage counts that contain no identity, device identifier or health data.

### 2.11 — 2026-10-05

A clearer view of recovery and sleep: consistent modules, subtle colors for health metrics and a gentle breathing effect around your recovery score. More consistent spacing makes settings easier to scan. Recovery and sleep details explain the factors behind your scores, with more reliable validation and retries for AI deep dives.
