Find your pace. Explore your heart's response.

Sympathetic brings guided breathing and personal physiology together on your iPhone. Follow a visual breathing guide with optional sound and haptic cues, choose a comfortable pace, and build a regular practice.

BREATHE AT YOUR PACE
Guided breathing is free and works without a chest strap. Choose your breathing rate, inhale/exhale balance and session length. Use Focus mode to keep the guide in view.

EXPLORE WITH POLAR H10
A Sympathetic H10 subscription unlocks Polar H10 connections, heart-rate and HRV feedback, breathing assessments, adaptive feedback and ECG recording. Review your response during training, browse saved waveforms and export recordings for your own analysis. A Polar H10 is required for these features and is sold separately.

SUBSCRIPTION OPTIONS
Choose an annual or monthly plan. The annual plan offers a lower cost than twelve monthly payments. Eligible new subscribers receive a two-week free trial, followed by automatic renewal at the price shown when subscribing unless cancelled. Manage or cancel your subscription in your Apple Account settings. Restore Purchases is available in the app. Previously saved records remain readable and exportable after a subscription ends.

KEEP YOUR PRACTICE PRIVATE
Your recordings and analysis stay on your iPhone unless you choose to export them. No app account, advertising or analytics. Apple processes subscription purchases. Optionally save confirmed breathing time to Apple Health as Mindful Minutes.

Sympathetic is an independent app and is not affiliated with Polar. It is for personal exploration and general wellness. Its scores, breathing estimates, ECG observations and single-lead measurements are experimental and are not intended for diagnosis, treatment or medical decisions.
