Yudemon HRV is a unique visual and sonic tool for resonance breathing and HRV biofeedback training. It provides a fun and engaging workout for your autonomic nervous system, helping you build stress resilience and enhanced self-regulation. You can either use the app as a basic breath timer, or connect an ECG-based heart rate monitor (like the Polar H10) via Bluetooth for full biofeedback and analytics. Unless you specifically opt-in to cloud sync, all data processing happens on your device, so your data is completely secure. Using Yudemon with a heart rate monitor not only allows you to track and visualise your data for each session, it also enables you to use Yudemon's Journey Mode, a novel and unique way of establishing your own optimal breathing rate over the course of multiple sessions. Yudemon's adjustable visuals and soundscapes offer infinite variations, making every breathing session feel fresh and engaging. By default, the app’s appearance automatically changes on a daily basis. Or, with Yudemon Pro, you can take full control and customize everything manually. A healthy heart does not beat like a metronome but constantly adapts to the requirements of the present moment. Heart rate variability (HRV) biofeedback training and resonance breathing are based on the fact that our breathing has a direct impact on the rest of our physiology. By controlling our breathing in specific ways we can train our body to become more adaptable and perform better under stress. Yudemon helps you with this practice. Yudemon HRV is the first breathing app with custom soundsapes and functional music specifically designed for resonance breathing and HRV biofeedback training. The soundscapes guide you in your breathing sessions and aim to enhance the effects of the practice. It also integrates other aspects of generative art, such as the "Heartwork", a unique piece of art based on your very own physiological data that is generated and grows with you as you complete more sessions. New visuals, soundscapes, and effects are added on a regular basis. Terms of Service: https://app.yudemon.com/terms Privacy Policy: https://app.yudemon.com/privacy

Your recovery. A clearer picture. See how your body responds, day after day. Trendwell brings your Apple Watch data together in clear daily and weekly reports, helping you understand your recovery trends, spot patterns, and see the bigger picture. Follow changes in your heart rate, HRV, sleep, and activity. Return to a familiar walk, hike, run, or ride and discover how your response compares. —— START WITH A DATE THAT MATTERS Your recovery has a starting point. Choose your Recovery Start Date and explore the Apple Health data already recorded from that day onwards. Build a timeline that means something to you. —— MAKE SENSE OF TODAY Open your daily report for a clear view of how your body is responding — stable, variable, or shifted — and the signals behind it. Explore activity load, sleep, recovery indicators, and trend direction together. See system stability across recorded sessions and understand how today's data fits into your wider picture. —— FIND THE PATTERN ACROSS YOUR WEEK Step back and see how the days fit together. Weekly reports bring state consistency, heart rate, HRV, and recovery load trends into one structured view. Keep the habit with an optional weekly reminder. Choose the day and time that work for you. —— SAME ROUTE. A FRESH PERSPECTIVE. Make a familiar route your point of comparison. Find a previous walk, hike, run, or ride by activity type and date, then follow its saved track again. See progress and upcoming turns in the app or Live Activity, with optional haptics and continuation while your screen is locked. Afterward, compare matched sections across pace, moving time, elapsed time, heart rate, elevation, and climbs. Route-match and data-quality details put each comparison in context. Route following retraces your recorded GPS track. Export a previous route as GPX to use in another suitable app. —— PUT EVERY CLIMB IN CONTEXT Every climb adds context. See your heart rate alongside the elevation you actually climbed, and explore how your response varies across the terrain of your route. —— YOUR TRENDS, READY TO SHARE Bring your history together in a Follow-Up Report: a multi-page PDF covering load, resting heart rate, HRV, system stability, and efficiency trends across your full reporting window. Keep a personal record. Share the bigger picture. Revisit your trends as your timeline grows. —— YOUR DATA. ON YOUR IPHONE. Reports are generated entirely on your device. Your health data stays on your iPhone, and you choose whether to export or share a report. Every conclusion comes from a consistent, rule-based system and is traceable to the data behind it. Generation time varies by device model. —— GET MORE FROM YOUR APPLE WATCH Apple Watch is recommended for complete reports, including HRV, sleep, and route data. Consistent wear, including during sleep, gives Trendwell more data to work with; 23+ hours daily is recommended for coverage. Trendwell reads your data automatically from Apple Health. Other Apple Health sources provide partial coverage. —— START WITH A 7-DAY FREE TRIAL Explore Trendwell with a monthly subscription and a 7-day free trial. Or choose Trendwell Forever: one payment for permanent access. Auto-renewable subscriptions renew unless cancelled at least 24 hours before the end of the current period.
