Flamingo Readiness. A simpler way to understand trends in your health data and improve your recovery process. Flamingo is a health and wellness app that integrates with HealthKit data to track metrics specific to your unique heart rate and sleep schedule. Using data automatically captured from the Health app by your Apple Watch device, Flamingo generates a personal readiness score every day that can help you stay informed about your mental and physical state of readiness. Readiness is calculated daily by measuring 3 health metrics: Heart Rate, Heart Rate Variability, and Sleep. Your data is never compared to an absolute scale - after all, everyone is different. Instead, each metric is compared against your average value to determine positive or negative trends that may indicate a need for rest and recovery. The greater these trends are, the more they impact your readiness score. Just wear your Apple Watch to sleep, then check Flamingo first thing when you wake up for best results. Charts are designed to be simple to understand and reconfigurable so that you don't have to sift through complicated details and rows of data. Visualize trends for individual metrics, or access historical data to understand how your readiness has changed over time and how it has been impacted by each metric. Flamingo is free to download for a limited time to gather feedback and improve the experience as much as possible. Please share any feedback you have with flamingo@toggle.llc This app was developed with SwiftUI. The information provided in this app is for informational purposes only. Flamingo is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Always take into account how you feel to assess readiness and consult with a medical professional if you have any questions about your health.

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
