See your stress in color using real-time heart rate biofeedback. Rewire makes changes in heart rate visible as a simple color display, helping you notice how everyday experiences influence your body and nervous system in real time. By making these patterns visible, Rewire helps users explore mindfulness and stress awareness using real-time physiological feedback. Your nervous system constantly adjusts heart rate as you interact with the world, often before you consciously notice these changes. Rewire helps make these patterns visible so you can observe how your nervous system responds during everyday experiences. Heartbeat Color Visualization Rewire includes a built-in Heartbeat tool that displays heart rate changes using a 7-color visualization similar to a mood ring. Warmer colors show activation while cooler colors reflect states of rest and recovery. As heart rate shifts, the colors change in real time, making patterns easy to recognize. Personalized Baseline Rewire begins by measuring a short baseline reading of your resting heart rate. This baseline is saved so color feedback reflects changes relative to your resting state using seven levels—three above and three below baseline. Privacy-First Design Rewire is designed with a privacy-first approach. Your heart rate data stays on your device and the app does not require accounts, passwords, or subscriptions. Optional Dome Light Display Rewire also works with the Rewire Dome Biofeedback System—a 7-color light display that mirrors the Heartbeat tool colors in real time. The Rewire Dome Biofeedback Kit is sold separately at rewirestress.com. Who This App Is For Rewire is designed for people who want to: • learn how their body responds to stress • observe how the nervous system responds during everyday experiences • practice mindfulness using real-time biofeedback • explore ways to calm the body in everyday situations • recognize patterns in physiological responses Guided Practice Rewire includes sensory media channels that guide users through simple techniques designed to support calming and focus. These practices allow users to observe how breathing, attention, and sensory input influence heart rate in real time. Purpose Rewire is a behavioral biofeedback training tool designed to support awareness of stress responses, nervous system education, and mindfulness practice through real-time physiological feedback. Rewire does not diagnose, treat, or modify medical conditions. How It Works Rewire requires a compatible Bluetooth heart rate monitor to measure heart rate and provide real-time color feedback. • Open the built-in Heartbeat tool • Connect a compatible Bluetooth heart rate monitor • Measure your resting heart rate baseline (about 90 seconds) • Press Play to begin the color visualization • Colors respond to changes relative to your baseline • If using the Rewire Dome, the device mirrors the same colors in real time Compatibility Rewire requires a Bluetooth Low Energy (BLE) heart rate monitor that broadcasts live heart rate data. Some Garmin devices allow heart rate broadcasting when manually enabled. Apple Watch and Fitbit devices do not currently broadcast live heart rate data to third-party apps in this format. ## Key features - Real-time heart rate biofeedback - Color visualization of stress levels - Personalized resting heart rate baseline - Privacy-first design, data stays on device - Guided mindfulness and calming practices - Optional integration with Rewire Dome display ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/rewire-heart-rate-biofeedback/id1460843569/reviews.md ### 5/5 — It changes your life! *2020-06-16* If I tried to put into words how amazing this app is I would fail you just have to use it and you will feel the difference in your life ## Frequently asked questions about Rewire ### What is Rewire's primary function?
