Listen To Your Heart

Set a target heart-rate zone. Inside it you hear nothing at all - your music or podcast plays normally. Drift out of it and the audio ducks under a chime whose rhythm tells you how far off you are, and which way, without looking at anything. HOW IT SOUNDS - Direction is pitch: bright high pips mean you are above your zone, low dark pips mean below. - Distance is rhythm: the further out you are, the more pips in the group and the faster it repeats, from one slow pip every four seconds just outside the zone to four fast pips when you are far out. - Nothing ever gets louder. The alert ducks your audio briefly and your podcast or playlist comes straight back. WHERE IT PLAYS Tap Start on your iPhone and it keeps sounding the alert with the screen off and the phone in your pocket, for as long as your workout lasts, until you tap Stop. Or tap Start on your Apple Watch instead and it plays there - on its speaker, or on AirPods connected to the watch. Start a session on the phone and the watch stays quiet, so you never hear both. Start your workout in any app you like - Workout, Strava, Nike Run Club - Listen To Your Heart takes no workout of its own, so theirs keeps running. PRIVATE BY DESIGN Your heart rate never leaves your devices. No accounts, no ads, no tracking. HealthKit is read-only, used live during your session and never stored by the app. The iPhone app sends anonymous usage analytics to the developer's own server - which screen opened and the steps of the subscription flow - that never contain health data and are not linked to you. Listen To Your Heart is a fitness pacing aid, not a medical device. It does not diagnose, treat, or monitor any medical condition. Requires an Apple Watch to measure your heart rate. Set your zone and start the session on either device. SUBSCRIPTION Listen To Your Heart - $4.99 per month, with your first month free.
