Audio Heart Rate: HR Intervals

Train by heart rate without a watch and without looking at your phone. Audio HR connects to your Bluetooth heart rate chest strap or HR monitor watch, tracks your beats per minute in real time, announces them and tells you out loud when to push, when to ease off, and when the next interval starts. Put the phone in your pocket, and concentrate on the workout. SINGLE in app purchase supports development, removes ads and unlocks theme, voice and sound customization. There will NEVER be a subscription. Three ways to train (All fully customizable) - Pacer: pick a heart rate zone and stay in it. Spoken alerts tell you when you drift above or below the zone, and a chime confirms when you are back on target. - Simple Intervals: work and rest periods on a timer, with your heart rate announced during each phase. Classic HIIT with heart rate indicators of success. - Complex Intervals: build a full session from timed phases, heart-rate-driven phases that only end when you reach (or avoid) a target, loops, and warm-ups. Ready-made sessions include 10-20-30 Intervals, Pyramid Fartlek, Descending Ladder, Hill Repeat Sim, Threshold Sandwich, Maffetone plus Surges, and a Bike 250 kcal Challenge, and every one of them can be copied and edited. Hear your heart rate any way you want - Heart rate spoken at the interval you choose (or not at all if you're just logging), with beeps for phase changes. - Out-of-zone alerts as strict as you decide. Want aggressive coaching? Have it. - Approach warnings before a heart rate target so you know what's coming. - Works with the screen off and keeps running during calls and other apps, because why are these people bothering you anyway? Track yourself and log your progress - Every workout is saved with a heart rate graph, time in each phase, top and average heart rate, and calories. - Calories use your age, sex, weight and height, with a resting metabolic rate you can override and an optional resting heart rate correction. - Max heart rate is estimated from your age or set to your own tested value. - Export any session, or all of them, as CSV for a spreadsheet or your coach. Make it yours - Extremely customizable Complex Intervals mode functions with and without a strap and is a full-fledged interval timer app all by itself. - Dark, light and colored themes, with adjustable text, button and accent colors. - An interval-only timer mode for days when you train without a strap. - Big-display mode for the phone on a treadmill console or bike stem. - Premium allows for any installed TTS voice to be chosen. Want to be yelled at in French? Anything is possible. Premium, a single one-time purchase, adds custom announcement phrases, voices and sounds, a theme maker for your own colors, and removes ads. Everything else stays available with ads. What you need (The app can't tell your heart rate all by itself) - A Bluetooth Low Energy heart rate chest strap or sports watch that broadcasts the standard Heart Rate Service. Most straps from Polar, Garmin, Wahoo, Coospo and similar brands do, as do many watches with a broadcast mode. - Android 8.0 or later. The app does not create accounts and does not send your heart rate or profile anywhere. Sessions stay on your phone unless you export them.
