Heart Sit vs BeatZone

Did it actually work? The question every meditator secretly asks. Heart Sit answers it. Live heart rate from your AirPods Pro 3 or Apple Watch — captured every second, plotted around your timer, analyzed across weeks. Stop guessing. Start observing. LIVE HEART RATE Choose your sensor: AirPods Pro 3 (in-ear optical), Apple Watch, or Auto. Heart Sit shows which device is providing the reading in real time. No chest strap. No additional hardware. THE OBSERVED INSIGHT Every session ends with a one-line answer: "Your heart rate dropped 8 BPM." Or "Heart rate stayed steady — calm baseline." Compare this week to your 90-day baseline in Trends. Watch the line move. THE SETTLE SCORE Proprietary metric that measures how long it took your heart rate to reach its session minimum. Lower means you settled faster. Track it across weeks. Brag about it. APPLE WATCH AS REMOTE Open Heart Sit on your Watch — it becomes a control surface. Pause, resume, stop from your wrist. The Watch app stays alive for the full session via Extended Runtime Sessions. Your phone can sit screen-down across the room. PRACTICE TYPES Open, Zazen, Vipassana, Breath Focus. Each comes with appropriate defaults. Tag your sessions and see which practice settles you fastest. CONTEXT TAGS + MOOD Tag morning, evening, post-workout, stressed, calm. Capture your mood after each session. Heart Sit will show you which contexts produce your best practice. OVERTIME MODE The bell rings when your timer ends — but you don't have to stop. Continue as long as you want. Heart Sit counts the extra time and saves your full duration. EVERY DETAIL • Real-time BPM display + radial heart rate wave that shifts blue when calm, red when active • Optional haptic heartbeat — feel your pulse with every beat • Set an intention before sitting; recall it after • Session history with full per-second heart rate charts • Heart Rate Variability (HRV) reading per session • CSV export for power users • Beautiful share card — poster of your session • HealthKit integration: every session saved as a Mind & Body workout • Pure black, Georgia serif. No clutter. No animations to distract you. PRIVACY No accounts. No cloud. No analytics. No tracking. The app makes zero network requests. Everything stays on your device. NO SUBSCRIPTION. EVER. This isn't a wellness app trying to monetize your meditation. It's a measurement instrument for people who already have a practice. Download once. Use forever. REQUIREMENTS • AirPods Pro 3 (or AirPods Pro 2 with USB-C and HR-capable firmware) for live heart rate via earbuds • Apple Watch for live heart rate via wrist (any HR-capable model) • iPhone running iOS 18.0 or later Without either AirPods or Watch, Heart Sit works as a beautiful meditation timer with the same overtime mode and session journaling. For serious meditators who want evidence, not affirmation.

BeatZone connects to any Bluetooth heart rate monitor — including WHOOP, Polar, Garmin, and more — and gives you real-time alerts when your heart rate leaves your target zone. Set your low and high thresholds, and BeatZone does the rest. A pulsing heart animation shows your live BPM, color-coded by zone.

Key features: • Connects to any standard Bluetooth Low Energy heart rate monitor • Live heart rate display with animated heartbeat • Configurable low and high HR thresholds • Instant alert when HR leaves your target zone • Recurring alerts at a customizable interval while out of zone • Choose from 5 alert sounds or go silent • Optional iOS notification banners • Works in the background via BLE and local notifications and/or alert sounds • Dark UI designed for mid-workout glanceability • All data stays on your device — no account, no cloud Whether you're doing zone 2 cardio, staying in a fat-burning range, or keeping intensity below a ceiling, BeatZone keeps you honest without having to stare at your watch.
