Heart Plot vs ErgoCam

IMPORTANT: This app REQUIRES a Polar H10 heart rate sensor. Heart Plot is a specialized tool designed specifically for use with the Polar H10 chest strap to visualize your heart’s rhythm in real-time using advanced Lorenz (Poincaré) plotting. By measuring the precise RR-intervals (the time between two heartbeats), Heart Plot maps your heart's behavior onto an X-Y axis. This visualization reveals the "geometry" of your heart rate, allowing you to see patterns that a simple pulse reading would never show. SEE YOUR HEART RHYTHM IN REAL-TIME - Whether you are a "data geek," a fitness enthusiast, or someone monitoring for heart irregularities, Heart Plot provides a live, growing window into your cardiac health. - Detect Irregularities: Easily spot premature contractions, or skipped beats as they happen. The visual patterns created on the Lorenz plot can help identify specific types of arrhythmia. - Capture Episodes: Perfect for users trying to "catch" an intermittent heart event to share with their healthcare provider. - Fitness & HRV: Monitor your Heart Rate Variability (HRV) visually during rest or training sessions. - Built for Endurance: Heart Plot is optimized for long-term monitoring. Whether it’s a quick check, a fitness session, or a 24-hour to 48-hour continuous measurement, the app handles long data sets with ease. KEY FEATURES: - Live Lorenz Plotting: Watch your heart’s "signature" form as the plot grows with every beat. - Stay-Awake Mode: A dedicated toggle to keep your screen on for constant monitoring during workouts or clinical observation. - High-Resolution Data: Captures every RR-interval directly from the Polar H10. - Data Export: Done with your measurement? Download the raw data as a CSV file (including all RR-intervals and timestamps) via the standard Apple Share Sheet for further analysis in Excel, Python, or R. PRIVACY FIRST Your health data is yours alone. Heart Plot does not store your data on any cloud servers. All measurements remain locally on your iPhone until you choose to export them or take a screenshot. MEDICAL DISCLAIMER: Heart Plot is a data visualization tool and is not intended to diagnose, treat, or prevent any medical condition. Please consult with a medical professional to interpret the data. The patterns revealed in the Lorenz plot are for informational and educational purposes. Requirements: - Polar H10 Heart Rate Sensor (Chest Strap) - Bluetooth-enabled iPhone

ErgoCam is a real-time posture coach that uses your iPhone's front camera to spot the bad habits that quietly wreck your back, neck, and shoulders — before the pain shows up. THREE MODES, ONE APP • Phone:catches tech neck (chin tucked toward your collar), screens held too close, and head-tilt strain while you scroll. • Desk: watches your shoulders, chest, and chin in real time. Alerts the moment you slump toward the screen. • Driving: mount the phone on the dash. ErgoCam watches for drowsiness (eye closure, head dropping) and slumped driving posture. Audio-only alerts keep your eyes on the road. CALIBRATED TO YOU • One-tap calibrate per mode — phone, desk, and driving each remember their own baseline, so the app never fires "bad posture" on a healthy variant. • Fine-tune by tapping your shoulders, chin, and chest on a frozen frame. The app uses YOUR anatomy as the slouch reference, not a generic model. • Driving uses a five-point side profile (ear, neck, shoulder, side of upper back, side of lower back) so it understands posture from a dashboard angle. REAL CONTROLS • On/off switches for tech neck and head-tilt detection if a detector keeps firing on a posture you consider fine. • A "back straight" sensitivity slider that scales slouch, forward-head, and chest-gap alerts together. • Sound + haptic, visual flash banner, or silent visual-only mode for meetings. • Reminder pings if you want a gentle check-in even when ErgoCam isn't on screen. DESIGNED TO ACTUALLY STAY ON • Won't go dark — ErgoCam keeps the screen awake while it's watching, so your auto-lock doesn't quietly shut posture coaching off. PRIVATE BY DESIGN • Every Vision computation happens on your iPhone. Camera frames never leave the device — no cloud upload, no account required. WHO IT'S FOR • Remote workers who slump into their laptops by 4 PM. • Anyone who scrolls in bed and wonders why their neck hurts. • Drivers without built-in driver-monitoring — especially long-haul, older drivers, and parents of new drivers. • People who've tried posture-correcting straps and want a smarter, less annoying nudge. Sit up. Look up. Drive safe. • Chin & neck position tracking Helps identify forward-head posture and neck compression. • Eye fatigue & drowsiness detection Monitors eyelid openness and fatigue indicators during long sessions. • Smart wellness reminders Receive posture corrections, stretch reminders, and focus breaks. • Privacy-first design All processing happens locally on your device. No cloud tracking. No recordings uploaded. • Lightweight & automatic Runs quietly in the background while you work. IDEAL FOR • Remote workers • Students • Developers • Designers • Gamers • Office professionals • Anyone spending long hours in front of a screen WHY ERGOCAM? Most people do not realize how often they slouch, lean forward, or strain their neck until discomfort appears. ErgoCam brings real-time awareness to your posture using the camera already built into your Mac. Better posture starts with awareness. ErgoCam — See your posture. Improve your habits.
