WattPose vs Sporlyst Tracker

WattPose — The AI Cycling Coach In Your Pocket. WattPose uses your iPhone camera and on-device AI to analyze your riding position in real time — while you pedal. No sensors. Just ride. WHAT WATTPOSE MEASURES ▸ Back Angle The lean angle of your torso from vertical. Optimal: 40–60°. Too upright means more drag; too flat means back pain and power loss. ▸ Knee Extension The angle at the knee joint at the bottom of the pedal stroke. Optimal: 140–155°. Protects tendons and maximizes pedalling efficiency. ▸ Knee Stability Lateral deviation of the knee from the ideal line. A wandering knee is a hallmark of hip weakness or saddle mismatch. ▸ Hip Rocking Side-to-side oscillation of the hips. Excessive rocking wastes watts and stresses the lower back. ▸ Head Drop Your head should sit above your shoulders. Drooping signals fatigue and increases the risk of neck injury. ▸ Shoulder Symmetry Equal loading on both sides. Asymmetry reveals muscular imbalances that limit sustainable power output. VIRTUAL CdA & WATTS SAVED WattPose calculates your virtual CdA (aerodynamic drag coefficient × frontal area) directly from your body pose — no wind tunnel required. Calibrate once from your upright position, then watch in real time how many watts you save by getting more aero (calculated at 40 km/h). A lower CdA means less drag and more speed for the same effort. REAL-TIME AI ANALYSIS ML Kit runs entirely on-device (no cloud upload, no latency). The AI skeleton analyses every frame at up to 30 fps and delivers colour-coded live feedback: • Green = perfect form • Orange = minor issue detected • Red = form breakdown, correct now VOICE COACHING No need to glance at your screen. WattPose speaks directly to you: "Relax your shoulders", "Stabilize your knee", "Keep your hips still" — in your language (English & German). Mute instantly with one tap. BLUETOOTH SMART TRAINER Pair your indoor trainer via BLE (FTMS Indoor Bike Data and Cycling Power Profile supported). Live watts and cadence (RPM) feed directly into the efficiency score — giving you a fully connected coaching experience. POST-WORKOUT ANALYSIS After every ride, review: • Your Collapse Point — exactly when and why your form broke down • A personalised Action Plan with targeted exercises (e.g. Clamshells for knee stability; Plank for back and head posture) TRAINING HISTORY & PROGRESS Every session is stored locally. The Stats screen shows: • Total sessions & total training time • Average & best form score • Bar chart of your last 7 sessions • Trend analysis (improving, stable, or declining) BIKE FIT GUIDE An in-app reference that explains what each metric means, how it's measured, and why it matters — with interactive optimal-range bars for every data point. YOUR DATA, YOUR DEVICE All analysis happens locally on your iPhone. No camera data ever leaves your device. Built for road cyclists, triathletes, gravel riders, and anyone who wants to train smarter — WattPose is the personal aero coach that fits in your jersey pocket. Start riding. Start improving.

Sporlyst Tracker turns your phone into the tracking unit for your race. Scan the QR code your organizer sends you, press start, and put the phone away, your position goes to race control and onto the event's live map until you cross the line. REQUIRES A CODE FROM YOUR RACE ORGANIZER This app is not a standalone activity recorder. It only works with a tracking code issued for a specific event, delivered as a QR code or link. If your organizer does not use Sporlyst, this app will not do anything for you. HOW IT WORKS 1. Scan the QR code from your organizer, or import a screenshot of it from your photo library. 2. Press start at the start line. 3. Ride, run, or paddle. Stop tracking when you finish. BUILT FOR A FULL RACE DAY • Runs in the background with the screen off, phone in a pocket or frame bag, app closed. • Battery-aware. Your battery level travels with each position report, so race control can tell a fading phone from a rider in trouble. Below 20% the app tells race control why, then stops itself so your phone survives to the finish. WHAT YOU SEE WHILE RACING • Elapsed time, distance covered, and current speed. • Your next cutoff, the distance remaining to it, and whether you are ahead of it. • A projected finish time based on how you are actually moving. • Your route, detected automatically, with a manual override if officials move you. SOS One button sends an emergency alert with your exact position and bib straight to the organizer's control room. If you have no signal it queues and goes the moment you do, and it tells you when it has been delivered. You can cancel it if you pressed it by mistake. FOR SUPPORT CREWS Assist vehicles get their own mode. Sign in with your callsign, go on duty, and the control room can see where you are when they need to route you to a rider. Support vehicle positions are visible to the organizer only, never on the public map. PRIVACY • Location is collected only while a tracking session you started is running. Stop tracking or sign out and collection ends immediately. • During the event your position, name, and bib appear on the event's public live map, so spectators and family can follow the race. Your result is published afterwards. • Only real satellite fixes are ever sent. The app never estimates, smooths, or invents a position you were not at. • No advertising, no analytics SDKs, no data sold to anyone. • Importing a QR screenshot is handled entirely on your device. The app has no access to your photo library and never uploads an image. IMPORTANT SAFETY NOTE Live positions and control-room alerts are estimates derived from intermittent GPS reports. Positions can be minutes old. Phones lose signal and run out of battery, and mobile coverage fails in exactly the remote terrain where help is hardest to reach. An alert can fire when nothing is wrong, or fail to fire when something is. This app is an aid to race organization, not a substitute for carrying proper safety equipment, a means of calling for help, and your own judgement. Sporlyst Tracker is provided for events run on the Sporlyst race platform. Questions about your entry, your tracking code, or your results go to your race organizer.
