PentaRace

PentaRace is a clean, focused GPS tracker for runners, cyclists and hikers. No bloat, no ads, no subscriptions — just the metrics that matter, beautifully laid out on your phone.

LIVE TRACKING
Start a session and watch your duration, distance and speed update in real time on a full-screen map. Your route is drawn live as a clean cyan polyline, with your direction shown by a smart user marker that follows your heading.

FOCUSED METRICS, SPORT-WATCH STYLE
The top stats bar shows the four numbers you actually need — duration, distance, speed and calories — in big, monospaced digits inspired by sport watches. The bottom bar keeps secondary info compact: textual compass with cardinal direction, current altitude, action buttons, and quick access to your history.

HEART RATE SENSOR SUPPORT
Pair any standard Bluetooth Smart heart rate sensor — Polar H10, Garmin HRM-Pro, Wahoo TICKR, Suunto Smart Sensor, Polar Verity Sense, or any sport watch in heart rate broadcast mode. Connection is automatic — no manual pairing screens, no proprietary SDKs. PentaRace uses the standard Bluetooth Heart Rate Profile that every certified sensor on the market supports.

When connected, your live heart rate appears in a colored effort zone banner under the main stats — gray for warmup, green for endurance, yellow for cardio, orange for threshold, red for maximum. The zones are computed from your maximum heart rate using the Tanaka formula.

ACCURATE CALORIE TRACKING
Set your fitness profile (age, sex, weight) once and PentaRace estimates calories in real time during your activity:
• Without a heart rate sensor — based on metabolic equivalents adjusted to your GPS speed
• With a heart rate sensor — using the Keytel formula for precise sex-aware energy expenditure
Calories show a tilde (~) when estimated, and switch to a precise figure as soon as a heart rate sensor connects.

HEALTH APP INTEGRATION
Every saved activity is written as a workout to the Apple Health app, including the full GPS route. Your runs, rides and hikes show up alongside your other activity data, contribute to your activity rings, and stay private on your device.

ACTIVITY SYNC ACROSS YOUR DEVICES
All saved activities sync automatically across your devices via iCloud. Browse your history, view detailed charts of speed, altitude and heart rate over time — with effort zones overlaid on the heart rate chart so you can see exactly where you pushed and where you cruised.

SHARE BEAUTIFULLY
Generate a polished image of any activity — map snapshot, stats, title — and share it through the native share sheet to messages, photos, or any social app.

MODERN DESIGN
Built natively from the ground up with fluid surfaces, smart animations and clean typography. The interface adapts cleanly to your phone — designed for portrait and landscape, optimized for one-handed use during your activity.

PRIVACY FIRST
PentaRace never sends your data anywhere except iCloud (your account) and the Apple Health app (your device). No analytics, no third-party SDKs, no tracking domains. Your fitness profile stays on your device and your iCloud — period.

Whether you're heading out for a 5K run, a long Sunday ride, or a weekend hike, PentaRace gives you the tools to track it without getting in the way.
