OPSATOS

OPSATOS turns your iPhone and Apple Watch into a tactical fitness HUD — a clean, black-and-amber dashboard for your heart, your position, and your pace. LIVE TELEMETRY See your live heart rate, GPS position, altitude, and speed at a glance. Every reading comes straight from your device's sensors and HealthKit — nothing is simulated. PACE GUIDE Set your age and pick an intensity zone, and OPSATOS calculates your safe target heart-rate range. As you move, it tells you in real time whether to hold your pace, speed up, or slow down — and shows how close you are to your optimal, sustainable effort. Ideal for staying in a comfortable zone that moves you forward without overloading your heart. MISSION LOG Review your past hikes, walks, and runs with distance, time, calories, and average heart rate, all in the same HUD style. APPLE WATCH The companion watchOS app puts five live faces on your wrist: map, workout stats, battery, compass, and weather. PRIVACY All your data stays on your device. OPSATOS never collects, stores, or shares it. OPSATOS is not a medical device. Heart-rate zones are estimates based on age and should not replace professional medical advice. If you have a heart condition, consult your doctor before exercising.
