iSpeed Pro is engineered for precision, offering more than just a speedometer - it’s a complete situational awareness tool for drivers, boaters, and tech enthusiasts. By combining real-time velocity, lateral G-forces, environmental data, and a high-precision performance timer, it reduces eye strain and keeps your focus where it belongs: on the road or the water. Just drop your iPhone or iPad on a dashboard for the stylish HUD display on a windshield, right in front of your eyes! Whether you are navigating the highways or cruising open waters, iSpeed Pro provides a crystal-clear, lag-free instrument cluster optimized for both iPhone and iPad (including full ProMotion 120Hz support for the iPad Pro and iPhone 17+). KEY FEATURES: PRECISION ANALOG DIAL: A high-visibility gauge featuring 10-unit dividers and a dynamic, spring-animated needle. Designed for instant readability at a glance, now with the Fighter Jet Silhouette. HEADS-UP DISPLAY (HUD): One-tap mirroring flips the entire interface, creating a crisp, professional reflection on your windshield for safer night driving. TIDAL DISPLAY: View tide levels for your current location with hourly updates. HYBRID PERFORMANCE TIMER (G-SENSOR TRIGGER): Achieve the highest precision 0-60 MPH (0-100 KM/H) times. Our proprietary Hybrid logic uses the accelerometer to trigger the clock with zero lag, while GPS is used to complete the run with professional-level accuracy. LIVE MARINE COMPASS: A professional rotating-card compass keeping your bearings clear regardless of device orientation. ADVANCED WEATHER & WIND: Real-time temperature and wind data powered by Apple Weather. Stay informed of local conditions in both Fahrenheit and Celsius. CROSSWIND ALERTS: Drive with confidence. iSpeed Pro features an intelligent "High Wind" caution system that triggers when gusts exceed 20 MPH. ALTITUDE: Feet or Meters. SMART-SPEED ALGORITHM: Custom logic ensures rapid startup and speed reporting, providing a "Fast-Start" experience. WHY CHOOSE ISPEED PRO? Unlike basic GPS apps, iSpeed Pro focuses on the Cockpit experience. By combining navigation, environmental data, G-forces, and velocity into a single neon-optimized interface, it minimizes distractions and maximizes safety, especially during nighttime driving or other challenging conditions. PRIVACY & DATA: Your privacy is our priority. iSpeed Pro uses your location data strictly for real-time speed and heading calculations. We do not store, track, or share your personal movement data. The G-force and performance data is processed entirely on your device. We support Ukraine
