PERFECT FOR • Runners in areas with poor GPS signal • Indoor track running • Trail running in dense forests • Urban running between tall buildings • Anyone who wants reliable tracking in all conditions HOW IT WORKS Running Voice uses both GPS and your iPhone's pedometer to track your runs. When GPS signal is strong, it uses that for maximum accuracy. When GPS is weak or unavailable, it seamlessly switches to step counting so you never miss tracking a run. Voice announcements automatically lower your music volume, give you updates, then restore your music - all without you touching your phone. ANNOUNCEMENTS SCHEDULE • First milestone: 10 meters (or 30 feet) • Regular updates: Every 500 meters (or 0.5 miles) • Final summary when you finish Each announcement includes your current distance, speed, and pace, plus a motivational message to keep you going! REQUIREMENTS • Location permission (for GPS tracking) • Motion & Fitness permission (for step counting) • iOS 17.0 or later WHY RUNNING VOICE? Unlike other running apps that fail when GPS signal drops, Running Voice adapts. Whether you're running through tunnels, between skyscrapers, in dense forests, or on indoor tracks, your run keeps tracking. The combination of GPS and step counting means you get the best of both worlds: GPS accuracy when available, and reliable step counting as a backup. The voice announcement system is designed for runners who want to stay focused on their run, not their phone. Keep your screen locked, save battery, and let Running Voice tell you everything you need to know. Start your next run with Running Voice and experience the freedom of hands-free run tracking!
