GPS Speed Camera is a Taiwan-focused all-in-one app combining speed-camera alerts, navigation, traffic info, and dashcam recording, keeping your eyes on the road while everything else is integrated into one screen. ■ New "Dashcam Mode" (v2.0) One tap turns your iPhone into a car-mounted camera, with speed-camera alerts, speed, GPS coordinates, and road name overlaid live onto the recording: Loop recording: 3-minute segments, keeps only the latest 5 (auto-rotates when full) In-app playback anytime Export with overlay: speed and alert info gets burned into the video file for sharing, instant evidence after an incident Microphone audio included; speed-camera voice prompts are captured too Note: Dashcam runs only while the app is foregrounded and the screen is on (an iOS limitation common to every phone-based dashcam app). A car charger is recommended. ■ Comprehensive Speed-Camera Database Covers fixed, mobile, average-speed zone, tech-enforcement intersection, and unlimited-speed camera types. This version brings a major database refresh, with many new tech-enforcement points and newly installed cameras across Taiwan added, and duplicate entries cleaned up for more accurate alerts. ■ Smart Voice Alerts Voice prompts trigger at an appropriate distance based on your speed and preferences; works with Bluetooth headphones and speakers. ■ Map and Navigation Integration Speed-camera positions, construction zones, and incident points show directly on the Apple Map, with iOS native traffic colors (orange for heavy traffic, red for congestion). Built-in navigation means you don't need a second app. ■ Real-time Traffic Info Highway driving: detects traffic conditions within 5 km City driving: detects within 3 km Lets you reroute early to avoid congestion. ■ Community-Driven Reports Report new or changed speed cameras directly in the app; we review and update the database periodically. Traffic reports are also crowdsourced, so drivers look out for each other. ■ iPhone Dynamic Island and Live Activity Speed, alert info, and average-speed-zone progress show on your Lock Screen and Dynamic Island; no need to unlock to check. ■ Multi-Language Traditional Chinese / English / Japanese / Korean, auto-switching by system language; can also be set manually in-app. ■ Privacy Compliance On first launch you'll see standard Apple App Tracking Transparency and ad-personalization consent prompts (for EU GDPR). Your choices do not affect core features. ■ Features Taiwan-wide speed-camera alerts (fixed / mobile / average-speed zone / tech-enforcement / unlimited-speed types) Real-time speed display Apple Map integration and navigation Dashcam mode (recording + speed-info overlay + loop segments + export and share) Real-time traffic detection (5 km on highways / 3 km in cities) iOS native traffic-color indicators User-driven speed camera and traffic reports Online database updates downloadable in-app Background operation (map mode keeps detecting in background; dashcam mode requires foreground) Voice alerts with Bluetooth headphone / speaker support System alert notifications iPhone Dynamic Island and Live Activity display Multi-language auto-switching Let GPS Speed Camera be your driving companion, from speed alerts to dashcam recording, all in one app.
