Real-Time GPS Tracking Solution

I need a dependable way to see one person’s whereabouts at any moment. The priority is GPS tracking only; no social-media or online-activity monitoring is required. The person carries a smartphone and also drives a car, so your solution must cover both devices seamlessly on the same map interface.

Here is what I expect:
• Continuous, real-time location updates with minimal latency.
• A single dashboard—web or mobile app—where I can switch between the phone’s location and the vehicle’s tracker.
• Simple installation: clear instructions for any hardware you recommend for the car and step-by-step guidance to activate the phone component (Android and iOS preferred).
• Secure data handling and password-protected access.
• Option to export location logs if needed later.

Please detail which GPS hardware, SIM/data plans, and software stack you propose, along with estimated setup time. I will test by confirming live positions from both devices; once accuracy and reliability are verified for 24 hours straight, the project is complete.
