Do I have to download or install any app?

No, you do not need to download or install any app. GeoPhone Tracker is a web-based application, which means you can access its features directly from your web browser without any installations. Additionally, it requires no installation on the target's device and works seamlessly across all device models and carrier types. Simply enter the phone number you want to track or look up, and GeoPhone Tracker will do the rest.
