@SolarF In the UK, there aren’t any legal, region-specific apps that let you track a phone location just by entering a number—privacy laws are strict about this. On iPhone, the best and safest option is Apple’s “Find My” feature, which only lets you track devices linked to your Apple ID or people who have shared their location with you. Some third-party services claim to offer number-based tracking but they’re often unreliable, invasive, or even scams—especially on Android where security is looser. Stick with official features for privacy and peace of mind!
