1. Is tracking in real time? If devices are nearby, almost realtime tracking is possible. The more devices available, the more accurate the location. If no devices are nearby, tracking is only possible when devices appear nearby (the location update occurs every 5 to 15 minutes). 2. This tracking device is universally compatible with Android and iOS systems. Is there a distance limitation? No distance restriction—it is available worldwide. As long as devices are within a radius of 10 50 meters, the device can be located. 3. Only the owner of the locator can retrieve location data. If multiple devices are nearby, the faster the response, the more accurate the location update will be. 4. How does the device work? The device sends a secure Bluetooth signal every second. Nearby devices (mobile phones, computers, iPads, etc.) receive these signals and upload them to iCloud as a service to generate precise location data.
