Kio Proximity vs NearCast

The Kio Proximity app provides the capability to locate nearby Kontakt.io IoT devices within Bluetooth range of your real-time location. The app determines the proximity of a Kontakt.io device by its RSSI signal strength to your current real-time location, so the closer or farther you move from a device the app will let you know.

NearCast turns your iPhone into a powerful Bluetooth radar. Scan for nearby BLE devices, track their signal strength, estimate distance, and never lose your gear again.
