OneTouchGate is a smartphone application designed for iPhone users. Developed by Hyunha Shin, this free app falls under the category of Utilities & Tools. With OneTouchGate, users can conveniently and securely open the main entrance door of their apartment or office building using Bluetooth Low Energy (BLE) communication.

To unlock the communal entrance door, simply launch the app, log in, and tap the "OPEN" button on the main screen. However, before being able to use this feature, users are required to complete the registration process and add their building's main entrance door to the app.

It's important to note that the Bluetooth functionality of OneTouchGate is exclusively used for opening communal entrance doors and is not utilized for any other purposes.
