About this app

Level Hub is a professional application that connects to our "Digital UnLimited Level" measuring instrument via Bluetooth to display, manage, and calibrate measurement values. By combining this application with the Digital UnLimited Level, it functions as a digital level for measuring inclination.

Main Features

[Connection Management] Automatically detects nearby Digital UnLimited Levels and allows simultaneous connection and management of multiple units. A custom display name can be set for each measuring instrument. Automatic connection can be switched ON/OFF.

[Measurement Value Display] Measurement values ​​for 1-axis or 2-axis measurements from multiple units can be viewed on the same screen. Supports switching between card and list displays, and customization of display units and digits.

[Target Value/Tolerance Setting] Set target values ​​and tolerances for each measurement axis, and verify on the screen whether the measurement values ​​fall within the range. In addition to the standard setting, alternate zero is supported. An arbitrary position can be set as the reference (zero point) (limited to within the measurement range).

[Calibration] Perform user calibration by selecting multiple units at once. The process is guided, and calibration status can be managed for each device.

[Display/Operation Settings] You can check and change themes, default display units, and version/license information.

[Automatic Processing] Acquisition of Factory Calibration Data
Factory calibration data for the connected Digital UnLimited Level is automatically acquired from our server upon connection. If acquisition fails, you can reacquire it within the app.

[Operating Environment]
* Android 7.0 or later (Android 12 or later recommended)
* Bluetooth Low Energy compatible device / Digital UnLimited Level (sold separately)

[Measurement Specifications]
The number of measurement axes, measurement range, accuracy, and resolution vary depending on the product specifications of the connected Digital UnLimited Level.

[Privacy]
• No user account required
