User interaction with a BLE device

Hello everyone!
I am developing a device that reads readings from a sensor and sends parameters via BLE.
It is necessary to develop an interface for interacting with the user, and this does not have to be a native application.
I thought to implement this via Web-Bluetooth API, but this is not suitable since there is no internet access.
What implementation paths can be used with minimal user effort?
