Which ANDROID application to communicate with the XIAO ESP32 C3 via Bluetooth

Hello to all,
I use the little wonder called XIAO ESP32 C3
I am exploring the possibilities it has in Bluetooth.

First unsuccessful attempt with BluetoothSerial.h : no compilation.
Then I found the Seeed tutorial:

And it works !

My question: the ANDROID LightBlue application works perfectly, but is not an example of ergonomics. Is there another application more user-friendly, like Serial Bluetooth Terminal?

Thank you for your answers,
