How can i make a app that controls motors of arduino

I am learning arduino and wanted to make an rc car but dont know how can i make an app in mit app inventor that controls it through bluetooth or anything else. please suggest

Have you seen yet?

I created a playlist on my channel about Arduino AppInventor 2 via Bluetooth, from the connection to sending and receiving digital and analog data (including texts) and with a small HMI. Maybe this can help. You can use the digital and analog outputs to control the car engines
