Hi there gentle folk. I am new to AppInventor. I have successfully followed the instructions in https://appinventor.mit.edu/explore/displaying-maps and it works great.
I am now trying to figure out how to enhance this App so that when MyLocation is in the proximity of the select Address, the phone will buzz to alert me - like a wake me up application for travelling by bus/train. How do I get started to do this? Do I use the LocationSensor.1 block with an embedded Logic block - or something else? Appreciate someone pointing me. Thanks in advance.
Also, out of the several books out there, any recommendations?
