App Slow on Thunkable prototype tester

I am trying to develop an app for a class that reminds users with special needs to look both ways when they reach a crosswalk or location that has been added as a location to warn users at.

My group tested the app using the Thunkable mobile prototype app, but have found its too slow to function effectively. Is there a way someone can look at my code and help debug why it is so slow? (Almost takes a minute to load opening screen) Or do you all know if the app would speed up should I get an apple developer account and download it?

There is a little time crunch since the project is due in 2 weeks, so a speedy response would be so greatly appreciated.

There is enough Code it is difficult to get screenshots of all of it - essentially I save gps coordinates in an Airtable and then check if anyone is within 3 meters of any point every second. It works (sometimes) but because it is so slow it is very inconsistent.

Thanks for any assistance and I can send code if that’s helpful!

Can you post a link to your project?
