Thunkable has a very useful feature sometimes you dont have a device available with you(at least in my case), in those times you have to open a very slow emulator. Thunkable allows us to preview the apps on the webpage itself which i feel is very useful and should be implemented by kodular too.
Well, I think that it will be difficult to Kodular do it…
But you can try your APP in the browser on this web. You have only to upload the companion APK to the web and run it (https://www.apkonline.net/filemanager.php)
