How can I transfer string from Blynk to MIT?

I am doing the weight IOT similar to this project;

I already able to upload my string to the Blynk. Can somebody help me to send the string to mit app? Ive been using a pin V3 in blynk.

Wouldn't it be better to use one or the other (Blynk or App Inventor) for your project? They are both there to make the App side of the project.

is there possible to do that cause iam still new with mit😭

Yes it is possible to do that with an App developed with App Inventor.
