There is only one TinyDB database per app.

You can create new tag names for your data and set them to lists of values of unlimited length.

Or is your question about how to enter more than one value into a single TextBox?

TinyDB tutorial by Stephen

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.

first learn the basics, doing the tutorials usually helps...

then try something and if you get stuck, post a screenshot of your

relevant

blocks

How about you store a list under a unique tag in TinyDB?

Then you can keep adding items to that same list later.

Wait, what you want is to JOIN previous text with new text, right?

Use the JOIN block to add the new text in textbox2 at the end of textbox1.

If you think a little, you will realize you are giving the answer to your own question:

JOIN the old value stored in TinyDB + the value of textbox1 + the value of textbox2 and store this JOINED text in TinyDB again.

Next time you will retrieve that joined text you just saved as the old value, and will repeat the process.

The last two screen captures are after the app was closed then reopened and shows that the previous text was saved.
