Thunkable Connecting Personal User data to user profile

I want my Thunkable app (which has a sign in) to be able to access the user’s past info and save their new info (dairy entries, their mood [this is mental help app]), I’m currently using firebase for the authentication but what do I do for saving their information? Also, do you have any additional comments on what I can add to my app. This is being done for the congressional app challenge.

You save their information in Firebase. It’s more secure than Google Sheets or Airtable and you can organize it by user id which is provided by the sign in block in Thunkable.

If you need to know how to structure the data in Firebase, use an LLM such as ChatGPT or Microsoft Copilot to get a start on that.

Is there a video that can help me figure this out by any chance?

Yes, you can find this documentation including an official video by Googling Firebase Thunkable:

I am also currently doing another app where I am adding random Ishihara plate pictures to my Thunkable app. I want the user to input a number as to what they think is in the picture and if it matches up with that picture then it gives me another random picture to test, if I get it wrong however, it gives me pictures in that same category to make sure I have that certain category of color blindness…how would I do this in Thunkable?

Because this is a completely different question, you should start a new topic. There are many steps to this but I would recommend you start by Googling Thunkable quiz because there is a good official tutorial for that.
