Now I tried something:
Is this correct? And now how do I activate the clock1 to send the "notification" to the user at that time?

Great
To get a better understanding of how to work with date and time, do this tutorial
And learn how to use Do it
use Do it to debug your blocks, see also tip 4 here App Inventor: How to Learn | Pura Vida Apps
see also Live Development, Testing, and Debugging Tools
Then use the FormatDateTime method from the Clock component and show us a Do it result of that instant you just stored in TinyDB and compare the result with what you get after using Clock.Now

Why is my 'do it' option grey? I can't select it.
You need to connect by Companion or emulator.
that is a problem because I only test my app by building it.
but didn't you told me I had to convert the timedate into millis? Also, where do I put those blocks you just sent?
Yes, because you want to store it in TinyDB
However first to have to
Therefore read again my previous answer and
Taifun
Understood but I still don't quite understood how to make 'Do it' work...
Also, sorry for all the questions but wouldn't the instant that I stored be different from the one I get on those blocks (since the clock will give the instant moment and the one I store is introduced on the timepicker by the user)?

Is it this? I did the do it of the blocks you sent at 03:01 PM and the hours i introduced in the time picker was 03:03 PM...
Ok, you made some progress... very good...
Now compare the millis of the 2 instants or the FormatDateTime of the 2 instants
You will find out, that the date part of the timepicker instant is missing... to be able to compare the 2 instants, you have to add the date therefore
The timepicker gives you only an instant of time, but not of datetime
Taifun
Soo... What do I have to do exactly?
Taifun
Let's assume, you like to get the instant of today, 3pm
Take the datetime of today which is 2024-06-13 00:00, convert it into the format you need (see the 2 options below) and add the time received from the timepicker, which is 3pm
As always there are several possibilities to do this
-
convert both into millis and add the millis to get the millis of that datetime
-
use one of the methods from the clock component to add the 2 instants to get the instant of that datetime
Let me suggest you to start trying something

Isn't there a simpler way to send a notification to the person at the time she chose in the timepicker when she submits the medicine? Also, I visited the 'How to use the CLOCK' tutorial and didn't quite get it how it works... I even downloaded the .aia but it didn't show what I wanted to do soo...
To add a date and the time received from the timepicker to get the alarm datetime is a simple addition like 2 + 1, it does not get simpler...
If you only visit the clock tutorial without doing anything you will not learn much...
Start doing something...
Taifun
To find out what you are doing, convert the millis into a readable format using the FormatDateTime method
If you do this exactly at midnight, then yes ..
Remember:
Taifun
What should I change then?
