Im making an app where it reminds me of the things i need to do, but i want it to set an alarm for me, is there a way?
For example:
Clean the house
At? (chooses 10:00 am)
Press here to set an alarm at 10:00 am
You just don't with App Inventor Blocks unless you never allow the app to sleep. App Inventor cannot run in the background without using extensions.
What you can do if you are brave https://community.appinventor.mit.edu/search?q=alarm
do i have to pay for the Alarm extention? im using a pop up extention that a guy made, which is very useful, but in my undestanding, i cant make the app i wish for without paying?
what about trying the alarm extension?

Yes, you have to pay for Taifun's Alarm extension .
Supposedly (if you dare) you can use this which can probably run your alarm Background Tasks extension [3.8 A] 🥳 - #292 by iomedesimo . It is free.
there is a free version and a paid version of the alarm extension available...
the free version might be sufficient for your needs...

There isn't a free extension for this?
No, but you could write your own extension and create the functionality yourself...
more information about how to create an extension see the App Inventor Extensions document
however that will be more advanced and will require some Java skills...
