how do I delete duolingo.. it does not want to leave

Hi there,

Apple's website provides instructions on how to delete apps here: https://support.apple.com/en-us/HT207618

On your device hold your finger on the App until you see a dialog box appears and one of the options will be Delete App. Tap that and the app will delete.

Go the Duolingo's account settings==> Click on account==>find and option"DISABLE MY ACCOUNT"==click ok ==> after that==> click on "delete my account"==>click okay
