Delete messages app from ipad

On your iPhone:

Settings > Messages > Text Message Forwarding - set to OFF

On your iPad (and Mac):

Also ensure that Messages in iCloud is disabled on the devices that you do not wish share received or sent messages:

Settings > [Your Name / AppleID] > Messages - set to OFF

After disabling iCloud messages, you can delete all the messages that you don’t wish to be visible on your iPad.

You might also wish to sign-out from Messages on the devices that you do not wish to use the Messages App:

Settings > Messages > Send & Receive > [AppleID] - tap your AppleID highlighted in small blue text, then tap Sign Out

The messaging app itself cannot be deleted (Delete built-in Apple apps from the Home Screen on your iOS 14 or later or iPadOS device or Apple Watch - Apple Support).

But you can just sign out your AppleID in message settings and not use it.

How do I remove messages / iMessages app from ipad? Texting from my IPhone is all I need. I don’t like them on my iPad or computer.

Help! IJ’m understanding why people leave Apple for Android.

Well enjoy your android device then.

There is no need to delete it - I've never used that app and it is just there doing nothing.
