how do i undo an app update

You cannot

1. Delete the newer, undesired version of the app on the iPod or iPad by touching the icon until apps start to flash on the device screen and then touch the "X" on the app to delete it.

2. Plug the iPod or iPad into the Mac.

3. Open iTunes

4. In iTunes, click on the iPod or iPod listed under "DEVICES" to select it.

5. In iTunes, click on "Apps" in the header of the device window at right.

6. Scroll down to find the name of the App, which will have the box to the left of its name unselected (which means it was deleted on the device).

7. Click that empty box to select it with a checkmark showing.

8. Click "Apply" at the lower right in the iTunes device window to restore the previous version to the device.

9. Wait for the sync to complete.

The older version will be restored on the iPod or iPad device.

Seems like that would only work if the app was updated through the phone and not yet synced with the Mac and not updated via iTunes on the Mac, otherwise the sync would just reinstall the undesired update. In this scenario, how does one go about reloading the previous version of an app that was updated and synced yet the update is no longer desired?

Then you have at least two choices:

- be sure you back up your laptop regularly, and restore the ipa file from your mac backup OR

- before you upgrade your iDevice, make a backup copy of the app's ipa file on your mac so that you can restore it if you hate the update.

The ipa files on your mac are located at:

User > Music > iTunes > Mobile Applications.

As you can see below in other people comments it can be done. I just did it ...

Thank you very much. It's working like a champ. Great job bro !

How to undo a update for a app

What if I don't have a Mac, would it work on a chrome book or some other laptop?

You will need iTunes. So any laptop will be fine as long as you have used it to backup your iPhone/iPod or iPad. I don't think Chrome Book will be helpful in this case.
