Why oh why do they insist on updating the Tapatalk app? My favorite version ever was 3.0.1, followed closely by 3.2.1. The piece of crapware they are now pushing is horrible - layout is atrocious, they offer no way to turn off the internal notifications, and despite having paid for the version previously, I'm stuck looking at all of their ads. However, I found an easy way to prevent it (or any other app) from updating via iTunes... simple and straight forward: Find the old version of the app in your iTunes library or your TimeMachine backup. (The default location will be Music > iTunes > iTunes Media > Mobile Applications > appname). Make a copy of this file outside of this folder just in case. Then make another copy of it on your desktop. Make sure you have file extensions on so you can see the .ipa extension. Change the .ipa extension to .zip and extract the folder Download a plist viewer. I downloaded the free lite version from plist Editor - reading and edit plist files for Windows. On my Mac, I use BBEdit, but any editor that is compatible with .plist files will work fine. Open the folder you extracted and open the iTunesMetadata.plist with the plist editor. Search for the <itemId> tag and change the number inside the <integer> </integer> tags to anything. I just use 54321. Save the file. Zip the CONTENTS of that folder back up. Change the file extension back from .zip to .ipa. Delete Tapatalk (or other app) from your iOS device first. Double click the new .ipa file you just made and iTunes will ask if you want to replace it. Hit yes and drag it onto your device. Sync your device, and you're good to go. Because the ItemID will never match the iTunes store info for that app, it will never update. If you ever want to abandon this and get the latest and (maybe not so) greatest version, just delete the app from your iOS device and re-download it from the App Store.
