Thank you for your support of Codebook and for posting on the discussion forum. Your purchases of Codebook for iOS’s should be tied to your Apple ID. Do you happen to know if you’re still using the same Apple ID on your iPad as you’re using on your iPhone?
The icon on my phone is blue. So I think I have the right app.
Yes the blue icon is the correct universal build.
If you’ve already purchased the universal version of Codebook separately, you should be able to download it without cost on your iPad (as long as it’s using the same Apple ID). Could you visit this link: https://itunes.apple.com/us/app/codebook-password-manager/id316817719?mt=8 on your iPad and see if you’re able to download it without cost and complete the migration process.
If you’d prefer, we’d also be happy to assist further in private support email@example.com
