Already own IOS app. Have to pay for MacOS?

Hello, Already paid and using Codebook (ex Strip) on iPhone since years. Now would like to install it on my all new Mac Book. But App Store ask me to pay for it. Is it how it work’s or there’s something wrong ?

Hi @Martin_Masson

Thank you for using Codebook and posting here.

Each platform of Codebook is a separate purchase. The Codebook for Mac license allows installation on up to 4 macOS computers. We offer 14 day free trials of Codebook for Mac located here: https://www.zetetic.net/codebook/#download

Please let us know if you have any further questions. Thanks!

Cheers,
Micah
