What's New in Cown Zoo

1.5

January 4, 2026

- Set execution context (@inject-into) for your script. Zoo Runtime API is now only available when running in Content Script context. - Script injection engine has been rebuilt from scratch. It’s much faster and much less error prone, and runs on newer iOS versions. - Tweaked design to adopt Liquid Glass on iOS 26. - Popup now shows script injection status if the script failed. Zoo now supports iOS 17 and later. Thank you for your patience and support.

Don’t buy this app!

It don’t work! After the last update, the developer broke it and it don’t work anymore. It’s a total waste of money!

Hello, in our testing it works fine. Would you please describe what is not working more specifically, with your iOS version info, so we can look into it? We’d be very happy if you can reach us at zoo (at) cown.app.
