Kat is the best thing to happen to your API workflow. Its a full-featured iOS app to test any REST service. It doesnt matter if youre developing an app to connect to an API or developing the API itself, with Kat you can create a request and examine the response.

Kat supports GET, POST, PUT and DELETE requests with headers, bodies and parameters. It can display data in a special JSON view, text with syntax highlighting or render the html for you.

Kat is designed to work on iOS 9 and 10, so you too can have the freedom of developing on the iOS platform. Kat is the second app of the ‘Developer pets’ collection, and can be purchased together with a discount. I would love to hear your thoughts about Kat, and if there are any pets that you are still missing on iOS!
