RestHit (API client) is a free Android application developed by AARK that enables developers to make HTTP/HTTPS requests while developing web or SOAP or REST APIs that are not very easy to make through a browser. It is a lightweight utility tool that allows you to request and check responses of your web or SOAP or REST API with POST, PUT, DELETE, PATCH methods. You can choose the type of content to send in the body, add custom headers and body content, and customize the request timeout and retry policy.

RestHit also offers a beautiful display of the server response in two windows: one for response headers, status code, and network time, and another for response body. This makes it easy for developers to focus on what matters to them and put their learning into implementation. Overall, RestHit is a great tool for developers who want to streamline their API development process and make HTTP/HTTPS requests with ease.
