Httper is a versatile REST API test app designed for iOS devices, allowing developers to conveniently test their REST APIs on-the-go without the need for a desktop PC. With Httper, developers can easily submit HTTP requests complete with headers, parameters, and raw request bodies. The app provides the HTTP response in four different styles: pretty, raw, preview, and detail, catering to various developer preferences.

Moreover, Httper offers a project feature enabling users to group requests together within a project. By signing in to their account, developers can seamlessly synchronize projects and requests across multiple devices. Additionally, Httper includes a range of Internet tools such as domain/IP pinging, Whois search, and retrieving device public IP, WiFi, and cellular information.
