Developer Tools helps you test servers, API calls, clients, and more. For each GET/POST request, it displays the JSON response in a user-friendly viewer. The JSON viewer supports all common data types, including lists, dictionaries, integers, doubles, and strings. It also shows the path to each element, making it easier to implement paths programmatically. The app also allows you to host an HTTP server directly on your phone and provides the IP address for connection. This is especially useful when testing data sent to a server or when getting started with server integration. Additionally, the app lets you generate and save QR codes. If any issues arise, or if you’d like to request a new feature, feel free to send me an email directly from the app’s home page.
