API Testing Tools is a fast, private HTTP client for your iPhone, set like a newspaper. Write a request, send it, and read the answer in clean type, with the timings, headers and checks that matter. THE DAILY REQUEST • A front page with today's sends, what needs your attention, your slowest endpoints and the requests you pin, ready to send in one tap. REQUESTS • Every method, query parameters, headers, and JSON, form, XML, text or GraphQL bodies. • Bearer token, Basic and API-key authentication. • {{Variables}} and environments: switch between staging and production in one tap. Built-in {{$uuid}}, {{$timestamp}}, {{$isoTimestamp}} and more. • Paste a cURL command from docs or your browser, or import a Postman collection or environment. RESPONSES • Pretty-printed JSON that keeps the server's key order, raw text with search, image and HTML previews. • Fields: every value in a JSON response with its path. Tap one to check it or save it into a variable. • Status, size and where the time went: DNS, connect, TLS, waiting and download. • Live streams: watch server-sent events arrive as they happen, with event names, ids and timings. CHECKS AND CHAINS • Checks on every response: status, response time, headers, body text and JSON paths. • Save a value from a response into a variable, like a login's token, and use it in the next request. • Run a whole collection in order and see at a glance what passed and what needs a look. AND • A history of every send with its full response, and a filter for what failed. • Copy any request as cURL, or export it as HTTPie, JavaScript, Python, Swift or Go. • Export and import your library as JSON. • Self-signed certificates for local dev servers (optional), cookies, timeouts and redirects under your control. • Light and dark editions. Free, with no ads, no tracking and no account. Requests go straight from your iPhone to the servers you call; nothing passes through anyone else. An optional "Buy me a coffee" tip supports the developer and unlocks nothing.
42 Editor
Read full descriptionHide full description
42 Editor is a code and text editor for iPhone and iPad. It opens the files you already have, in the Files app, iCloud Drive, Working Copy, Dropbox or any other file provider, and saves your changes back to the same file. There is nothing to sign in to and nothing is uploaded. Sometimes the file that needs fixing is a config file, a script or a spreadsheet export, and the only device to hand is a phone. 42 Editor is made for those moments. EDIT IN PLACE • Open a file or a whole folder from any provider in the Files app. Your changes go back to the original. • Opened folders are remembered: create, rename, duplicate and delete files and folders inside them. • Recent files reopen with one tap. • Open in 42 Editor from the Files app and the share sheet. SYNTAX HIGHLIGHTING FOR 29 LANGUAGES Python, Swift, JavaScript, TypeScript, C, C++, Objective-C, C#, Java, Kotlin, Go, Rust, PHP, Ruby, Dart, Lua, R, JSON, YAML, TOML, INI, XML, HTML, CSS, Markdown, Shell, SQL, Makefile and Dockerfile, in light and dark. Line numbers with the current line marked, and long lines that wrap or scroll sideways. A KEYBOARD ROW FOR CODE Tab and outdent, a comment toggle, cursor keys, undo and redo, and the brackets and symbols the iOS keyboard hides. Auto-indent, optional closing of brackets and quotes, and tabs or spaces at 2, 4 or 8 wide. FIND, REPLACE AND FORMAT • Find and Replace, Go to Line, toggle comment, and indent or outdent a selection. • Format or minify JSON, keeping the order of the keys. • Markdown and HTML preview, a tap away. CSV AND TSV AS A TABLE A grid with a pinned header row. Edit cell by cell; add, duplicate or delete rows and columns; sort, filter and undo. The raw text is one tap away. CAREFUL SAVING 42 Editor keeps each file's text encoding (UTF-8, UTF-16 or Windows-1252), its line endings and its final newline. It autosaves two seconds after you stop typing, and if another app changed the file in the meantime it stops and asks which version to keep. iPHONE AND iPAD System, light or dark appearance, font size from 9 to 32 pt, and ⌘S to save on a hardware keyboard. PRIVATE No account, no ads and no analytics. Your files stay on your device and in the providers you choose. 42 Editor is an editor, not a place to run code: it doesn't compile or run anything.

Verdict
The clearest difference is in-app purchases: 42 Editor at none against API Testing Tool's 1. 42 Editor also leads on iOS requirement (17.0 vs 26.0). On price, ads and device support there is nothing between them.
