QR Thing
Read full descriptionHide full description
This application lets you scan and create QR codes, without spying on you or showing you ads. When creating QR Codes, multiple design aspects can be changed like pixel shape, thickness/scale and foreground and background colors. You can also add a custom logo to your QR code. The QR code can then be exported/shared as PNG or SVG without additional cost, registration or anything else being required unexpectedly. It's the perfect app if (and I wrote it because) other apps disappoint with lock-in, spying, ads or outright scams (like pretending to create a code containing your URL, but it points to their domain so they can extort you later on).
cURL Send

cURL Send is a fast mobile API client built for developers who want to test requests directly from iPhone. Paste a cURL command from your clipboard, review the method, URL, headers, and body, then send the request in a focused mobile workspace. It is designed for quick API checks, debugging, backend testing, webhook inspection, and working with REST endpoints when you are away from your desktop. Import cURL instantly Paste a cURL command from your clipboard and turn it into an editable request. cURL Send parses the request into clear fields so you can inspect and adjust the method, URL, headers, and body before sending. Test APIs from your iPhone Send HTTP requests and view response status, headers, and body in a clean dark interface. JSON responses are formatted for easier reading, with response search to help you find fields quickly. Save response values Capture supported JSON response fields into a global container. Save IDs, tokens, status values, or other response data under reusable keys. Reuse values in headers Use saved global values in header fields for follow-up requests. This helps with common API workflows like saving a user ID, session value, token, or other response field and reusing it in the next request. Built for mobile API workflows cURL Send is ideal for: - Testing REST APIs - Debugging HTTP requests - Inspecting JSON responses - Running copied cURL commands - Reusing response values in headers - Checking backend endpoints from iPhone - Quick API validation without opening a desktop tool Whether you are debugging a backend service, checking a webhook, validating an endpoint, or testing an API while mobile, cURL Send gives you a simple cURL-first workflow on iPhone.
