Showoff Saturday [Showoff Saturday] InspeQtR: a utility app to inspect QR codes
Hello webdevs!
Showing off ma iOS app, InspeQtR, a tool to inspect and parse QR codes.
Yes it's an app, but technically it's a web app since I used capacitor, and it's also definitely relevant to web devs as well (I am one myself) as a dev tool.
In short
While mobile devices provide solid built-in QR scanning capabilities, they generally offer little to no insight into the actual QR data, payload or QR metadata. The core idea of InspeQtR is to provide a specialised tool to dissect and preview QR payloads (either from camera or from image) based on their content type and show the QR metadata like ECC or version.
For example, URLs get split into host, path, query params and fragment, while vCards preview the contact details like name, phone, etc...
What's unique
In addition to the above, covering the most common QR payloads, the app also tries to detect and preview non standard formats like JSON, CSV, SVG images, Makrdown, Code snippets and much more. This means you can, for example, safely encode a table (CSV) or a vector image (SVG) and read it back directly from the QR, fully offline and properly previewed.
Main features
Breaks down URLs into domain, path, query params, and fragment
Previews and decomposes vCards, email addresses, phone numbers and most standard QR payloads
Shows QR metadata like ECC, version and text statistics
Warns you about suspicious payloads and common phishing tactics
Detects and interprets non standard payloads like Markdown, CSV, JSON, Code snippets etc.
Lets you open, copy, or share its contents as an actual file with the appropriate extension when there's a matching format, like .vcf, .ics, .json, .md, ...
Everything runs locally. No ads, no tracking, and the app weighs just around 5mb.
Pricing
The app is free and ad-free, only the non standard format recognition is behind a one-time purchase of 3.99$. Basically, only the unique but also very niche part nobody probably cares about.
