Do you work with QR codes or other types of scannable codes as much as I do? Do you need to see the data encoded in your codes for quick testing without your device or other fancy apps trying to take you to a website or somewhere else? Then this is the app for you! I needed an app like this, so I wrote one, and you get to benefit from my need. Features: * Scan a code with your device's camera and see the data encoded in that code * See the image your device's camera captured when it scanned the code * Copy or Share the data or the image with the new Share Sheet (iOS 16 only) Supported Codes: * QR * UPC-E * Code 128 * Code 39 * Code 93 * PDF417 * Code 39 mod 43 * DataMatrix * EAN-13 * EAN-8 * Interleaved 2 of 5 * ITF14 * Basically most of the codes defined by AVMetadataObject.ObjectType Directions: 1. Open the app 2. Tap the scan button in the lower right corner of the app to open the scanner 3. Aim your camera at the code you wish to scan 4. Attempt to contain your excitement as the data appears on the screen

This app’s name is an homage to the world’s first web server. Back in 1989, Tim Berners-Lee started the web on his NeXT computer. On that computer was an app named WorldWideWeb. This app was unique because it allowed his machine to edit and serve HTML documents. The app also used coding frameworks that were adopted by Apple after purchasing NeXT: they are being used right now to display what you’re reading. Like that original app, this WorldWideWeb is a handy web development tool. It’s designed for people who need to test things on their iPad or iPhone before moving the files onto a real web server like Apache or nginx. It also allows you to work in those increasingly rare moments where you don’t have a connection to the Internet. App developers can use this server to simulate and test APIs that their product uses. FEATURES WorldWideWeb does things differently than today’s production web servers: • Automatic refresh — Watches your site and reloads browser when there are changes • No caching — Every request gets a new response, no cache busters needed • Easy to configure — Pick a folder and go • Directory listings — A handy list of files whenever you hit a URL that doesn’t exist • Bonjour support – Automatic DNS for easy access using devices on your local network • REST support — Set default responses as JSON or XML for easy mocking of APIs • No external dependencies — Completely standalone and doesn’t need other tools like Python or Ruby • Built-in security — Runs completely in a sandbox, no access to data unless you allow it • Powerful and lightweight – A small memory footprint with minimal CPU overhead • No rocket science — Perfect for clients and other folks who are less technically inclined

Verdict
The clearest difference is in-app purchases: QR Debug at none against WorldWideWeb's 1. QR Debug also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 76%). WorldWideWeb's advantage is update cadence (every 4 months vs every 15 months) and ratings volume (39 vs 5). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. WorldWideWeb sells 1 one-off in-app purchase. QR Debug asks for nothing beyond the download.
QR Debug holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: WorldWideWeb has 39 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 100% of QR Debug's written reviews are positive against 76% of WorldWideWeb's.
QR Debug ships an update every 15 months, WorldWideWeb every 4 months. The most recent releases landed on September 30, 2026 and October 13, 2026 respectively.
