QR Forge vs Level Tool

QR Forge makes QR codes — and then proves they work. Every other generator draws your code and hands it over. QR Forge reads its own work back first. After the artwork is rendered — rounded modules, a gradient, your logo through the middle — the app samples that finished drawing the way a camera does and runs it through a complete Reed-Solomon decode. If your content doesn't come back exactly as you typed it, you are told before you export anything. You get numbers, not a badge: • Whether the code decoded back to your exact content • How much of the error-correction budget your styling spent • How it holds up across five off-centre reads, the way a phone sees a code photographed at an angle • Mark strength, contrast ratio, quiet zone and logo coverage • The smallest size you can safely print it FOURTEEN KINDS OF CODE Link, Text, Wi-Fi, Contact card, Email, Message, Phone, Location, Calendar event, WhatsApp, Social profile, App listing, Crypto payment, and Raw for typing a payload byte for byte. Wi-Fi passwords and contact names containing punctuation are escaped correctly — a detail that quietly breaks codes in a lot of tools, because the code still scans, it just carries the wrong data. DESIGN THAT STILL SCANS Six module shapes, five corner frames, five corner centres, linear and radial gradients, adjustable module spacing and quiet zone, and a centre logo with a padding ring. Ten presets, every one of them covered by the project's test suite. Tap "fit the largest logo that still scans" and the app searches for the biggest logo your specific code can carry, checking each size against the decoder — not against a generic rule of thumb. EXPORT PROPERLY PNG at up to 4096 pixels, plus SVG and vector PDF that stay sharp at any print size. Every format included. A SCANNER THAT WARNS YOU Point it at a code and see exactly where it leads before anything opens. That is the answer to a sticker pasted over a real one. NO CATCH Free, with no subscription, no in-app purchases, no ads, no account and no analytics. The app makes no network requests of any kind — there is no code in it that could send your data anywhere. Your library and your logo images stay on your phone. Your codes are static, which means the content is encoded in the pattern itself. They work forever, they work offline, and nobody can switch them off, redirect them, or move them behind a paywall later. OPEN SOURCE The encoder, the scan checker and the test suite behind all of this are public at github.com/keyfive5/QR-Code-Generator QR Code is a registered trademark of Denso Wave Incorporated.

Turn your iPhone into the ultimate measuring toolkit. Nivelo packs 11 precision instruments into one app — no ads cluttering the screen, no unnecessary permissions, just tools that work. WHAT'S INSIDE - Bubble Level — Check any surface in seconds. Three modes: surface, 360-degree, and 3-in-1 view. - Angle Finder — Measure angles with real-time precision using your device sensors. - Protractor — Full on-screen protractor for quick angle readings. - 3D Angle Finder — Measure pitch, roll, and yaw simultaneously in three dimensions. - Laser Level — Project virtual laser lines through your camera for alignment on any wall. - Ruler — Accurate on-screen ruler in centimeters and inches. - Metal Detector — Use the magnetometer to detect metal objects nearby. - Inclinometer — Measure slopes and tilts with degree accuracy. - Compass — Full digital compass with cardinal directions and degree heading. - Plumb Line — Check vertical alignment with a simulated plumb bob. - Barometer — Monitor atmospheric pressure with the built-in altimeter sensor. BUILT FOR REAL WORK Haptic feedback lets you feel when a surface is level. Turn on the flashlight when measuring in dark spaces. Sound alerts confirm level status without looking at the screen. Calibrate sensors for accuracy on your specific device. One app instead of a toolbox full of separate downloads. Whether you're hanging a picture frame, checking a shelf, or working on a construction site — Nivelo has the right tool ready. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
