QR Reader & Code Generator vs Platterset

QR Reader & Generator is a fast, private, and completely free QR and barcode app. No ads, no data collected, no account. SCAN ANYTHING Scan QR codes and barcodes with your camera or straight from a photo. Pinch to zoom, tap to focus, batch scan, and use the flashlight in the dark. SMART RESULTS The app understands what you scanned: join Wi-Fi, save contacts, add calendar events, open locations in Maps, and look up products. Copy any field with one tap. LINK SAFETY CHECK Every link is checked on your device before it opens. Shortened links, lookalike domains, and other phishing tricks are flagged. Nothing is ever sent to a server. CREATE YOUR OWN QR CODES Make codes for links, Wi-Fi, contacts, email, SMS, phone, location, and calendar events. Pick colors and styles, preview live, and export as PNG or vector SVG.

Private by design — no ads, no tracking, no data collected.

Alignment Lab compares tonearm geometry trials across your chosen groove span. Inspect tracking-error curves and export every sampled point with the actual inputs. HOW TO USE THE UPGRADE 1. Open Align → Alignment Lab. Enter the pivot distance and groove span for the record format. 2. Compare one to six trials using bundled null-point references or custom null radii. Inspect the curves and geometric values. 3. Save the comparison and export the CSV. Follow your turntable and cartridge instructions for actual adjustment. Alignment references, overhang tools, record-format references and other turntable setup tools remain. Existing setup records are preserved under Earlier setup records. WHAT TO KNOW Curves sample 401 points and report sampled peak and unweighted RMS angular error. They are theoretical geometry, not audible distortion, cartridge compatibility, setup accuracy or sound-quality scores. One to six trials and up to 50 sessions. Earlier setup records remain accessible as historical heuristic worksheets. iPhone and iPad. No account required.
