QR Scene Wallet vs EEPocketworkbench

QR Scene Wallet is a private QR code photo organizer for iPhone and iPad. Save real-world QR scenes from Photos or Camera, add tags and notes, and quickly find parking codes, Wi-Fi codes, tickets, passes, membership QR, event codes, and more. BUILT FOR REAL QR SCENES Screenshots and camera rolls get messy. QR Scene Wallet keeps important QR code images in one local archive, with the original photo as the main content. It is made for remembering and retrieving the QR scenes you already use in daily life. KEY FEATURES • Import QR scene images from Photos • Capture new scene photos with Camera • On-device QR detection that works offline • Save image-only items when no QR code is detected • Add titles, tags, and notes to every item • Browse with list and grid views • Search by title, tag, note, and QR content • Copy detected QR text when available • Export to Photos or share the original image • Replace an image from the detail screen • Save up to 100 items on each device • Supports 29 languages plus Follow System PRIVATE AND LOCAL • Your library stays on your device • No account, login, or cloud sync • No ads, analytics SDKs, or tracking • Sharing and export happen only when you choose IMPORTANT NOTE QR Scene Wallet is not a live QR scanner, QR code generator, barcode scanner, or link opener. It does not open URLs, WeChat, payment apps, or other third-party apps. It is designed to help you organize and find QR scene photos locally. Requirements: iOS 16.0 or later. Universal app for iPhone and iPad.

A complete electrical engineering calculator suite in your pocket — Ohm's Law, reactance, trace width, and more. No ads, no subscription, no nonsense. Pocket Workbench is a complete electrical engineering calculator suite built for engineers, technicians, students, and hobbyists — the tools you actually reach for at the bench, in the field, or mid-design. No ads. No subscription. No account required. Just the calculators you need, done right. CORE CALCULATORS Ohm's Law solver — instantly solve for voltage, current, resistance, or power from any two known values Voltage divider calculator Reactance & resonance — capacitive reactance, inductive reactance, and LC resonant frequency RC/RL time constants — including capacitor charging voltage over time PCB trace width calculator — IPC-2221 standard, internal/external layers, any copper weight Series/parallel resistor & capacitor combinations Delta (Δ) ↔ Wye (Y) network converter LED series resistor calculator Capacitor stored charge & energy SMD resistor code decoder (3/4-digit and R-notation) dB power ratio, voltage ratio, and dBm ↔ watts converters Skin depth calculator with material presets Battery life estimator COMPONENT SCANNER (bonus feature) Point your camera at a resistor, inductor, or capacitor and Sohm will attempt to read its value automatically — color bands for resistors and inductors, printed codes for capacitors. This feature is actively improving; the calculators above are the reliable core of the app. Built for real work: clean interface, fast input, accurate formulas — nothing you have to dig through menus to find. Whether you're laying out a PCB, sizing a trace, decoding a resistor, or just double-checking Ohm's Law at 2am, Pocket Workbench has it covered.
