EEPocketworkbench vs RefoMeasure

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.

How many metres of wallpaper, packs of flooring, or plasterboards should you buy? RefoMeasure turns room dimensions and the specifications printed on your chosen products into practical material estimates. It is designed for DIY projects and small renovations, from measuring a room to preparing a shopping list. FOUR MATERIAL CALCULATORS • Wallpaper: calculate strip counts and required roll length • Flooring: calculate packs from work area, waste allowance, and coverage per pack • Plasterboard: calculate boards from surface and board dimensions • Sheet vinyl: calculate purchase length from room direction, roll width, and trim allowance A CLEAR PATH TO YOUR SHOPPING LIST 1. Create a project and add a room 2. Check the size and packaging details of the product you plan to buy 3. Calculate the required quantity and add it to your shopping list 4. Combine rooms or projects and review them in a PDF KEY FEATURES • Multiple projects and rooms • Reusable product specifications • Calculation history and calculation details • Duplicate-purchase confirmation • Optional unit prices and estimated material cost • PDF and CSV shopping-list export • Local backup and restore • Japanese and English interface PRIVATE BY DESIGN No account is required. The app contains no advertising or analytics. Project and calculation data stays on your device unless you choose to export or share a file. ONE-TIME PURCHASE One App Store purchase unlocks the complete app. There are no in-app purchases or subscriptions. PLEASE NOTE Calculated quantities are estimates. Check the actual product dimensions, package coverage, pattern matching, installation method, site conditions, taxes, delivery costs, and labour before purchasing. RefoMeasure does not provide installation, safety, structural, or regulatory advice. The app interface is available in Japanese and English. Exported PDF/CSV reports and launch artwork are currently in Japanese. email：CnhookWuaizhen@gmail.com
