Photonoter vs EEPocketworkbench

Photonoter helps you capture quick notes exactly when you need them: with a photo, an image from your library, an audio recording, or a scanned barcode. Create entries in just a few taps, add notes, assign a category, set a date, and optionally schedule a reminder. Your entries are organized by date, easy to edit later, and can include useful details such as documents, receipts, warranties, recipes, or anything else you want to remember. Features: - Take a photo or choose one from your photo library - Record and play back audio notes - Scan common barcodes and QR codes - Add text notes, categories, dates, and reminders - View entries grouped by day - Edit saved entries whenever needed - Zoom into saved images - Store data in iCloud when available, with local storage as fallback - Manually sync your entries Photonoter is made for everyday moments: receipts, product codes, documents, ideas, appointments, shopping reminders, warranty notes, and all the small things you do not want to lose.

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.
