ElectroCalc Pro vs Inductor Design Pro

ElectroCalc Pro is the essential utility for electronics engineers and hobbyists. Simplify your daily circuit calculations with this powerful tool. [Key Features] 1. Basic Electronics - LED Resistor Calculator - Voltage Divider Calculator (Vin, R1, R2, Vout) - LM317 Voltage Regulator Calculator 2. Power & Cables - Ohm's Law Calculator (Voltage, Current, Resistance, Power) - AWG (American Wire Gauge) Table & Conversion 3. Battery Tools - Battery Runtime Calculator - Battery Configuration Calculator (Series / Parallel) 4. PCB Tools - PCB Trace Width & Resistance Calculations

Inductor Design Pro is a secure, offline-first power inductor design tool for power electronics engineers and magnetic component design workflows. Core capabilities: AP-method and LI²-method core selection, joint core-and-winding iteration, Pareto non-dominated filtering with DQS five-dimension scoring (loss, core volume, thermal margin, manufacturability, risk), and automatic multi-candidate comparison. Supports custom material / core / bobbin databases merged with the built-in library. Peak flux density B_max is optional — leave blank to auto-determine from material and operating temperature; if set manually, use values appropriate to the material family to avoid excluding viable cores too early. Topologies: Buck, Boost, Forward (output filter inductor only, not the transformer), and Interleaved Buck (multi-phase, one inductor per phase), with CCM / DCM / BCM modes and full co-evaluation of core, material, air gap, temperature rise, and losses. Parameter sweep: frequency sweep and ripple-ratio / DCM sweep charts visualize how inductance and core size vary with key parameters, helping you trade off switching frequency against core size. Workflow: three-step closed loop (Specifications & Constraints → Core & Winding Selection → Summary & Report), with PDF report and JSON design-file export. Built-in core and wire database included. Privacy & data: core design runs locally; design data stays on your device and is never uploaded to the developer’s servers. Subscription and restore purchases require a network connection. Subscription: Inductor Design Pro Annual Subscription, 1-year term, auto-renews at expiry, $29.99/year (Mainland China ¥198/year; other regions as shown in the App Store). New users get a 14-day full-feature free trial — see the Subscription tab (3rd tab in the app). Manage or cancel anytime in Settings → Apple ID → Subscriptions; no refund for the current period. Privacy commitment: no data collection, no account system.
