Ohm & Ember

Ohm & Ember turns your phone into a focused, offline electronics workbench. Calculate voltage, current, resistance, power, LED resistors, and series or parallel totals without leaving the bench. Decode common four-band resistor colors and save useful results directly into a project. Keep a local parts drawer with quantities, values, storage locations, and low-stock indicators. Plan builds with practical project templates, component checklists, progress stages, and bench notes. Record soldering and test sessions so measurements, observations, and next steps stay attached to the work that produced them. The Bench view brings active builds, low-stock warnings, recent measurements, and quick tools together. Everything is stored on the device and remains useful with no account or connection. Starter projects and components make the app useful immediately, while editing, restocking, completing, and resetting tools let the workspace evolve with every build.
