The diary records what you saw, when, where and what was on your mind, then shows which numbers actually recur for you, in which situations and at what time of day.

Wire Size & Voltage Drop Calc
Size a cable and check its voltage drop from transparent physical formulas, entirely offline. Calculate voltage drop, the minimum conductor cross-section, the maximum run length, conductor resistance and power losses. Choose IEC cross-sections or AWG and KCMIL, enter current or load power, add power factor, cable reactance, conductor temperature and parallel runs, then compare adjacent sizes and estimate the annual cost of the energy lost in the cable. Fourteen more tools cover Ohm's law, the power triangle, power factor correction, motors, transformers, batteries, neutral current, star and delta, solar strings, cable metal mass and cost, series impedance and load summaries. Every result shows the formula and the assumptions behind it, rounding always goes to the larger conductor, and invalid input returns an explicit error instead of a nonsense number. Save calculations into projects and reopen them with every input restored. The app reproduces no ampacity table from any wiring code and never recommends a circuit breaker rating. Works fully offline. Free and ad-supported.

Every formula is shown on screen. Works fully offline, 15+ languages. Free and ad-supported.

Everything works with no signal at all. 41 languages. Not a scan tool: it does not connect to the truck and does not clear anything. Free and ad-supported.
