PRECISIONIN YOURPOCKET.
Purpose-built measurement tools for electrical engineers. Voltage, current, power — field-accurate, instantly.
EVERY TOOL YOU REACH FOR.
Six precision instruments. All in your pocket.
Voltage Calculator
Instant voltage drop across any conductor length. Stays accurate at 0.1% tolerance.
Current & Load Analysis
Calculate load current, phase balance, and demand factor for any circuit configuration.
Power Factor Meter
Measure apparent, real, and reactive power. Flag PF issues before they cost you.
Unit Converter
60+ electrical units: kW↔HP, V↔mV, Ω↔kΩ, Hz↔rad/s — all field-calibrated.
Fault Current Calculator
Compute available fault current at any point in the system. Meets NEC + IEC standards.
Offline Mode
Full functionality with no signal. Perfect for substations, underground vaults, and remote sites.
SEE IT IN ACTION.
THREE STEPS TO THE ANSWER.
Open the App
Launch All from your phone. No login, no setup — tools are ready instantly.

Read the Answer
Get field-accurate results in under a second. Exportable for reports.
Less than a coffee. More accurate than desktop software.
“I used to pull up desktop software every time I needed a voltage drop calc in the field. All does it in 10 seconds on my phone. It's become my most-used work tool.”
“The fault current calculator alone is worth it. Accurate to NEC standards, works offline in the substation. Hasn't missed once.”
“Clean interface, fast results. I wish the export format had more options, but the calculations are spot-on every time.”
