A must have APP

This app has saved me real time on the job. The guided fault trees walk you straight to the fix for the most common problems — motors, breakers, VFDs, PLC faults — no digging through manuals. The searchable fault code database (PowerFlex, Fanuc, Siemens, Yaskawa) plus the electrical reference tools like NEC wire sizing and the voltage drop calculator make it the one app I reach for first. Fast, works offline, no fluff. Worth every penny.

What's new in 1.1.0 • Reorder your tabs — press and hold a category on Reference, Tools, or NFPA 70E and drag your most-used sections to the front. Your order is saved. • Save fault codes — tap the star to pin codes, and filter to your saved list. • More drives — added fault codes for ABB (ACS), Schneider Electric Altivar, Danfoss VLT, and Mitsubishi FR. • Rate the app — a quick prompt after you've used the troubleshooter a few times. • Fixes & polish — corrected a Panel/Distribution diagnostic path, the safety disclaimer now appears only on first launch, and cleaned up tab labels and buttons.
