BUILT FOR REAL JOB SITES
No signal in the generator room? No problem. Everything works offline. Search by the number on the controller, by brand, or just describe the symptom.
PRO PLAN
The Pro plan adds the AI assistant and the Job Builder: drag equipment onto a canvas, pull feeders, and it sizes breakers, wire and cable - then produces single-line diagrams and material order sheets so quotes go out the same day. Job Builder runs on your Mac or PC through a secure emailed link - no download, no password.
PRICING
7-day free trial - full app, nothing to set up. Then Basic $4.99/month (all codes, sensor tests, guides and calculators) or Pro $7.99/month (everything plus AI assistant and Job Builder). Cancel anytime in Google Play.
