Each one does a single job your crew already knows by heart, then hands back the finished, documented result. No app store. No new software to learn. Open it in your browser, add it to your home screen, and it works like any other app.
Two are live now; the rest of the workshop is on the way. Every one is built on thirty years in high-voltage and field operations.
Open the app on your phone, then add it to your home screen. You'll get its icon, and it opens full-screen like a normal app.
