Pocket-EC/PocketEC-App — reverse-engineered prompt

Build me the PocketEC mobile app from this repo. I want an Ionic Android app that runs on a real phone, connects to a Potentiostat, and lets the user set up the connection from a Settings page.

The main flow should be simple. Open the app, go to Settings, scan for a new Potentiostat, enter the required communication values, then use the app to configure and record experiments on the device. Please make the screens clear enough for someone in a lab to understand without guessing what to do next. Add helpful messages when a phone is not connected, a Potentiostat is not found, or required settings are missing.

Keep it compatible with the existing Ionic 3 and Cordova setup in this repository. Make sure the install and Android device run commands work, since the app depends on native plugins and cannot just be tested in a browser. Look up current docs online if you need to.
