CapLab

CapLab is a demonstration app for a set of open Capacitor plugins that read

Android device state — network, screen, battery, and more — without

requesting any special permissions.

Each plugin in this demo is installed as a real npm package

(@tojestproste/caplab-*), proving the plugins work as standalone,

independently publishable modules rather than app-specific code.

WHAT'S INSIDE

• Network — WiFi/cellular transport, link speed, DNS, signal strength

• Screen — resolution, density, refresh rate, system bar heights, font scale

• Battery — level, charging status, temperature, health

• Device — model, codename, RAM, storage, security patch level

• Locale — language, timezone, dark mode, date/number formatting

• Sensors — full list of physical sensors available on the device

• Audio — volume levels per stream, ringer mode, connected output devices

• Power state — battery optimization status, Doze mode, screen interactivity

• Connectivity — Bluetooth and NFC state

• DevMode — developer options, USB debugging, build info

Tap any plugin to see a live summary plus the full raw JSON response

returned by the plugin.

WHO THIS IS FOR

Android/Capacitor developers who want to see exactly what each plugin

returns before adding it to their own project, or who want a working

reference implementation to build from.

This is a technical demo app, not a consumer utility — no ads, no

analytics, no data leaves the device.
