## What it is
Responsively App is a modified web browser built with Electron that helps developers build responsive websites by previewing them on many devices simultaneously. It mirrors user interactions across all device previews and includes 30+ built-in device profiles, a unified elements inspector, and one-click screenshots.

## Use cases
- preview a website on multiple devices at once
- test responsive layouts without resizing devtools manually
- mirror clicks and scrolls across device previews
- inspect elements across all device sizes with one inspector
- take full-page screenshots of all devices in one click
- save favorite device combinations as preview suites

## When to choose
- you are developing or debugging responsive web designs
- you want side-by-side mobile, tablet, and desktop previews with synced interactions
- you need a free open-source alternative to manual devtools device emulation

## When to avoid
- you need automated cross-browser testing on real devices
- you only need a simple screenshot tool without interactive previews
- you are testing native mobile apps rather than web pages
