How to Use Android and iOS Apps on Your PC
If you want to use Android or iOS apps on your PC, there are some simple tricks you can take advantage of. To get started, you need to download an Android emulator such as Bluestacks.
AndroIRC - Free IRC Client for Android
AndroIRC is a free and open source IRC client app that works on all Android devices (even those with low or no memory). It's a pretty decent IRC client, with an expansive feature set, including automatic joining of channels on startup, multiple server connections, proxy and SSL support, file transfers, logging, copy/paste functionality, and even a compact mode to reduce screen usage.
Palaver - IRC on iOS
If you're on an iOS device, and are in the market for an IRC client app, you can't do much better than this one. It's loaded with features, like powerful auto-completion, push notifications, iCloud synchronization, and a healthy array of themes and styles.
XChat Azure - IRC on Mac
XChat Azure is a decently feature laden IRC client application for OS X running computers. It supports a wide range of networks, has robust SSL support, and comes with an array of keyboard shortcuts and other goodies.
AndChat - IRC for Android
AndChat is another popular and feature packed IRC client that works on both Android and iOS devices. The main drawback is that it has a somewhat clunky and outdated UI, but it does support all the usual IRC features and add-ons, plus a lot more. It also includes a compact mode for reducing the amount of space it takes up on your phone's screen, as well as a granular menu that lets you kick, ban, or change privileges.
