Improved WhatsApp experience on a Windows PC with customizable themes and easy access to your account by scanning a QR code.

Although WhatsApp Web has received plenty of praise, it does come with its fair share of limitations that may impede some users. However, fear not, as there are many unofficial clients that can solve these issues in unique and innovative ways. One of these clients is Altus, an Electron-based desktop app for WhatsApp that's compatible with Windows.

When you download Altus, you'll be able to access a host of cool features that will enhance your experience with the app. Firstly, you'll notice that Altus looks sleek and modern, and it comes with support for multiple accounts thanks to its tab bar. You'll be able to run multiple instances of WhatsApp from a single window, each with a unique name and personalized theme.

Altus has a settings section that allows users to customize various options like disabling the exit prompt or hiding or showing the tray icon. But the real kicker is the Theme menu, which lets you choose between various pre-existing themes or create a custom one with the Theme Customizer.

In this menu, you can change the background and text colors, the accent and shadow colors, and even the emoji opacity levels. The result is an entirely customized version of WhatsApp that's tailored to your preferences.

All in all, Altus is the ultimate tool for users seeking a more efficient way of running multiple instances of WhatsApp on their desktops. Its full customizability and sleek design make it stand out from the crowd, and we're excited to see what the future holds for this innovative app.
