YoWA is an unofficial WhatsApp mod that lets you personalize this popular instant messaging service with many more options than the official client. YoWA offers various themes to choose from, allowing you to customize all your conversations and give each one a unique background. You'll also have access to a plethora of emoticons, the ability to send full-size images and videos, and the option to send multiple images at once (up to 700 simultaneously). This app also lets you hide contact names and increase the font size.
Beyond all the aesthetic improvements and new features, YoWA functions almost identically to a standard WhatsApp version. You can call any of your contacts, send text messages, voice messages, images, videos, and more. You could easily switch from the basic WhatsApp client to this enhanced version and start texting your friends almost immediately.
