Zap Messenger is a communication application developed by ZapLab for Android devices. The app allows you to send messages and make calls to your friends and family using your phone's internet connection, whether it's 4G/3G/2G/EDGE or Wi-Fi, without any additional charges. Zap Messenger also allows you to send and receive multimedia messages, including photos, videos, documents, and voice messages.

One of the notable features of Zap Messenger is its ability to make free voice and video calls to friends and relatives, even if they are in another country. The app uses your phone's internet connection and not the voice minutes included in your phone plan. Additionally, you can create group chats to stay connected with your contacts easily. Zap Messenger also offers features such as sharing your location, exchanging contacts, setting custom wallpapers, and notification sounds, and more, with new features regularly added.

Zap Messenger integrates with your phone's address book, making it easy to connect with your contacts who have installed the app. It also saves your recent messages and delivers them when you're back online, ensuring you never miss a message. The app is entirely free to use, with no subscription fees or hidden charges. If you have any questions or suggestions, you can contact the Zap team via email or follow them on Facebook.
