WhatsCloud is a free Android app developed by Oguzhan Yigit, designed to help you analyze your WhatsApp chat history with just one click. With this app, you can get statistical data about your chats, such as the number of messages sent, which words are used the most, and who are the most active participants. The app provides graphical representations of the data using charts and graphs, which are interactive with zoom and pan features. Additionally, WhatsCloud allows you to analyze chats with each participant, view the most active days and weekdays, and see the average message sending frequency.

One of the most impressive features of WhatsCloud is that it works even though WhatsApp does not provide a public API. The app analyzes the user-generated export of chat history, which is in a *.txt file format, and gives various graphical representations of the analyzed statistical data. If you encounter any bugs or have any feature requests, you can visit the project's main page on GitHub. In conclusion, if you want to learn more about your WhatsApp chats and get statistical data about them, WhatsCloud is definitely worth trying out.
