Bumblebee is a free Android app developed by backslash, categorized under Utilities & Tools. Its main feature is the ability to hide secret messages in images using steganography. This means that the information is stored within the image and cannot be retrieved or stored by social apps, ensuring that your text remains a secret.

To reveal the secret text, users can open the encrypted image in Bumblebee and click on the 'Pin' icon. However, it is important to note that sharing images via some apps, such as chat apps, may cause the images to be compressed, resulting in the loss of the secret text. Overall, Bumblebee is a useful app for those who value privacy and need to send sensitive or confidential messages.
