Stegais is an Android app developed by Roman Cinkais that enables hidden communication using steganography. The app allows the user to hide a message in a selected image from their photo library or a taken photo from their camera. The user can then send the image containing the hidden message to another person through email or save it to their photo library. The app also enables the user to reveal the hidden message from the image.

Stegais is a free app that falls under the Utilities & Tools category. The app is user-friendly and easy to navigate. The developer encourages feedback and ideas from users to improve communication. However, it is important to read the instructions provided in the app before use. For more information, visit the developer's website or contact their support team directly.
