TopG is a free Android application developed by UBIGWORLD. It falls under the category of Social & Communication. TopG is designed as a messenger specifically for the gay community, providing a platform for users to connect with each other anonymously.

The main features of TopG include the ability to send messages to other gay users randomly and anonymously. Users can also attach pictures to their messages. Additionally, users have the option to filter messages based on their own preferences, such as same area, similar age, or message quality. TopG ensures that messages are not sent to the same user again.

The application also includes an inbox feature, allowing users to read received messages in real-time. Users can view the profile pictures of the senders as well. TopG offers a megaphone feature where users can post messages that will be displayed to a number of other gay users. Users can also reply to megaphone messages.

To personalize the experience, TopG allows users to set a password, ensuring that the application remains discreet. The application also includes a "Today's TopG" service, which showcases the profile photos of 10 registered gays each day.

TopG provides a report function where users can report others, resulting in limitations on their ability to send new messages. This applies to both general messages and megaphone messages. The application also offers a verification function, allowing users to verify their phone numbers and prevent fake profiles and potential crimes.

With the ability to change themes, users can customize the appearance of TopG to suit their preferences.
