WhatsApp Aid is a messaging app that allows users to send messages to people who are not on their contact list. This app is ideal for individuals who need to send messages to people they do not know or have not yet added to their contacts.

With WhatsApp Aid, users can simply enter the recipient's phone number and start sending messages. This app eliminates the need to save a new contact in the user's phonebook before being able to send a message, making the process more convenient and efficient.
