WhatsMySelf is a free Android app developed by Nono Bit Sistemas that allows users to create a chat with themselves on WhatsApp or start a conversation with an unregistered number without having to save it as a contact. This app provides several benefits for WhatsApp users.

By creating a chat with yourself, you can easily save important information, such as a grocery list, memes, or gifs to share later. This feature is especially useful for those who use the desktop version of WhatsApp, as it allows for easy transfer of documents, photos, and videos between devices. Additionally, you can use this chat to test new WhatsApp features or external shares before sending them to friends or groups.

The app also enables users to start a conversation with a number that is not registered in their contacts. This feature is handy for one-time communications, such as ordering from multiple budgets, or for those who are in another city and need to order a pizza. By not having to save the number, users can keep their contact list clean and organized. Overall, WhatsMySelf is a useful tool for anyone who wants to streamline their WhatsApp experience.
