WhatsApp Opener - Open Whats app with phone number

Have you ever tried to send a simple message or a file to someone on WhatsApp and didn't wanted to add them to your contact list?
Do you have so many temporary contacts just because you wanted to send them a message once in WhatsApp?
With this app you can start a chat with any number who registered on WhatsApp without saving them in your contact list.
This is a benefit for your privacy as well. Since you don't save the number in your contact list, they can't view your profile picture (based on your WhatsApp privacy settings). Cool ha? You're welcome :)
You can have a list of recently entered numbers so you don't have to enter them again.
This app stores numbers on your device only and never send any of the numbers you entered to the internet.

Happy WhatsApping to strangers.
