Open in Whatsapp

This app uses whatsapp public api to open a chat with any number you enter.
No contact is created on the device.

An unkown number called you and you want to know if they have whatsapp?
You need to send a message to someone but you don't want to save it as a contact?
You want to start a chat with yourself?
Just open the app and enter the number (with prefix).

This is a tool app: simple and lightweight. No extra features, no extra size, no permissions, no ads...just the open-in-whatsapp feature.
