FastsApp

FastsApp is a shortcut application that directs numbers not registered in users' contacts to WhatsApp chat. With FastsApp, you can access WhatsApp chat without saving the numbers to your contact list. All you have to do is enter the number you want to talk to on WhatsApp into the program. You can also access the WhatsApp chats of the numbers in your call history within the last month with a single click. For example, when you want to send a location to a number you do not know via WhatsApp, you can switch to the WhatsApp chat screen via FastsApp instead of saving it to your contact list.
