    whatsapp web is too slow. i need solving that case. and zapfast is a solution. really fast.

    but i must worry about this third party app. many says whatsapp can deactivated my account if i using third party. but i need fast loaded whatsapp. so i still using zapfast.

    as a designer, the thing i need in whatsapp web is send image file as document. and in zapfast that feature did'nt exist. if i send, the file got compressed like sent image not as document.
