The Whatsapp Plus interface is almost identical to the original WhatsApp. Want to show a single tick to the person who sends you a msg? WhatsApp plus has a single tick option, which shows a single tick to the sender, even when the message is received and read.
The developer made some changes in the UI and added some extra functionalities. This means that Whatsapp Plus has its own servers, and all your conversations and msgs are sent through those servers. Whatsapp PLUS is an enhanced and customized unofficial third-party version of the original Whatsapp with Modded Stylesheet files.
