IOS App for Whatsapp Online Tracking ans Stats

According to this answer for iPhone developers on WhatsApp FAQ; WhatsApp provides two ways for your iPhone app to interact with WhatsApp: 1-)Through a custom URL scheme 2-)Through the iOS Document Interaction API If your application would like to open/Check online status a WhatsApp Chat with a specific contact, you can use our custom URL scheme to do so. Along with it, there is a mobile tool WhatsApp-Tracker that checks the last time online whether the user has enabled or disabled the last seen time. Also, it allows tracking when the user is online or offline, whether the user has the "last seen" hidden or not. For users who have active the last time online, it is not very useful, as anyone can see when was the last time he was online. But this tool also lets you know when was the last time of a user with 'last online' hidden. There are currently two ways to display the user's last seen time, by screen or remotely. Remotely will send you a log of the user you are tracking After completed setup WhatsApp-Tracker: We will configure the Push Notification in a custom way. So it can be fired instantly when the tracked number comes online As WhatsApp-Tracker only can provide the last time when user goes online, so every time such a way we need to store that log into an array perspective to the user. The reason for this script: More than anything to show that there is no privacy and can automate monitoring of any user. Honestly, there are clients with better privacy.
