This application is 100% working app .. it use the Last seen Api to track last seen for contacts and it use the last uploaded data in WtsApp.
Last seenTracker is an app that obtain the WtsApp last seen time and date according to the Last seen Api.
It's a tool that allows to track 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.
Use it now maybe later WtsApp will change the Api and stopped
