WhatsApp has a function that removes the last seen, making it impossible to know when the person last entered the application. For this, there is an application responsible for monitoring a certain contact and always showing when the person goes online and how long they remained online.
O aplicativo é bem simples de ser usado, basta você digitar o número de quem você quer monitorar e ele já começa automaticamente, notificando sempre quando o contato ficar online, tornando-se um aplicativo extremamente útil.
In the video below you can see how the application works:
