For those interested in managing their online visibility on social platforms, LastSeen by Web-Source Ltd offers a specialized solution. Available for download on Google Play, this utility app focuses on monitoring and controlling the visibility of one's last seen status. The install process is straightforward, and the app itself is free to use, though it does contain advertisements and offers in-app purchases for extended functionality.

Upon opening the app, users are presented with a clean interface that immediately asks for the necessary permissions to access notification data. The core functionality revolves around tracking when specific contacts come online or go offline, presenting this information in a chronological log. During use, I found the real-time updates to be fairly responsive, though the reliance on notification access does mean the phone must be configured correctly for it to work as intended.

In comparing LastSeen with similar apps available on Google Play, such as Online Notifier or Watcher for WhatsApp, it distinguishes itself through a more minimalistic design approach. While competitors often pack their interfaces with numerous analytics and graphs, LastSeen prioritizes straightforwardness. This makes it less overwhelming for someone who simply wants to see recent activity without drowning in data, though users seeking deep statistical insights might find it lacking.

• Notification-based tracking – The app relies on reading device notifications rather than directly interacting with messaging platforms, which means it can work across different apps without violating their terms of service. During use, this approach felt reliable, though it does require granting notification access permission.
• Contact-specific monitoring – Users can set individual tracking for specific people rather than logging all activity. This targeted approach is much more practical than apps that flood the user with every single status change from everyone in their contact list.
• Privacy-focused design – Unlike many competitors that ask for extensive data access, LastSeen only requires notification reading permission. This limited scope provides a sense of security, though it naturally restricts the app from offering features like direct in-app messaging or status reply options.

• Helps avoid awkward social situations by knowing when someone was last active before sending a message
• Provides a simple way to track online patterns without manually checking the app repeatedly
• Works across multiple messaging platforms since it hooks into the notification system rather than individual apps

• Battery consumption is noticeably higher when background tracking is enabled for extended periods
• The free version displays ads that occasionally interrupt the user experience
• Some users may find the notification access requirement a privacy concern despite the app's own privacy claims
