LastSeen tackles a simple but persistent problem: keeping track of when you last checked in on your apps, files, or even physical items. After seeing how often I'd open a folder only to realize I'd already reviewed it, or lose track of whether I'd responded to a certain app notification, I knew I needed something to track these moments without manual logging. That's exactly where LastSeen steps in.

The app essentially creates a timeline for anything you mark as important. You can assign timestamps to apps, documents, or custom entries, and LastSeen automatically notes the last time you viewed or interacted with them. For the core functionality, it works reliably - the automatic timestamping is accurate, and the manual override option gives you flexibility when the app doesn't catch everything. Beyond just tracking, it offers sorting views by date, category, or priority, which helps when you're managing multiple items at once.

I found myself using it mostly for work files and communication apps. It solved the nagging feeling of wondering, "Did I already check that?" by giving me a clear record. The app doesn't overwhelm you with features, but it does what it sets out to do without much fuss. I'd recommend LastSeen to anyone who juggles multiple projects or tools daily - especially remote workers, students managing coursework, or people trying to reduce digital clutter by knowing exactly what they've already looked at. It's most useful when you have a moderate number of items to track; with too few, you can just remember them, but it shines when the volume starts getting hard to keep straight in your head.

• 📅 Automatic Timestamp Tracking – The app records the last time you viewed an app or file without you having to tap anything. It's surprisingly accurate and removes the mental load of remembering when you last checked something.
• 📅 Manual Override Option – If the automatic tracking misses something or you want to log a physical object like a document, you can manually set the timestamp. This flexibility makes it useful beyond just digital items.
• 📅 Custom Categories and Tags – You can organize your tracked items into groups like "Work," "Personal," or "Must Review." This turned my messy list into something genuinely useful for daily prioritization.
• 📅 Sort and Filter Views – Being able to view items by "Last Seen Today" or "Oldest First" helps me spot what's been neglected. The filter tools are simple but effective, especially when the list grows beyond a dozen entries.

• 🏆 Zero Setup Required – The app works almost immediately after installation. There's no complex configuration, which is refreshing in a world of bloated onboarding processes.
• 🏆 Lightweight Performance – It barely uses resources. I've had it running alongside heavy work apps without any slowdown or battery drain, which is more than I can say for many utility apps.
• 🏆 Clean, Minimal Interface – The design is straightforward and clutter-free. You won't spend time figuring out where everything is, and that matters when the whole point is saving time.

• 🔴 Limited Cross-Platform Sync – LastSeen doesn't sync well across multiple devices. If you use both a phone and tablet, your tracked items won't always match up, which undermines the whole purpose.
• 🔴 No Notification Reminders – You can't set alerts to remind you when something hasn't been looked at in a while. For a tracking app, this feels like a missed opportunity to be proactive rather than just reactive.
• 🔴 Occasional Lag with Manual Edits – When I manually changed a timestamp, the app sometimes took a few seconds to update the view. It's not a dealbreaker, but it breaks the flow when you're making multiple adjustments quickly.
