Hi Product Hunt! 👋 I’m Serdar, a solo developer. I’ve spent the last decade building enterprise systems and mobile apps, and lately, I’ve been focusing on the "niche app" trend—building high-quality tools for very specific problems. I built Whos because most debt or item trackers out there are either bloated with unnecessary features or haven't been updated since 2010. I wanted a modern, minimalist solution for one simple question: "Who has my stuff?" The app has already hit 10+ Pro subscribers during its soft launch, which proved to me that people actually want a dedicated, clean UI for this instead of just using a notes app. Key features I’m excited about: The Blacklist: My favorite feature. It’s a private way to flag people you shouldn't lend to again—kind of a "fool me once" insurance. Photo Documentation: Attach a photo to any record so there’s no "I never had that" argument later. Speed: Add a record, set a reminder, and you're done in seconds. I’m building this in public and actively adding features based on user flow. I’d love to get your honest feedback on the UI or the concept. What’s the one thing that usually annoys you about tracking apps? I’ll be here all day to answer your technical questions!
