Hey Product Hunt! 👋 I built Bookstacks because I kept forgetting which books I owned and buying duplicates. I wanted something dead simple — scan a barcode, done. The whole app is built with Flutter + Riverpod, stores everything locally with Hive (no account needed), and fetches metadata from OpenBD, Japan's open book data API. Would love any feedback on the UX or missing features. Happy to...

Hey Product Hunt! 👋 I built DoneLog because I kept second-guessing myself – "Did I take my meds today? Did I lock the door?" The key insight: most task apps are for *planning*, but I needed something for *confirming*. So I made it as frictionless as possible – one tap, done, resets tomorrow automatically. Would love your feedback! What routines would you track with it?

Hey Product Hunt! 👋 Built this because I wanted to actually see the long-term impact of my financial decisions — not just a static spreadsheet, but an interactive simulation I could tweak on my phone. Would love your feedback!

👋 Hi Product Hunt! I'm the maker of ggc, a Git CLI tool built in Go. I made ggc because I often wanted something faster and more interactive than the usual Git CLI. Sometimes I need fuzzy search, sometimes I just want to run addcommitpush in one go. So I built both modes — interactive and traditional CLI — into one tool. ggc supports: An interactive UI for common Git tasks Git-compatible config...
