I built ZonePlan (zoneplan.net) as a free worldwide meeting planner. One query just crossed 258 Google impressions in 28 days.
The problem: worldwide meetings spanning Asia, Europe, and the Americas have conflicting DST transitions. ZonePlan shows a visual overlap grid of 24 hours across all selected time zones so you pick the one slot that works for everyone.

I d love to introduce YouArt AI a tool designed to simplify visual content creation and eliminate prompt engineering frustration.
Have you ever tried generating a set of images with AI, only to give up because keeping character consistency or getting the exact style took hours of prompt tweaking?
The idea for YouArt AI came from working with creators and non-designers who loved the potential of AI tools, but found prompt syntax way too complex and time-consuming. We wanted to build something where anyone could create consistent, high-quality visuals using intuitive UI workflows and AI agents instead of writing massive blocks of text.
I've taught guitar for years. The kids who stick with it aren't the ones who learn theory first they're the ones who get handed a song they already love in week one. Every app in my category does the opposite. Scales, levels, streaks, a progress bar. Very good at making you feel like you're learning. Not very good at making you play a song. So I'm building the opposite: no lessons, no levels, no streaks. Upload a song, get the chords, play it. Genuinely open to being wrong about this. Anyone here learned an instrument properly through structured lessons and think I'm underrating them?
I wanted to share a side project I've been working on to solve my own "algorithm fatigue." I realized music apps tend to loop the same popular tracks, making it almost impossible to discover obscure, low-playcount hidden gems from around the world.
So, I built PlayVoid (https://playvoid.live)
It s a completely "blind" music discovery SPA (Single Page Application) with a TikTok-style feed for audio.
We're all builders here, but just because we can now ship incredibly fast, doesn't mean we're necessarily shipping the right thing.
How are people here validating product ideas, writing PRDs/specs for coding agents, making sure they fit in the context of their codebase and product, finding ways to get their ideas through to production much faster, etc?
My shameless plug is that we're launching Rezonant today, which helps teams do exactly that: https://www.producthunt.com/prod...
Would love to hear your comments and thoughts on it, we're building this for you guys.
Don t accidentally cross a tax/visa threshold while traveling
Hi everyone! I joined the small Flamingo Compliance team less than 2 weeks ago and we re building an iOS app that helps frequent travelers and global teams track days-in-country and generate an audit-ready travel record. We don t give legal advice, we help you keep clean evidence and visibility.
I'm Arun, an independent consultant and the builder behind Verity.
I built this because I kept seeing the same problem across every B2B clients I worked with: great businesses with excellent content on their websites and within documents. Even a fancy search feature couldn't help users find a lot of the information.
