WaitLink — Live Walk - Live Walk-in Wait Time Tracker

WaitLink is a real-time wait time tracker designed for walk-in businesses like barbershops, salons, and clinics. Customers scan a window poster QR code to see live queue updates, estimated wait times, and their spot in line directly from their phone—no app download required. Front desks manage check-ins effortlessly with one-click calls, while business owners get custom branding, window posters, and daily turnaround analytics. Eliminate crowding and boost customer trust with zero hassle.

🚀 SpinWheelGo is live — Turn any document into an interactive live quiz & spin wheel in 10 seconds

Hey Product Hunt!

We all love interactive tools for meetings, presentations, and classrooms but nobody loves:

Forcing participants to download an app or sign up

I'm launching a free, no-signup AI engagement tool next week — what would you build first?

Hi PH

After watching teachers, parents, and event hosts struggle with engagement tools that demand sign-ups, paywall the AI features, and quietly store learner data, I've spent the last few months building SpinWheelGo a free, no-signup AI tool that turns any topic or PDF into a spin wheel, live quiz, audience survey, or flashcard set in under 10 seconds.

We launch on Product Hunt on 5/30/2026 and I'd love this community's brain on three things before we go live:

  1. If you've ever used Kahoot, Quizizz/Wayground, Mentimeter, or Slido what frustrated you most?

  2. We've planned a 6-month free-only window before introducing pro tiers. What single feature would make you actually pay for "pro" later?

  3. Teachers, trainers, event hosts, HR folks what's the engagement headache nobody has solved yet?

We're a small team listening hard before launch every reply here genuinely shapes the v2 roadmap.

(Sneak peek if curious: https://www.spinwheelgo.com yes it's already live, no signup needed.)
