Hey Product Hunt 👋 I'm Caki, a solo dev (7+ years iOS/React Native) - Fill The Hour is the first product I've built and shipped fully on my own, alongside client work. The problem: appointment-based businesses (therapists, chiropractors, dentists, med spas...) lose real revenue every time a client cancels last-minute, because there's rarely a fast way to fill that slot before it's gone for good. Fill The Hour sits on top of whatever booking calendar you already use - no migration, no switching systems. When a cancellation happens, it automatically texts people on your waitlist to offer up the open slot via SMS. 14-day free trial, no card required. Would genuinely love your feedback - especially if you run or work with an appointment-based business. What's your current process when someone cancels last-minute? Trying to make sure I'm solving this the right way. Thanks for checking it out! 🙏
