Hey Product Hunt! 👋 Thanks for checking out Audiobook Speed Calculator! I'm Audiobook, and I built this because I was tired of doing mental math every time I started a new audiobook. **Quick backstory:** I listen to audiobooks during my commute, usually at 1.5x speed. But every time I saw "12 hours," I'd think "okay, so that's... 8 hours? No wait..." After the 100th time, I just built this tool. **What makes it different:** ✓ Instant - no waiting, no loading ✓ Simple - one purpose, done well ✓ Free - genuinely no monetization (yet?) ✓ No BS - no signup, no email, just use it **I'd love to hear:** - What features would make this more useful? - What other audiobook tools do you wish existed? - Any bugs or issues you find? Thanks for your time! Let me know what you think 🙏 P.S. - Yes, it works on mobile! That was actually the main use case since I usually check audiobook lengths on my phone.
