DarkroomFlow - Precision film developing timer & lab assistant.

Hey Product Hunt! 👋 I’m Ravi. By day I design digital products, but my weekends are spent shooting medium format film (Mamiya 645/Pentax 6x7). I love the analog process, but I hated the "lab anxiety." You know the feeling: You’re in a dark room, trying to calculate a 1+25 dilution ratio in your head while checking a thermometer and worrying if you missed an agitation cycle. I was ruining good rolls because of bad math. So I built DarkroomFlow. It’s a digital safety net for your analog workflow. It handles the chemistry calculations, auto-corrects for temperature shifts (because my basement is never exactly 20°C), and gives you haptic cues for agitation so you don't have to stare at your phone. We even built a "Red Mode" interface that is safe for printing days. If you develop at home, I’d love for you to give it a shot (pun intended) and let me know what you think. Happy developing! 🎞️
