Focus Fasting - Fasting tracker built for deep work and mental peak

Hey Product Hunt! 👋 I'm a solo developer and I built Focus Fasting out of personal frustration. Like many indie creators, I started experimenting with intermittent fasting not just for health, but to unlock that legendary "fasted focus" for deep work sessions. However, I noticed my daily cognitive peaks fluctuated wildly. Standard fasting apps only focused on weight loss and countdowns, completely ignoring productivity. I wanted a scientific way to map my fast against my mental clarity. That’s why I built Focus Fasting. It integrates a sleek fasting tracker with a built-in Pomodoro timer and energy logs. The core algorithm automatically calculates your "Golden Focus Window"—the exact hours of your fast when your brain is performing at its absolute peak. Based on early feedback, I’ve already optimized the app to support standard AM/PM time formatting and ensured a 100% ad-free experience with premium UI. 🎁 SPECIAL FOR THE PRODUCT HUNT COMMUNITY: I want to make this app perfect, so I'm giving away FREE Lifetime Premium Promo Codes to anyone who helps me test it! Just drop your honest feedback, thoughts on the UI, or feature ideas in the comments below, and I will personally send you a Premium Promo Code via PM. Can't wait to hear your thoughts and see when your Golden Focus Window is! 🧠🚀
