Hey Product Hunt 👋
I'm excited to share Caffy with you today.
The idea came from a simple frustration: most caffeine trackers only tell you how much caffeine you've consumed. They don't tell you what actually matters — how much caffeine is still in your body right now and whether it will affect your sleep tonight.
Caffy uses science-based caffeine half-life models to estimate your real-time caffeine level, sleep readiness, and focus windows based on personal factors such as age, sensitivity, smoking status, pregnancy, and more.
I also wanted to make privacy a priority. Caffy is ad-free, requires no account on first launch, and keeps the experience simple and focused.
I'd love to hear your feedback, feature ideas, and questions. Thanks for checking out Caffy!
