Show HN: Intermittent Fasting Calculator – Plan Meals and Fasting Times

https://intermittentfastingcalculator.org/
2•MatthewTKD•5h ago
Hi HN,

I just launched Intermittent Fasting Calculator, a free, no‑signup web tool to plan your next meal and fasting window.

Pick from popular methods (16:8, 14:10, 18:6, 20:4, OMAD) or set a custom fasting window (1–23 hrs), enter your last meal or desired next‑meal time, and get an instant, color‑coded 24‑hour timeline.

Export results as text, image, or PDF. Works on mobile and desktop, with built‑in guidance on fasting methods and safety.

I built this to simplify my own fasting schedule planning—no more mental math or clunky apps.

I’d love to hear your thoughts on the UI, features, or anything you’d add. Thanks!
