Hey Product Hunt! I built Circadia because every jet lag guide I found online contradicted the next one, and none cited actual sources. So I went and read the research myself (phase-response curves to light and exercise, melatonin dosing studies) and built a tool that applies it to your actual flight instead of generic advice. Would love your feedback, especially if you're a frequent long-haul flyer — what would make this genuinely useful for you?
