Coffee works differently for everyone — and costs everyone different sleep. Stimly estimates when your caffeine has dropped far enough to stop getting in your way at bedtime. Most caffeine apps just count milligrams. Stimly models how caffeine actually moves through your body — using a science-backed metabolism engine calibrated to your age, weight, sensitivity and habits. YOUR DAY AT A GLANCE • Live caffeine level — a real-time curve of what's active in your system now • Drinking now — log slow sips (yerba mate, big lattes) and watch absorption live • Sleep forecast — see when your body will be ready for quality sleep • Smart advice — gentle nudges when one more espresso would cost you tonight TRACK WITHOUT FRICTION • One-tap logging from your personal drinks library • Barcode scanner for bottled drinks • Daily limit with a clear budget bar (including a lower preset during pregnancy) • Symptom journal — connect how you feel to what you drank • 7-day history of everything you've logged STIMLY PRO — OPTIONAL PAID SUBSCRIPTION Everything above is free. These extras require a Stimly Pro subscription: • Tolerance tracking — see habituation build and fade week to week • Expert mode — brew method and dry mass for precision logging • Extended history — month and 90-day views • 30-day wellness export — a clean PDF of your patterns SUBSCRIPTION DETAILS Stimly Pro is an auto-renewing subscription, available monthly or annually.
