Caffeine Insights

Time caffeine,
sleep better.

Caffeinly models how caffeine actually moves through your body, then tells you your personal cut-off time — tonight. Not a diary. Not a quit-app. A coach that adapts to your goal.

Your caffeine today

Sleep-safe at 1:30 PM

Caffeine drops below your limit

cutoff 7am 10am 1:30pm 11pm

Built around what you're fixing

Sleep better

See tonight's sleep impact before you sip — and your exact sleep-safe cutoff time.

Beat the afternoon crash

Forecast the dip before it hits, and time your next cup around it instead of after it.

Calm the jitters & anxiety

Stay under your own overdrive line — a personal limit, not a generic warning.

Cut back, gently

A week-by-week taper plan, minus the withdrawal headache of quitting cold turkey.

Sharpen focus

Line your caffeine up with when you actually need to perform — not just whenever.

What's your caffeine type?

Find out — then watch it play out on your own curve.

A 1-minute quiz gets your type. Add a few real doses and see your sleep-safe cutoff, crash risk, and jitter zone update live — no sign-up required.
