See your
caffeine fade.

Cafade turns coffee, tea, soda, energy drinks, and custom entries into a calm estimate of what remains in your day.

Coming to iPhone. Estimates are for personal tracking, not medical advice.

A caffeine decay curve fading across a 24-hour timeline.
01 / THE IDEA

One small log.
A clearer day.

You do not need another dashboard. You need to know what that last drink might still be doing at bedtime.

01

Log what you drank

Choose a familiar US drink, adjust the serving, or enter the caffeine amount from a label. Coffee is not the only thing that counts.

02

Watch the line move

Cafade estimates the caffeine remaining from each entry using a simple half-life model. The curve updates as your day changes.

03

Make room for sleep

See the estimated amount at your chosen bedtime and compare the pattern over longer periods with Cafade Pro.

02 / BUILT FOR REAL LIFE

Useful when the label is missing.

Values vary by product, size, recipe, and preparation. Cafade keeps the estimate visible, lets you correct it, and keeps your entries on your device.

LOCAL FIRST

No account required

Your log works without an account. HealthKit is optional, and the first release writes only the caffeine entries you choose to save.

YOUR UNITS

US sizes, your way

Start with a practical US catalog, from a small hot coffee to a Venti iced drink. Switch between US customary and metric units.

LESS NOISE

A calmer view of caffeine

No guilt score, no medical promise, and no pressure to quit. Just a more legible view of what you already drank.

Know what you drank.
See what remains.

Cafade is being built for iPhone, with a quiet interface and a useful answer when you need it.
