of regular coffee drinkers experience withdrawal when they stop.

Quit caffeine without the Wednesday headache.
StopCoffee designs a personal tapering schedule from the drinks you actually order — the same gradual-reduction protocol that achieves 75–84% sustained cessation in clinical trials.

The problem
Quitting caffeine is harder than coffee culture admits.
Caffeine withdrawal is a recognized clinical condition. Most people who try to quit do it the same way: stop on a Monday, suffer through a headache, give up by Wednesday. The research has known the better path for thirty years.
62%
who try to quit can't sustain it for 30 days unaided.

How it works
A four-week protocol the science already agreed on.
- 01
Assess
Log a typical day. The app reads from a database of 50+ beverages, so a 16oz cold brew counts for what it actually is — not what the menu says.
- 02
Taper
Get a personalized stepdown across 3–8 weeks. Reductions follow the 25% / 50% / 75% protocol used in cessation trials, paced to your tolerance.
- 03
Track
Quick daily check-ins. Symptom intensity, sleep, mood. The app spots patterns and adjusts your next step if your week was rough.
- 04
Free
Most users hit zero in five weeks. From there, an optional maintenance mode keeps you under a chosen ceiling — for sleep, anxiety, or pregnancy.
The science
We've read the studies so you don't have to.
Every recommendation in StopCoffee maps to a peer-reviewed source — gradual tapering protocols (Juliano & Griffiths, 2004), the DSM-5 withdrawal criteria, the IOM safety thresholds. No blog hearsay, no influencer wellness, no fasting bro-science.

In the app
Built like a journal, not a dashboard.
Intake tracker
One tap to log. The app remembers your usual order; the database handles the rest. No food-diary fatigue.
Symptom log
Two-second daily check-ins. Your taper adapts when a week was rough.
Beverage database
50+ drinks with verified caffeine content. No guessing what's in your matcha.
Education that earns its place
Short reads tied to where you are. "Why day 3 feels worse than day 1" lands on day 3, not in your inbox the day you signed up.
From people who finally finished the taper.
I'd quit and re-quit caffeine for ten years. The headache always won. Stretching the reduction over five weeks meant I barely noticed I was tapering.
The symptom tracker is the part I didn't know I needed. Seeing day 3 was the worst — and that day 5 would be easier — kept me going.
I'm on the 'maintenance' setting now. 100mg/day, no anxiety spikes, sleeping again. I can have a coffee with my parents at brunch without paying for it at 2am.
-
Will I get a withdrawal headache?
If you taper at the pace StopCoffee recommends, most users avoid the classic crash headache entirely. Cold-turkey produces it in roughly half of regular drinkers (Juliano & Griffiths, 2004); gradual reduction reduces it dramatically.
-
How long does caffeine withdrawal last?
Symptoms typically begin 12–24 hours after last intake, peak around 48–72 hours, and resolve within 7–10 days. The app's timeline view shows where you are in that arc in real time.
-
Can I keep one cup a day?
Yes. Most users set a target — 100mg, 200mg, or zero — and the taper meets it. There's a maintenance mode that simply keeps your daily intake under a chosen ceiling.
-
Is StopCoffee safe during pregnancy?
Caffeine reduction is generally encouraged during pregnancy. The app supports a clinician-set ceiling (e.g. 200mg/day per ACOG guidance), but is not a substitute for medical advice.
-
Does it work for tea, energy drinks, soda?
Yes. The 50+ beverage database covers everything from matcha to pre-workout. Caffeine is caffeine — the source matters less than the milligrams.
-
What does it cost?
A free tier covers tracking and the core taper. Premium unlocks advanced analytics, multiple plan modes, and exports — the first week is always free.
