Caffeine Tracker: Sleep Cutoff

Understand your caffeine timing instead of only counting cups.

Caffeine Tracker helps you log caffeinated drinks, estimate how much caffeine may still remain in your system, and plan your latest caffeine cutoff before bedtime.

Log coffee, tea, cola, and other caffeinated drinks, then follow a simple modelled caffeine curve throughout the day.

TRACK YOUR CAFFEINE

Quickly build your daily caffeine log with saved drinks, quick-add options, or custom entries.

• Log drinks with caffeine amounts and times
• Save commonly used drinks for faster tracking
• Add custom drinks when needed
• See your total caffeine logged today

SEE WHAT MAY STILL BE ACTIVE

Your dashboard gives you a clear estimate of your caffeine timing based on the drinks you record.

• Estimated caffeine remaining right now
• Estimated caffeine remaining at bedtime
• Visual caffeine curve across the day
• Time since your last caffeine

The estimates use a modelled caffeine half-life and are designed to give you useful planning context.

FIND YOUR SLEEP CUTOFF TIME

Set your bedtime and see a suggested caffeine cutoff time.

Instead of wondering whether an afternoon coffee may still be affecting your evening, use the cutoff estimate to make a more informed choice about your next drink.

REVIEW YOUR CAFFEINE HISTORY

Look back at recent days and understand the habits behind your caffeine intake.

• Compare daily caffeine totals
• Review individual drinks from previous days
• Follow your estimated caffeine curve for each day
• See your weekly caffeine pattern

DISCOVER USEFUL PATTERNS

Insights turn your caffeine log into simple trends without complicated scores or medical labels.

Review:

• Average daily caffeine
• Average last-caffeine time
• Days when caffeine was logged after your cutoff
• Your most frequently logged drink

BUILD A BETTER CAFFEINE ROUTINE

Whether you are tracking coffee, reducing late caffeine, or simply trying to understand your daily intake, Caffeine Tracker keeps your caffeine log, coffee timing, sleep cutoff, and recent trends together in one clear place.

All caffeine levels, curves, and cutoff times shown in the app are estimates for planning purposes. They do not measure caffeine in your body, predict sleep outcomes, provide medical advice, or replace professional guidance.
