When does caffeine stop helping you — and start wrecking your sleep?
Log how much you had, where it came from, and when you stopped. After 30 days, our AI finds your personal cutoff time and the daily dose where caffeine stops earning its place — using only your own data, not someone else's rules.
"Over the past 30 days you averaged 280mg of caffeine a day — 220mg from coffee, 60mg from tea, with a median last-caffeine time of 1:40pm. The clearest pattern…

6 things Caffeine intake reveals about you.
- Your personal last-caffeine cutoff — the hour where sleep onset starts to drag and sleep quality falls
- Your personal daily dose threshold — the mg level where anxiety climbs without focus improving
- Whether your worst nights track caffeine timing, total dose, or specific sources (energy drinks behave differently from coffee)
- Whether delaying your first morning coffee actually changes your afternoon focus and your sleep — for you specifically
- Whether the headaches on your low-caffeine days look like withdrawal, and how that pattern is shifting over time
- How your weekend caffeine pattern drifts from your weekday baseline — and what it costs you on Monday morning
Here's what arrives at 30 days.
Illustrative — your analysis uses your own data.
Your caffeine intake patterns show a clear weekly cycle. AI finds the specific factors affecting your scores — after 30 days, your data tells the story.

People watching their own patterns.
Anyone who suspects caffeine is quietly shaping their sleep, anxiety, or afternoon crash but can't pin down whether it's the dose, the timing, the source — or all three. The person who has three coffees most days, sleeps badly two nights a week, and isn't sure if that 4pm flat white is the culprit or just an easy thing to blame. Also for the curious self-experimenter who has heard the "stop by 2pm" rule and the "delay your morning coffee 90 minutes after waking" claim and wants to know which — if either — actually shows up in their own data.
Common questions
Is the Caffeine intake tracker medical or diagnostic?
No. Unhide is pattern-insight for self-improvement — not diagnosis, treatment, or medical advice. The AI is explicitly prompted to avoid clinician language. If something concerns you, please talk to your GP.
Does the AI see my entries?
Only when an analysis runs — triggered in-app or delivered to your email. Either way, only your logged data and history is sent, never your personal information. Your data is never used to train any AI model. Full detail in the privacy policy.
What if I miss a day or two?
No streak guilt. Your insights stay accurate; the chart just has fewer dots. The AI explicitly works around gaps in your data instead of pretending they're zeros.
