The problem isn’t caffeine. It’s timing.

Caffeine is useful and most of the time, it does its job.

Then you hit an afternoon crash, a restless night, or the pull for another cup, and it doesn’t add up. The problem isn’t caffeine itself; it’s timing and awareness.

The effect keeps going long after it feels like it should be gone, but you can’t see it. Without a clear picture of what’s still active, the day feels inconsistent. When you can finally see it, everything makes sense.

Why tracking matters

Caffeine leaves the body by degrees.

Its half-life means the amount fades in stages, not all at once. Tracking makes the tail visible. A cup from earlier can still be active at night, even when the feeling has eased.

Without tracking, timing feels inconsistent. With a clear view, the carryover makes sense.

Logging drinks vs tracking caffeine behaviour

Logging drinks records what was consumed and when.

Tracking shows what caffeine is doing in the body over time. Clarity is a caffeine tracker built in the UK with a focus on timing and awareness.

Quitting caffeine isn’t required; timing is the lever.

Logging drinks

Logging drinks records what was consumed and when. It is a record of intake.

Tracking caffeine behaviour

Tracking caffeine behaviour shows what caffeine is doing in the body over time, even after the drink is gone.

Clarity Intelligence

Clarity Intelligence interprets the tracked data and highlights the patterns already there.

It is a calm, secondary layer that adds understanding without prediction or advice. Intelligence builds on tracking; it isn’t a separate system.

Built in the UK

Clarity is built in the UK and maintained with long-term intent.

The focus stays on timing, awareness, and a calm experience that stays out of the way.
