Focus score is a structured self-rating (typically 1–10) of how easily you hold attention on a single task for an extended period, captured at a fixed time window each day. It is the primary outcome most users care about when testing a nootropic stack.
Why it matters
Focus does not have a good wearable proxy. Eye-tracking, app-usage metrics, and completed deep-work blocks are partial stand-ins, but the felt experience of "could I stay in the work" is what drives continued stack adherence or abandonment. For caffeine-plus-theanine, racetam-adjacent compounds, creatine, lion's mane, and most prescription-adjacent stacks, focus score is the signal most worth tracking.
How to log it well
Focus is highly context-dependent, so anchoring the scale matters:
- Log at the same time each day, ideally after the first 2-hour work block ends.
- Anchor your scale: 1 = "could not start," 5 = "worked in fits and starts," 10 = "flow, unbroken, rare."
- Log a simple context tag (meeting-heavy, writing, coding, admin) so you can interpret dips.
- Combine with tag-based logging for side effects so you capture both sides of any compound.
Common pitfalls
Focus ratings are especially vulnerable to sleep debt masquerading as stack failure and to placebo expectancy masquerading as stack success. The two most useful counter-moves are to always check the focus score against sleep efficiency from the prior night, and to run new compounds one at a time over at least a 2-week stack cycle before concluding anything. This discipline maps to the general approach in understanding dose windows and cycles.
How this appears in Unfair
Focus score is one of the default subjective proxy tracks for any stack tagged with a cognitive goal. It appears on the daily check-in prompt and is charted with stack adherence on the review screen.
Clinical safety note
A sudden and persistent collapse in focus, particularly with mood changes or sleep disruption, can indicate a medication interaction or developing mental-health issue. Those are clinician conversations, not stack-tuning ones.
