What it is about
A performance tracker for your brain.
Clarity is built for people who have to think for a living: founders, managers, developers, marketers, consultants, agency owners, traders, and anyone who hates guessing whether today is a sharp day or an off day.
The loop is intentionally simple: play the Daily Check, get your Brain Score, read one useful insight, build your streak, and come back tomorrow to beat your baseline. The promise is not "how do you feel?" It is "how sharp are you today?"
Clarity Premium unlocks the real compounding layer: full history, trend breakdowns, sleep and recovery correlations, AI-powered insights, weekly recaps, and replays so you can see what makes your brain sharp.
Not endless brain games
The games are the measurement layer. The product is the score, insight, and habit loop.
Private by design
Health data is read-only, summarized on device, never sold, and never used for ads.
Premium has a job
Free gives the daily score. Premium explains what drives it and how your patterns change.
