A brain state tracker
Five states — Buzzing, Sharp, Flat, Foggy, Scattered — that capture how ND brains actually feel day to day. You pick one when you wake up and update it whenever it shifts — every check-in is timestamped. No wrong answer.
A condition recommender that learns
Twelve built-in conditions across four phases — primers, protectors, recovery, and resets — plus any tool you add yourself, which becomes a first-class option with the same standing as the built-ins. An on-device Thompson-sampling bandit learns which conditions work for your specific brain state, time of day, and ND profile. It starts from research priors and anything you tell it about yourself, and after roughly ten to twenty real outcomes in a cell, your own results outweigh both.
A flow logger
After any deep work block, log how long, how locked-in you were, what helped, what drained you, and which condition you used. 60 seconds. This is the data that builds your manual.
A focus timer that logs itself
Start a work session in the app — 25, 50, or 90 minutes, or no limit, with optional breaks that alert you even if the app is closed. When you stop, the log opens with the measured duration already filled in; you add what you worked on and how it went.
A flow forecast that says what it is
A small neural network predicts how focused you are likely to be given your brain state, ND profile, and time of day. It was trained on a synthetic dataset built from published research, not on real participants, and its weights are fixed. It calibrates against the sessions you log, and it tells you when it is still running on priors instead of your data.
Your operating manual
The Manual tab synthesises everything into a living document: your sharpest hour, your highest-flow brain state, your top helpers and drains, your streaks, what the recommender has figured out. The more you log, the sharper it gets.
