Your phone measurably reduces your cognitive capacity — even when it's silent and face-down. That's not an opinion. It's a peer-reviewed finding from the 2017 "Brain Drain" study by Ward, Duke, Gneezy & Bos.
Summis is a cognitive performance coach built on that science. It guides you through evidence-based focus practices, tracks whether you actually follow them, then proves which ones work — with your own data.
How it works
Focus Sprints. 30, 45, or 50-minute deep work sessions based on Dr. Sahar Yousef's cognitive performance research at UC Berkeley. A four-phase protocol: intention, focused work, genuine rest, reflection.
Cognitive Hygiene Tracking. Evidence-based practices — phone placement, notification management, consistent stimuli — scored against your daily compliance.
The Correlation Engine. After 30 days: "On days you kept your phone in another room, your focus quality was 34% higher." Your data, your proof.
Chronotype-Aligned Scheduling. Peak / Dip / Recovery energy windows based on the Horne-Östberg framework.
