Summis

The science of cognitive performance.

Coming Soon to iOS

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.
