Summis

Your phone reduces your cognitive capacity even when it's silent and face-down. That's not an opinion — it's a peer-reviewed finding from Ward et al. (2017), published in the Journal of the Association for Consumer Research. Summis is built on that science. It coaches you through evidence-based focus practices and then proves which ones actually work — with your own data. Most productivity apps measure inputs: screen time blocked, notifications silenced, apps restricted. Summis measures the output that matters: did your focus actually improve? HOW IT WORKS Focus Sprints Guided 30, 45, or 50-minute deep work sessions based on Dr. Sahar Yousef's cognitive performance research at UC Berkeley. Each sprint follows a four-phase protocol: set your intention, enter focused work, take genuine rest, then rate your focus quality. The app coaches you to create the right conditions for deep work — then gets out of your way. Cognitive Hygiene Seven evidence-based practices that remove cognitive drains from your environment. Phone placement, notification management, consistent stimuli, and more. Summis tracks your daily compliance and connects it to your actual focus performance. The Correlation Engine After 30 days of data, Summis reveals personalized insights like "On days you kept your phone in another room, your focus quality was 34% higher." No generic claims. Your data. Your proof. Chronotype-Aligned Scheduling Configure your sprints around your biological peak performance windows. Whether you're AM-Shifted, Bi-Phasic, or PM-Shifted, Summis maps your energy phases (Peak, Dip, Recovery) and coaches you on which type of work fits each window — based on the Horne-Ostberg chronobiology framework (1976). Most Important Tasks Set up to three MITs each morning. Stay focused on what matters most. No endless task lists — just the three things that move the needle today. WHAT MAKES SUMMIS DIFFERENT Other apps tell you to use your phone less. Summis proves whether that actually makes you more focused — and which specific practices drive the biggest improvement for you personally. Total daily interaction target: under 5 minutes. This is the app that coaches you to use it less.
