Lifestack

Lifestack is an AI daily planner that learns energy patterns from wearables and schedules tasks during your cognitive peak hours, consolidating calendars and to-dos.

Lifestack differentiates itself in the crowded planner space by scheduling around your energy, not just your free time. It connects to wearables and health data sources like Oura, Garmin, Apple Health, and Fitbit to learn your energy patterns, then places demanding tasks during your cognitive peak hours and lighter work during dips. Each morning it builds a daily plan for you automatically. The app integrates with Google Calendar, Outlook, and task managers like Todoist and Google Tasks, consolidating everything into a single schedule rather than leaving tasks scattered across apps. The energy-aware approach is particularly aimed at knowledge workers, ADHD users, and deep-focus professionals who struggle to match their hardest work to when they can actually do it. Lifestack is deliberately focused on calendar and task scheduling; it does not try to be a notes, email, or knowledge tool. Pricing is low, at a few dollars a month or a modest annual fee, with a lifetime option and a short free trial on the annual plan. For people who want their planner to actively build and maintain their day around their biology, it is a novel and affordable option.
