Lifestack AI is an AI-powered smart daily planning app that analyzes your energy rhythm (along with health and calendar data) to intelligently schedule tasks, aiming to boost productivity, protect personal time, and support sustainable work-life balance.
Key features include energy-guided smart task planning, integration with popular calendars and task tools (Google Calendar, Todoist, Notion, GitHub), wearable connectivity for health data analysis, AI-assisted daily planning, cross-platform apps, and privacy-first on-device encryption.
It's not required, but connecting wearables like Oura Ring, Apple Watch can provide more precise sleep, heart-rate, and other health data, which may make energy predictions and task recommendations more personalized. The app can also pull basic data from your phone's health app.
Built with a privacy-first approach, health and calendar data are encrypted locally on your device. The company states it never sells or shares personal information, and you retain full control over your data.
It supports syncing with Trello, Todoist, Notion, GitHub for task management, and Google Calendar, Outlook for calendars.
According to official information, Lifestack AI offers a 7-day free trial. Subscription options include monthly, yearly, and lifetime plans; exact pricing is per the official site.
It is suited for professionals who balance deep work, meetings, and personal health (developers, managers), freelancers, students, and anyone who wants to plan daily tasks by energy state to boost productivity and prevent burnout.
It means the app predicts your energy and focus curves for the day based on your schedule, tasks, and optional health data, and automatically recommends placing high-cognitive-load tasks during peak energy and low-intensity activities during low-energy periods.
