Lifestack vs Atomic

Lifestack is a productivity planner that builds your daily schedule around sleep, recovery, and focus instead of empty calendar blocks. It reads wearable and health signals, maps energy peaks and calm periods across your day, and drafts a schedule that places demanding work when you can actually focus.

Most calendar apps treat you like a task executor with unlimited stamina. Lifestack treats energy, meals, and rest as first-class inputs, overlaying focus and calm zones on your calendar so you see when deep work fits and when lighter tasks make sense. That body-first layer is the trade-off: it is narrower than a general project manager, but it connects health data to scheduling decisions most planners ignore.

The product suits professionals juggling meetings and deep work, ADHD users who need external structure around energy swings, and anyone syncing tasks from tools like Trello while trying to protect sleep and meal timing. Apps run on iPhone, Mac, Android, and Chrome, with a desktop Mac download and browser extension for calendar access.
