Lifestack vs Levity

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.

Levity automates logistics email work that still runs through Outlook and Gmail inboxes. Freight teams connect millions of messages, classify track-and-trace, booking, quoting, and customs threads, then deploy production workflows that draft replies, extract shipment data, and push updates into TMS tools like Cargowise, Turvo, SAP, and Zendesk.

Generic automation builders treat email like a trigger. Levity maps Analyze, Build, and Scale as one loop: analytics surfaces repetitive request patterns, a visual flow editor turns them into guarded AI actions, and quality control queues human corrections before automations spread. That structure matters when a misread POD attachment can delay billing on a $3 billion freight account.

Carriers such as Gebrüder Weiss report cutting manual email work in half while keeping operators in the loop. Levity targets enterprise logistics teams processing high inbox volume and sells through demos rather than self-serve checkout.
