asambl vs Lifestack
A week built on the energy you declare, not your wearable's readings
Lifestack is a smart daily planner that reads sleep, recovery, and focus from your connected health data and re-plans your day around it. asambl takes the other approach: once a week you say what capacity you actually have, and it drafts your whole week (work, training, people, money, joy) as a Plan A, B, or C you approve. No wearable, and your vault stays on your computer.

Why people switch
What asambl does that Lifestack does not
You declare your energy; nothing straps to it
Lifestack needs your sleep and recovery data to know how you are doing. asambl just asks. In the weekly ritual you say what capacity you have, and it drafts a Plan A, B, or C to match: no wearable, no sync, no score.
A whole week, not a rolling day
Lifestack continuously re-plans the day in front of you. asambl drafts the whole week in one sitting, so training, people, money, and joy get placed before work swallows the space.
Your life, not just your workday
Lifestack points its energy model at getting the right work done at the right time. asambl plans across five life areas (health, finance, relationships, joy, growth) in one weekly plan.
Private, framed honestly
Lifestack runs on connected health data in its cloud apps. asambl keeps your vault on your computer; when AI is on, only that one request's prompt leaves, and you can turn AI off.
