works with your body

We override our bodies constantly — and pay for it. Sometimes we waste our peak focus and push through later on fumes. Sometimes we eat a heavy meal before an important meeting. Sometimes we sacrifice sleep for work that could wait. Lifestack plans your day around your body, so you stop working against it.

CUSTOMER STORIES
See how people use Lifestack every day

I can’t begin to explain how effective I’ve become since scheduling more demanding tasks at work when the app notes my high energy/low energy throughout the day. There’s no other app on the market that’ll let you not only see your current schedule with your energy peaks overlay but lets you also sync tasks from 3rd party platforms like Trello.

MICHAEL ROOKS

  • Prior to using Lifestack, I just planned based on my random thought process. Now I plan more according to my available energy levels, and it has been nothing short of great.

    DAVE MILLER

  • Before Lifestack, scheduling tools couldn’t sync satisfaction and efficiency into my busy lifestyle, leaving me feeling drained at the end of the day. Now, tasks on my calendar match my energy levels throughout the day, and life couldn’t be better.

    KIRTIS SIEMENS

  • I used to assign tasks that I had to do haphazardly, but after looking at Lifestack, I don’t think I will set important tasks that will take time during Energy-Calm. On the other hand, I feel a little more at ease if I already have plans during the Focus period.
