Lifestack reads your biology and gives you one number: how much you can handle today. A battery percentage for your body.
Fully recovered. Your best hours are ahead.
Lifestack does. When your schedule demands more than your body can deliver, it warns you before you commit.

Based on Van Dongen et al. (2003), Sleep: chronic restriction to 6h reduces cognitive output ~50%. Pilcher & Huffcutt (1996), meta-analysis. Read the research
You're leaving on the table:
That's $37,440/year.
