On a mission to unify time, health, and finance by harnessing your own data as the source of truth.
Life management tools have always been fragmented. Calendar apps. Habit trackers. Budgeting dashboards. Sleep scores. Each one demands your attention. None of them share context.
Mark et al. (2008) found it takes 23 minutes to refocus after a context switch. Each fragmented app compounds that tax. Read the research
We were always told one app can't do it all. So everyone stitched together calendars, habit trackers, and budgets. That era ends here. Life management deserves to be reimagined as a unified, data-driven platform, starting from ground zero.
Time is how you spend the only non-renewable asset. Health is the ceiling on what you can do with it. Finance is what you trade it for. When the three start talking, new patterns surface.

Hi, I'm Wojciech. Lifestack is a one-person operation, built to solve the problem of fragmented life tracking. 100% founder-owned and independent. Just code that tries to deserve your attention.
My professional background is deeply rooted in data engineering and analysis. I've spent years as an Analytics Engineer and Data Engineer building pipelines, search algorithms, and segmentation models for teams that needed answers, not dashboards.
I hold a degree in Computer Science from Goldsmiths, University of London. For my dissertation I wrote Deep Neural Networks from scratch with pure math and NumPy to understand, not import, the mechanics of modern AI. I bring that rigorous, data-first approach to Lifestack.
No streaks. No badges. No shame spirals.
Every signal sharpens the next.
Your device. Your data. Your consent.
Your full day loads in 50ms.
Tracking focus hours by hand, column by column.
Automating the math. Still alone in a terminal.
Edge infrastructure. Real-time sync. One view of everything.
A script came next. Then a service. Then a platform. I built Lifestack because I was tired of switching between ten apps to understand my own day. I wanted one operating system for my life, where deep work, sleep, and runway all lived in view.
Every line of code here is written with one purpose: to help you reclaim your time and energy.
Connect your data. See the patterns nobody else can.
