Lifestack syncs with health data from wearable devices to optimize scheduling based on energy levels. It helps you plan deep work when you’re most productive and take breaks when needed—helping you get more done without burning out.

Love the concept behind Lifestack! 🎉 The integration of calendar events, to-dos, and wearable data like stress and circadian rhythms is such a smart approach — it feels like the productivity app we should have had all along.


The AI scheduler sounds especially interesting. How granular does it get when analyzing energy levels? For example, does it adapt over time as it learns more about your personal rhythms and habits? And curious if there are plans to integrate with other wellness data, like sleep quality from Oura or glucose data from wearables like Levels?


Also — the Kanban + calendar combo is a chef’s kiss move. 👏 Sometimes I need a high-level view, sometimes I need to plan my day minute-by-minute — having both in one place is perfect.


Congrats on the launch, Nao! 🚀 Definitely giving Lifestack a spin. Would you say the ideal user is productivity enthusiasts, biohackers, or just busy professionals who want more balance?

@williamrobertscott hi william! thanks for the comment!

currently, we integrate with almost all wrist-worn and ring wearables like Oura, Garmin, Apple Watch, etc. but have glucose monitors on our roadmap! in terms of energy levels, we have an algorithm that adapts to personal rhythms based on subjective feedback.

and yes, we love the kanban + calendar UI and other "planner" apps!

@bvonancken hi Brian! Yes it integrates with Apple Watch (via Apple health). Here is the list of integrations fyi! (https://lifestack.ai/integrations) Onboarding takes just a 10 seconds at longest :)

Hey @nao_yukawa & @wakkihaya , congrats on your launch.🎉 And always thank you for your nice product.

I love Lifestack because it integrates my health and productivity. One of the features I like the most is the automatic addition of productivity schedules to my Google Calendar. I use Reflect for PKM and the events in Lifestack always show the time as well, which is helpful for everything I do, especially for processing tasks and coordinating meeting times for the next day.


Most of all, I continue to support the team for their quick response to requests and corrections. Good luck.

Huge congrats to the team on launching LifeStack! 🚀 I've been using it for months now, and it has drastically boosted my productivity as a solo-founder with lots of responsibilities in and out of the office. One of my favorite features is how it connects with my Oura Ring. Being able to plan my day around my readiness score has been really helpful for my decision making. FINALLY, a calendar that adapts to my energy, not the other way around! If you're looking for a smarter way to structure your time, this is it. Wishing you all the success on Product Hunt and beyond!
