Hi, Product Hunt 👋


I'm Nao, cofounder and CEO of Lifestack! Today, I’m excited to announce the launch of our web app and AI scheduler on Product Hunt 😺


Lifestack integrates with your calendar, todo lists, and wearable devices to help you schedule tasks and activities at the right time, factoring in your calendar events, circadian rhythms, stress levels, and more 🗓️


You all requested a web version so we quickly built one! The web app isn’t just a calendar view; it also comes with a Kanban board, making it even easier to time-block your to-dos 🚀


But that’s not all! Over the past few months, we’ve been working on our AI scheduler. With just one click, you can timeblock your calendar based on your energy levels. It’s still an early feature, but I’d love for you to try it out and share your feedback!


At Lifestack, we believe that health and productivity go hand in hand. By helping people schedule their days based on their energy levels, we want to make productivity feel more natural, sustainable, and effective. This is just the beginning, and we’re excited to keep pushing the boundaries of what’s possible at the intersection of health and productivity! 🔥


Please check out our launch posts on X / LinkedIn as well, and spread the word about Lifestack!

@nao_yukawa @masump hi masum! thanks for the comment! currently, the ai scheduler is run at the beginning of the day (or other times if you wish) and doesn't adapt beyond that currently. however, we have a few features like energy boosts that allow you to add energy-increasing events to your schedule if you do feel more stressed/tired. definitely on the roadmap though!

Hi, Product Hunt!


I’m Hayato, cofounder and CTO of Lifestack. Super excited to share what we’ve built with you all today! 🚀


Lifestack seamlessly integrates with calendars, to-do lists, and wearables to create a truly adaptive scheduling experience—enhanced by our AI Scheduler. We’ve tackled some exciting technical challenges along the way:

  • Fast web app development: Since our mobile app was built with React Native, developing the web version in React was smooth—we built the first version in just two weeks and have been improving it with our users through rapid iterations.

  • Custom UI innovations: We developed proprietary UIs like drag-and-drop scheduling and an energy-aware calendar to make time-blocking more intuitive.

  • Expanding integrations: We’ve added support for TickTick, Todoist, and more to ensure Lifestack fits seamlessly into existing workflows. Also, thanks to Terra API, integrating wearables like smartwatches was much easier than expected.

  • Building a scalable all-in-one platform: Lifestack continuously improves how it integrates your health data, interprets it, and makes it more actionable. You can export your health data into Lifestack to gain insights, and with our AI Scheduler, it becomes even more effective in guiding your day.

This is just the beginning, and we’re eager to hear your thoughts! Let us know what think and how we can improve. 🔥

Thanks!!
