Hi, Product Hunt 👋 I'm Nao, cofounder and CEO of Lifestack! 🚀 Today, we’re launching Lifestack - the only calendar app with your energy in mind! Lifestack uses health data from your wearables and smartphones to help you schedule around your most productive times 📆 Our biggest conviction is that we believe health and productivity go hand in hand. While it’s ideal to aim for 8 hours of sleep, 2 hours of exercise, and 30 minutes of meditation, this advice is not feasible nor sustainable for busy individuals. On the flip side, chasing the most productivity without regards for our health can have adverse effects — resulting in burnout and ultimately reducing productivity. Everything is a balance! ⚖️ So far 300+ users participated in our closed beta in the past couple of months, and today, we're finally opening it up to EVERYONE! 🔥 How Lifestack works: - Connect your health data from wearables and calendar to our app - Understand your energy levels (currently with sleep-based circadian rhythm) - Import tasks from your to-do lists to schedule them directly on calendar - Optimize your day based on your energy — finish heavy tasks when most energetic, small tasks when least energetic; rejuvenate by scheduling energy boosting activities 📱We are available both on the App Store and Play Store! We also have Chrome extension for those of you who prefer web browser calendars! 🧭 What's coming up next: - Web app version - Advanced biometrics (stress, HRV, glucose) - Todo integrations (currently supports Trello; adding Todoist and TickTick soon) - AI Scheduling If you've read this far, I assume you're really interested in us 😏 Please follow my account on Twitter / LinkedIn, and spread the word about Lifestack!

This is a very interesting app. I’m curious to give it a go and see if what the data says is true to how I actually feel. How long does it take to gather enough data to suggest the best times for different tasks?
Hayato Waki
Maker
@simona_o_neill3 Thank you so much Simona! We'll ask you to sync your health data initially, which allows our system to personalize your energy levels. This process takes just 3-5 seconds. After that, you can receive all of our suggestions almost in real time! Feel free to let us know if you have further questions. We look forward to hearing your feedback :)

How accurate are the energy level predictions from wearables? Also, can it sync with Google Calendar?
Nao Yukawa
Maker
@memphys_sk Our energy calculation is based on circadian rhythm, which a pretty established research area. And yes, it syncs with Google Calendar and Outlook Calendar too!

Integrating health data to optimize daily scheduling is innovative. How does the app adapt to individual users' changing health metrics, and are there any plans to integrate with more wearable devices in the future? Congrats on the launch, Nao!
Nao Yukawa
Maker
@kyrylosilin We're adjusting their energy calculation based on users' sleep data everyday! And yes, we're planning to integrate with more wearables in the future! Let me know if you have any specific wearable in mind :)

@kyrylosilin we are working on integrating more real-time health metrics starting with stress! happy to chat more ~i like the idea

Gabe Perez
I often felt that health apps lacked "context" maybe you had too many meetings and that's why your sleep score suffered? I really appreciate that Lifestack's focus is on understanding how your day impacts your health and how to work with your calendar not feel like you're fighting it. Congrats on the launch @wakkihaya and @nao_yukawa!
Nao Yukawa
Maker
@gabe Exactly! Starting with calendar events, we are planning to combine more contextual data, like GPS and computer usage!
tom
Maker
@gabe @nao_yukawa yes the "context" is what we think is the missing piece from health apps!

Ryan Hoover
💡 Bright idea
This is clever. I'm curious if people will follow Lifestack's guidance. Some people know what they need to do (e.g. go to bed earlier) but lack the self-control.
Nao Yukawa
Maker
@rrhoover Thank you, Ryan, that's a great point! We're initially targeting those who are motivated, but we will definitely consider how to provide value to those who struggle with self-control.
