Hi, Product Hunt ๐Ÿ‘‹ I'm Nao, cofounder and CEO of Lifestack! ๐Ÿš€ Today, weโ€™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 ๐Ÿ“† Our biggest conviction is that we believe health and productivity go hand in hand. While itโ€™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 โ€” resulting in burnout and ultimately reducing productivity. Everything is a balance! โš–๏ธ 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! ๐Ÿ”ฅ 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 โ€” finish heavy tasks when most energetic, small tasks when least energetic; rejuvenate by scheduling energy boosting activities ๐Ÿ“ฑWe are available both on the App Store and Play Store! We also have Chrome extension for those of you who prefer web browser calendars! ๐Ÿงญ 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 ๐Ÿ˜ Please follow my account on Twitter / LinkedIn, and spread the word about Lifestack!

This is a very interesting app. Iโ€™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
@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 :)
Hayato Waki
@simona_o_neill3 thank you! Looking forward to hearing your feedback :)

@simona_o_neill3 Congrats on the launch! Wishing you and your team an exciting journey ahead. What inspired you to create this?
tom
@simona_o_neill3 @kjosephabraham we wanted to help people achieve more in a more energy-conscious way! time management is really about energy management!
Ryan Hoover
๐Ÿ’ก 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
@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.
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
@gabe Exactly! Starting with calendar events, we are planning to combine more contextual data, like GPS and computer usage!
tom
@gabe @nao_yukawa yes the "context" is what we think is the missing piece from health apps!

Nao Yukawa
@german_merlo1 Thank you so much!!!
Frank Denbow
Really interesting concept. I really think it could work if I could throw tasks into a bucket and say these are things I want to do today and you can schedule it out for me based on my current calendar. More thoughts
Nao Yukawa
@frank_denbow Thank you so much for the review, this is very insightful! And yes, 'AI Scheduler' is definitely on our roadmap ๐Ÿš€

Excited for this launch! I schedule 8 zooms a day and know there can be a better way to use my time so I feel less frazzled at the end of the day :)
