This has changed how I think about planning my day. Seeing my energy patteren when I have tasks that require a lot of concentration, high priority or just something I know will take extra push to accomplish is really helpful.

awesome product! I always thought something like this was they way to go which is why I tried rise amongs other apps but all the data being separate meant a lot of manual inputs to really take advantage of time blocking based on energy but you solved it man! congrats

@alan_rivera Great that you used Rise! I loved it too, and it was definitely the inspiration of this product 😌

Congratulations on the Lifestack launch, Nao! Your timing couldn't be better - the intersection of productivity and wellness is exactly what many of us need. I love that you've built a system that respects our natural rhythms and energy levels rather than fighting against them. The integration with calendars, todo lists, and wearables creates a unified system that actually works with real life. The web app with Kanban view is a brilliant addition, and that AI scheduler sounds like it could be a real breakthrough for establishing sustainable productivity habits. Excited to see Lifestack evolve as you continue developing at this fascinating intersection of health and performance. Wishing you tremendous success with the launch!

I saw this product at the TechCrunch booth! It’s awesome! I love that it helps me understand whether I need to take a break or work hard based on my life cycle. The most attractive feature is that it tells me the best time to focus. Plus, I appreciate that it can be used on any device. Congratulations on the launch!
