Hey all, this is a cool idea for a thread! I've found some intriguing projects I will be following.

After being a web-focused dev for my whole professional career, I am now developing a mobile app with Flutter.

The app is called Limberly, and it focuses on health and ergonomics for sedentary workers. Us, who sit for a living.

It is scientifically proven[1] that sitting is detrimental to our health, with increased mortality rates. The primary way to reduce the negative effects of sedentary work is to move, and scrolling through feeds on your phone doesn't count as moving :)

This means performing sessions of resistance training, running, biking, but also taking micro-breaks during work sessions.

Research has shown[2] that taking short breaks during work reduces fatigue, and in some cases boosts performance.

Limberly is still in early development, so it's basically a glorified collection of timers (for taking microbreaks, for switching between sitting and standing, and for switching your "mouse hand"), but I do have a clear vision of having a smart system that recommends specific activities to do during breaks, ergonomically setting up your workspace, coach you on correct posture, track statistics etc.

If you'd like to help me test and shape the app as we go, please sign up for the waitlist or DM me here.

P.S. I guess this is a required disclaimer these days: The landing page is static and mostly vibe-coded, but the app itself is not. I do use Claude Code to speed up certain plumbing and widget implementations, but the core architecture and logic are designed, vetted and programmed by myself. Being a solo dev, it is important for me that I understand what every class and function is doing.

P.P.S. I don't like using scare tactics like "SITTING IS KILLING YOU!!" but it is sadly a fact. Also, I'm not selling you anything, as the app is free to use :)

Investing in standing desks, HM chairs and split keyboards is definitely a good idea, but what matters most is movement and changing your pose constantly.
