I'm working on an app called Limberly. It focuses on health and ergonomics for sedentary workers - probably most of us here :)
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.
This means doing sessions of resistance training (gym), running, biking, but also taking micro-breaks during work sessions and performing light exercises and stretches.
Research has shown[2] that taking short breaks during work reduces fatigue, and in some cases actually boosts performance.
There are plenty of running and gym apps out there, so Limberly focuses on the last part - helping you take micro-breaks, reminding you to change your posture between sitting and standing, changing which hand holds the mouse (if you're into that) etc.
It is still in early development, so if you'd like to help test and shape the app as we go, please sign up for the waitlist and I'll add you to the testers group. Feel free to also DM me here with any questions or feedback.
Oh, I am also writing a series of articles that explains it more in depth: https://prodzen.dev/articles/building-limberly-part-1-we-re-...
