Hi HN community,As a busy techie with kids and other family obligations and my recent health diagnosis, I wanted an efficient way to integrate workouts in my daily routine and my research indicated that HIIT/Tabata style routines fit that requirement much better than a dedicated long running/planned workout routine.I made a simple PWA to help me with that endeavor that I have found useful and hoping some of you may like it as well. No sign ups needed but you can sign in if you'd like to save custom presets and history/progress. You may also enjoy some of the fitness guides/blog posts that I am put together to help someone get started more easily. Built using javascript, vite and firebase.Feedback is most welcome, both via the app/email or comments here.
