Hey! I'm Ash ; enterprise architect by day, solo app builder by night. I built 4sight because I was tracking my health across 5 different apps and none of them could answer the one question I actually cared about: how does it all connect? My sleep tracker didn't know about my workouts. My calorie counter didn't know about my stress levels. 4sight pulls it all together and uses AI to find the patterns hiding between the data. Built it as a side project, bootstrapped, and would love honest feedback from this community.
