I am a developer with bipolar disorder. Tomorrow, I am launching a mood tracking app I built for myself on Product Hunt.
I tried various existing mood trackers, but found it difficult to keep up with them on bad days due to having to input multiple items. So, I created an app that requires "just two slider, taking only 10 seconds."
When I'm in a hypomanic state, I often feel "I want to add more features!" but I deliberately don't, because it would make the app unusable for me when I'm depressed. This "subtractive design" was the most challenging part.
Honestly, I'm nervous about the reactions I'll get tomorrow. Are there others who have built products to solve their own challenges in a similar way?
Most mood-tracking apps are either generic or data-overloaded. Daylio is versatile but not bipolar-specific. eMoods targets bipolar yet demands daily multi-point ratings—burdensome on bad days.
MoodTrend: two sliders, ten seconds. Designed by a developer with bipolar, prioritizing continuity on tough days. Share your chart with family in-app, and export as PDF for doctor visits.
Not more data, but finding your rhythm through subtractive design.
