Killed Plant30
Plant30 tracked eating variety — 30 different plants a week, with a capture flow, a herbarium, and a weekly report. The build was fine. The pull wasn't there: I stopped opening it myself, and a tracker you don't open is already dead.
I keep a written rule for hobby projects: every app is an at-bat, and an at-bat that doesn't pull gets shelved fast so the next one can start. Publishing the kills matters as much as publishing the ships — otherwise the log is just marketing.
