The origin story is embarrassingly relatable: my partner and I would spend more time choosing a movie than actually watching it. I have ADHD, and decision fatigue hits different when your brain treats every choice like it's life-or-death.
So I built Decision Jar — not as a novelty, but as a genuine tool for people who get stuck in choice paralysis. The shake mechanic isn't just a gimmick; the physical action of shaking your phone creates a commitment moment that breaks the overthinking loop.
A few things I'm proud of:
• The app is 100% local-first. Your decisions are your business — no accounts, no tracking, no cloud sync. It works offline because your lunch choice shouldn't require an internet connection.
• AI suggestions genuinely save time. Instead of staring at an empty jar wondering what your options even are, the AI fills it for you based on context.
• The gamification (streaks, achievements, stats) sounds silly until you realize it's training your brain to decide faster over time. That's real behavioral design, not just badges.
I built this with Expo/React Native, so it's truly cross-platform from a single codebase — iOS, Android, and web.
Would love your feedback, feature ideas, and honest takes. What decisions would you put in the jar?

The shake as a commitment device is a nice detail, most decision apps just present options without addressing the actual paralysis part. Curious how you handle decisions where the stakes feel too high for a jar shake to feel legitimate, does it stay scoped to low stakes stuff like lunch and movies, or do people try to use it for bigger calls too?
Congrats on the launch, looks solid. How are you currently thinking about acquiring early users and gathering feedback?
