Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Zach started lifting in high school to get girls' attention. Fitness is "30% training, 70% diet," and he found calculating how many calories he ate every day too much of a hassle — so he pulled together a few friends and built an app: photograph your food, and AI automatically calculates the calories. The crew coded day and night in a San Francisco hacker house, and the app exploded the moment it launched: 5M downloads in 8 months. Note the pattern: not chasing a trend — eliminating a real hassle of his own.
