Cal AI didn't win because of the product. Anyone can vibe code a calorie tracker in a weekend now.
They won because they ran the distribution -> learn -> iterate loop faster than everyone else.

The founders who figure out how to run 50 growth experiments at the speed they ship 50 product updates will eat the rest of the market.
