AI has no favorite workout app

Run the same kind of questions at fitness apps and the leaderboard goes flat. The top app, Nike Training Club, is named in about forty percent of grounded answers. That is enough to lead but not to own the category. In budgeting the leader, YNAB, hit sixty. The rest of fitness splits across Hevy, Strong, Fitbod, JEFIT, Caliber, Strava and a long tail, none of them close.

Budgeting is close to locked in. Fitness is a scrum. The strength of "AI consensus" is itself a property of the category.

That is the useful part for anyone marketing an app. Where the assistants already agree, like budgeting, breaking in is hard. Where they don't, like fitness, the shelf is still open. A new fitness app has room. A new budgeting app is arguing with a settled answer.

The names work against them

Fitness has a different visibility problem than budgeting. Budgeting's was clashing brands: Copilot is also Microsoft's, Empower is also a retirement provider. Fitness's problem is plainer. The apps are named after ordinary words. Strong, Sweat, Ladder, Caliber. An assistant, and my own parser, struggles to tell "Strong" the lifting tracker from "strong" the adjective. A name that is a dictionary word is a tax on being recognised as an entity. Tellingly, Strong ranks near the top with the chat models but drops once Google's AI Overviews weigh in. The most search-grounded surface trusts the ambiguous name the least.

The other end of that scale: an app with no footprint at all. I track a brand-new indie workout app with no marketing behind it. It was named zero times, by any assistant, on any question. Not penalised, just absent. With nothing written about it across the web, there is nothing for the assistant to retrieve. Visibility starts with existing somewhere the model can read.

What this is

Thirty-four frozen questions across four assistants on the fast model tier, plus Google's AI Overviews captured from the web. US English. A preview, like budgeting. Two categories now share one method and show two shapes: a consolidated market with a stale ghost in it, and a fragmented one full of hard-to-name apps.
