Google AI is a single web capture of the AI Overview for 6 of the prompts, not the full set, so treat its column as directional. Every other assistant runs the full prompt set once each.

How the numbers moved

One snapshot is a photo. The index is the film. Each monthly run adds a column here, so a climb or a slide shows up as a line, not a number you have to remember.

AI has no favorite here

The top workout app is named in fewer than four in ten grounded answers, and the rest of the field sits close behind it. No app owns the recommendation. For a marketer that means AI visibility in this category is still up for grabs.

Where you ask matters more than who leads

The leader, Nike Training Club, shows up in four of six Google AI Overviews but only one in five ChatGPT answers. The same app can be a default on one surface and much weaker on another, so a category's "AI visibility" depends on which assistant you ask.
