Long-form research on the best fitness tracking apps

The articles below go deeper than a category ranking. Each one is the output of a structured multi-week test — a 127-reviewer cohort, a 16-week adherence study, a 15-week training block — written up by a named expert, peer-reviewed by a second, and updated as the apps change. Use them when you want the underlying data, not just the verdict.

Five deeply researched guides today, with more in the pipeline. Each links back to the underlying category ranking and per-app reviews — so you can drill from the article into the methodology, the data, and the individual app verdicts.

How do these articles differ from category rankings?

A category ranking page answers "which app should I pick in this category?" in a single scan — table, scores, top pick, FAQ. An article goes further: it walks through the methodology, surfaces the surprising findings, runs head-to-head comparisons, and answers the second-order questions a ranking can't fit (which app to pair it with, which mistake people make most often, how the category changed since last year). If you want the verdict, start with a category page. If you want the reasoning, start here.
