How Fitness Reviewed ranks apps

Every ranking on this site is built from the same five-factor rubric: evidence & methodology, user outcomes, UX & habit design, data privacy, and value for money. We test apps for a minimum of 30 days, read the academic literature behind their claims, and weight long-term retention more heavily than first-week magic. Read the full methodology →

Goal-based app packs

One app rarely covers a real goal. We curate app packs by goal – stacks of 3–5 apps that work well together for things like sustainable weight loss, thriving on a GLP-1, building muscle, and sleeping better.
