The best free fitness app: how to choose

What to look for in a free fitness app

• Workout logging that is quick

  Templates, sets, reps, weight and rest timers, so logging a session takes seconds, not minutes.

• Nutrition in the same app

  Food search, meal logging and calorie and macro progress next to your training, so you review one week, not two apps.

• Progress you can read

  Session history, personal records and weight trends, so you can see whether the plan is working.

• Habits beyond the gym

  Daily check-ins for things like sleep and water, because consistency outside the gym shows up inside it.

• Free core features, clearly stated

  Check what is free before you build a routine around it. A good free app is clear about what you get.

• Works for beginners

  A simple start, so you are not overwhelmed in week one, with room to grow as you train more.
