The Best Fitness Apps for Android, iOS and Apple Watch in 2025

If you are searching for the best workout app iOS users can rely on, the right answer depends on how you train. Some apps are built to plan your lifting sessions, some are better for guided classes, and some are simply faster at logging reps, sets, and progress. If you want a clean lifting log, Setgraph workout tracker is worth a look, because its site describes it as a workout tracker gym log app with fast logging, progress comparisons, and an AI workout generator that adapts to your goals, schedule, equipment, and experience level.

The good news is that iPhone users have strong options across every training style. Whether you want strength training, home workouts, Apple Watch support, or a free app that keeps you moving, this list breaks down the best workout app iOS choices by use case so you can pick one that actually fits your routine.

How to choose the right iPhone workout app

The best workout app for iPhone is usually the one that matches your training style first, and everything else second. If you lift weights, look for fast set logging, exercise history, timers, and progress charts. If you prefer guided sessions, look for class-style videos and programs you can follow without planning every detail yourself. On iPhone, Apple Watch support and Apple Health sync can also make a big difference because they keep your data in one place and reduce friction during workouts. (strong.app)

A few other things are worth checking before you commit:

• Exercise variety: You want enough workouts, movements, or plans to keep the app useful over time. (fitbod.me)

• Logging speed: If recording a workout feels slow, you will eventually stop using the app. (setgraph.app)

• Pricing: Many of the best apps offer free tiers or trials, but the paid features can be a big step up. (fitbod.me)

• Apple ecosystem support: Apple Watch, Apple Health, and Siri Shortcuts are especially useful if you train with an iPhone every day. (strong.app)
