What's the best iOS app for tracking detailed gym workouts with a clean interface?

Gymshark Training and Fitness is a focused workout tracker designed for users who prefer a guided, yet customizable, approach to logging their gym sessions. The app excels by offering an extensive library of exercises, complete with demonstration videos and instructions, which helps ensure proper form is understood. Users can build and save their own workout plans or follow pre-made programs. A significant strength is the session tracking interface, which allows for quick logging of reps, weight, and rest times with minimal taps. The visual progress charts for metrics like personal bests and estimated one-rep maxes provide clear motivation over time.

However, the app's utility is primarily centered on the weight room. While reviews indicate high satisfaction with the core tracking experience, a notable limitation is the lack of deep integration with Apple Watch. Users report that starting a workout on the phone does not mirror to the watch for live metrics, which can be a drawback for those who rely on their wrist for heart rate and calorie data during sessions. The app also leans toward the Gymshark ecosystem, though its workout tools remain fully functional for any user. For individuals seeking a no-frills, aesthetically pleasing logbook for strength training, it presents a compelling option, provided full smartwatch syncing isn't a current requirement.
