What it does
FitnessAI is a workout-planning and logging app for home or gym training. It proposes sets, repetitions and weights, adapts exercises to available equipment and includes video demonstrations, progress views and Apple Watch or Apple Health connections.
Its central task is turning recorded training into the next proposed session. Log the exercise work, then review the suggested sets, repetitions and weights rather than rebuilding every workout from a blank page. Exercise swaps allow the session to reflect equipment actually available.
The site also describes shorter session options, technique videos and wearable connections. These are useful planning and reference features, but the algorithm's recommendation still needs the user's judgment about the session. The developer's App Store listing describes automatically renewing subscriptions. It does not clearly enumerate a permanent free feature set, so a free download should not be read as unlimited access to the planning service.
