Introducing "WorkoutTimer Pro Max". How do you manage your workout sessions? This app is designed to help you exercise based on time intervals. First, on the Workout List screen, each main workout contains one or more sub-workouts. When you create a main workout, the process automatically includes one sub-workout by default. The created sub-workout comes with default values, and you can choose to save your preferred values using "Save" or "Save as Default" options. Rest time between sub-workouts can also be modified and configured. Once created, you can start your main workout. When a main workout begins, the app provides voice messages to let you know which exercise you're currently doing and how much time remains for the current sub-workout. When you complete your workout, you can view your workout history in the Workout History section. On the Workout History screen, you can review all the workouts you've performed. You can easily browse your workout history using either a calendar view or a list view. The Settings screen provides various features: 1. Voice settings are available for customization. 2.
