Time tracker customize is a modern interval workout timer built for structured circuit training. Set up your session with a flexible number of rounds and exercises, choose exercise duration, rest between exercises, and rest between rounds, and start training with a clear, focused timer view that shows the current phase, remaining time, and total workout time. You can fully customize each exercise: give it a name (emoji supported), set a specific duration for every exercise, or quickly apply the same duration to all. During the workout, the current exercise name is displayed on screen, and you can optionally enable voice announcements so the app speaks the exercise name before each work interval (with emoji automatically ignored). Speech includes a selectable language mode to match your preference. Time Training also includes a complete sound system for motivation and structure: select and preview finish sounds, halfway cues, three‑second cues, and dedicated sounds for both “exercise rest” and “round rest,” including a Disabled option. Rest sounds are played at the end of rest phases, so you always know exactly when to move on. For convenience and consistency, you can save workouts to Favorites, rename them, and quickly load them again later. Completed sessions are stored in History so you can review past workouts and apply them again with one tap. The Settings screen supports translation via quick language selection, letting you switch the UI language with confirmation. Designed for real workouts, the interface is clean, fast, and easy to operate—so you can focus on training, not on your phone.
