About this app

FitStack is a straightforward, zero-fuss exercise rep tracker designed for people who want to skip the setup menus and get straight to their workout. No goal-setting screens, no complicated profiles—just start a session and begin training.

Whether you are focusing on push-ups, squats, or rope skipping, FitStack handles the logging so you can focus on the physical effort.

How It Works:
1. Start Your Session: Open the app and hit start to begin your workout immediately.
2. Complete Your Reps: Track your sets for push-ups, rope skipping, squats, and more.
3. Manage Your Rest: Need a break? Pause the active session to track your exact rest period length before starting your next set.
4. Finish & Review: End the session to get an instant, detailed summary of your hard work.

Session Stats Tracked:
• Total Reps: The cumulative number of repetitions completed during the workout.
• Calories Burned: Estimated energy expenditure based on your session activity.
• Active Workout Length: The total clock time spent actively moving.
• Rest Log: The exact amount of time spent resting during paused intervals.
• Historical Comparison: View your session data side-by-side with your previous workout to see if you outpaced your last performance.

FitStack is lightweight, fast, and stays out of your way, serving as the ultimate companion for clean, habit-focused exercise logging.
