Interval Timer : Custom Rounds

Interval Timer: Your Personalized Routine Manager
The ultimate timer application optimized for High-Intensity Interval Training (HIIT), Tabata, CrossFit, and all time-based workout routines. With intuitive setup and clear visual/auditory feedback, this app helps you focus entirely on your performance.

Key Features and Benefits
1. Total Routine Customization
Tailor every phase of your timer precisely to your fitness goals and current condition.

Warmup: Set a dedicated time to prepare your body before the main workout. This phase can be easily enabled or disabled.

Round Time (Work/Round): Define the duration for your high-intensity work periods.

Rest Time: Set the recovery period between your rounds. By disabling the Rest phase, you can implement continuous round training.

Total Rounds: Easily specify the total number of loops for your entire workout session.

2. Innovative Individual Round Control (Advanced Feature)
Move beyond timers that only allow uniform round durations. Activate the 'Individual Setup' feature to assign different durations for each specific round or rest period.

Example 1: Set your workout time to decrease as fatigue sets in (e.g., Round 1: 3 mins, Round 2: 2 mins 30 secs, Round 3: 2 mins).

Example 2: Flexibly set recovery strategies (e.g., Rest 1: 30 secs, Rest 2: 1 min) for optimal preparation for the next round.

3. Focus-Driven Feedback System
Stay fully engaged without constantly checking the clock, thanks to clear auditory and visual cues.

Dynamic Color Changes: The screen color dynamically changes based on the current phase:

Vibrant colors for Warmup.

Teal/Cyan tones for high-focus Rounds.

Calming colors for the Rest period.

Auditory Alerts:

Start/Phase Transition: A clear sound signals the beginning of each new phase, guiding your next action.

Countdown Warning: A warning sound plays 3 seconds before a phase ends, prompting you to prepare for the upcoming transition (end of rest or end of work).

4. Superior User Interface (UI/UX)
Circular Scroll Picker: When setting time, the app provides a smooth, infinite scroll wheel. Crucially, the maximum value (e.g., 99) seamlessly connects to the minimum (00), making time selection intuitive and fast. This design ensures users immediately understand the cyclic nature of the input.

Large Digit Display: During the workout, the remaining time is displayed in large, bold numbers for easy visibility, even from a distance.

Control Buttons: Provides accessible buttons for stopping the session, pausing/resuming, and quickly skipping to the next phase, offering full control over your workout flow.
