Swimming Starter is a "precise start signal and cycle management" app for swim training. It's designed to help coaches and athletes (including individual trainers) maintain consistent intervals.

[Core Values]

Precise Timing: Displays seconds and milliseconds, countdown ("5-4-3-2-1-Start").

Consistent Cycles: Automatically starts based on sets, rests, and reps.

Optimized for Coaches and Individuals: Supports both group management and solo training.

[Key Features]

Start Signal: Select from audible (beep), screen flash, or vibration, or both.

Session Builder: Easily configure desired intervals/repetitions, such as 50m x 10 @ 1:30, 25m x 16 @ :40, etc.

Coach Mode: Start offset by lane (group), instant pause/resume, and skip to the next set.

Solo Mode: Maintain accurate cycles even on your own with earphones and waterproof speaker.

Warm-up/Down Presets: Save/load frequently used sets as templates.

Large Numbers/One-Touch UI: Intuitive operation even poolside (considering gloves and water conditions).

Log (optional): Records completed sets, total time, and average cycle time.

[Usage Scenarios]

Race Preparation: Build a 2:00 pace with 10 100m intervals.

Drill Sets: Automatically switches between drills like kick/pull/scapine and rests.

Group Lessons: Minimize collisions by starting groups A and B at 10-second intervals.

Solo Cycling: Perform 30-60 minute routines without a coach.

[Why is it needed?]

Removes the distraction of human verbal signals → Increases training quality by repeating the same conditions.

Decreases the burden of managing multiple people simultaneously → Increases coaching efficiency and focus.

Ensures "accurate cycling" even for individuals → Systematizes stamina and pace.

[Accessibility/Safety]

Audio/Visual Assistance: Provides high-pitched beeps + high-contrast flash + vibration.

Adjustable volume and flash intensity; compliance with indoor regulations is recommended.

Caution: The smartphone itself is not waterproof. A waterproof case/speaker is recommended for poolside use.

Supports offline operation (based on pre-saved sets).

Android 8.0 (Oreo) or higher recommended. Optimized for tablets and phones.

[Training Design Tips]

Fixed Pace: Maintain a consistent cycle, such as "50m x 10 @ 1:30."

Fatigue Management: Maintain quality in the second half by allowing 10-20% rest.

Group Operation: Minimize interference with lane-specific start offsets (e.g., +5 seconds, +10 seconds).
