nGeneSwim

Review pool swims with Apple Watch tracking, iPhone statistics, 3D wrist-motion replay, distance correction, locker number, timer, and watch face complications.

nGeneSwim is a swim workout companion for iPhone and Apple Watch designed for pool-based swimming, Apple Watch workout tracking, iPhone review, local statistics, and 3D wrist-motion replay.

The Apple Watch app handles the pool workout from the wrist. The iPhone app supports pool setup, Apple Watch synchronization, recent-session review, visual statistics, and 3D replay after completed workouts.

Key Features

• Apple Watch swim workout tracking • iPhone pool setup and Apple Watch synchronization • Pool profile management with recent-pool selection • Distance, pace, speed, duration, heart rate, and energy metrics • HealthKit workout support when permission is granted • Motion-aware distance assistance using Apple Watch sensor signals • Distance correction for known straight-pool swims • 3D wrist-motion replay for reviewing hand and wrist movement • Visual iPhone session review with quick access to recent replays • Apple Watch face complications for swim distance, locker number, and timer • Compact Apple Watch interface optimized for small displays

3D Replay

nGeneSwim can collect Apple Watch motion samples during a swim session and transfer them to iPhone for 3D replay. The replay is designed to help swimmers review how the wrist and hand moved during a session. Recent sessions can be opened directly from iPhone statistics, and the latest replay may open automatically after a completed Apple Watch session.

Pool Management

Create and manage pool profiles on iPhone, including:

• Pool name • Pool length • Water temperature • Indoor or outdoor setting • Optional location note and coordinates

Pool profiles can be synchronized to Apple Watch for quick workout preparation.

Apple Watch Workflow

The Apple Watch app is designed for quick pool use:

• Select a pool • Optionally set a locker number or timer for the watch face • Tap Begin • Review distance, time, pace, speed, heart rate, motion, and distance confidence • Apply straight-pool distance correction when a known distance is available • Tap End to save and send the session to iPhone

Workout Metrics

During workouts, nGeneSwim can display:

• Distance • Duration • Pace and speed • Heart rate • Energy expenditure • Motion state and motion score • Wrist acceleration and rotation metrics • Pitch and roll orientation • Distance confidence indicators • Water status when supported by the device

Distance Correction

nGeneSwim includes a simple Apple Watch distance correction feature for known straight-pool swims. During a swim, the app can compare the estimated distance with the swimmer’s known distance and apply a correction factor for that pool.

This is intended to make motion-aware distance assistance more practical during real-world pool testing, especially when swimming style, arm movement, or kick-focused swimming affects sensor-based estimates.

HealthKit Integration

nGeneSwim uses HealthKit only when permission is granted by the user. Depending on device support and permission status, the app may use workout-related data such as:

• Swimming workouts • Heart rate • Energy expenditure • Swimming distance • Stroke count • Water temperature when available

Privacy

nGeneSwim does not require an app account, login, subscription, or external payment. Pool profiles, settings, and swim summaries are stored locally on the user’s devices. HealthKit permission remains controlled by iOS and watchOS.
