A Better Way To Track & Review Badminton On Apple Watch
Yujie keeps in-match interaction on your wrist and post-match analysis on your iPhone. Score with micro-gestures, capture swings, heart rate, peak swing speed, and load, then review a session with metrics you can actually use.
Why this product exists
The first release is not pretending to be an automatic umpire. It focuses on the real problems on court: less interruption, fewer accidental touches, trustworthy capture, and useful review after play.
Interaction goal
Low interruptionUse gestures and haptics on court instead of repeated screen taps.
Review goal
Trustworthy takeawaysFocus on duration, intensity, swings, peak speed, and trends.
Platform model
Watch + iPhoneThe Watch stays lightweight while the iPhone handles the heavier UI and analysis.
Data portability
CSV + HealthKitYour session data can leave the app instead of staying locked in one place.
Product principles
Why Yujie fits badminton better
Yujie does not paste a generic fitness template onto badminton. It starts from the actual on-court constraints: interruption cost, sweaty hands, battery, and useful post-match review.
Interrupt the match as little as possible
Default to micro-gestures and haptics so the match stays the center of attention.
Make capture trustworthy before making analysis ambitious
Reliable score, swing, heart-rate, and load capture matters more than flashy claims.
Keep realtime on the Watch, complexity on the iPhone
The Watch captures and confirms. The iPhone explains, stores, exports, and trends.
Product boundaries
Explain what it is and what it is not
This is not legal padding. It sets the right expectation early so users do not imagine a different product than the one they are actually getting.
It Is
It is a low-interruption tracking tool
The goal is to finish a match with less friction, not to create another screen-heavy workflow on your wrist.
It Is
It is a post-match review tool
The output is duration, swings, peak speed, load, and trends you can review quickly after play.
It Is Not
It is not an automatic umpire
Yujie does not promise reliable point attribution for every rally from a single watch.
It Is Not
It is not a medical or lab-grade speed device
These metrics help training review. They should not be treated as medical advice or instrument-grade measurement.
Core features
Built around what a badminton session really needs
The point is not to look advanced. The point is to reduce friction during play, make review easier after play, and keep data portable.
Micro-gesture scoring
Use wrist gestures to score for your side, score for the opponent, and undo the latest point.
More court-friendly than tapping through watch screens.
Continuous session capture
Record IMU data, heart rate, score timeline, and key state changes while you play.
The goal is a complete match record, not a decorative dashboard.
Swing count & peak swing speed
Track valid swings and follow peak swing speed through the session.
Useful for quickly checking how much and how hard you played.
Load & heart-rate review
Combine heart rate, movement intensity, and swing density into a practical load summary.
Review intensity with context instead of staring at a single number.
History trends & personal records
Use the iPhone to review recent trends, session summaries, and progress.
Turn scattered sessions into a training timeline.
CSV export & HealthKit sync
Export to spreadsheets and sync into the Apple health ecosystem.
Data should be useful outside the app too.
Workflow
How one badminton session gets captured
This path should make sense in seconds. You should not need to read an entire landing page before knowing what the first step looks like.
Start quickly before play
Launch recording on Apple Watch without walking through a setup-heavy flow every time.
Use low-cost interaction during play
Only gesture when you need to score or undo. Keep the rest of your attention on the match.
Review on iPhone after the match
Check swings, peak speed, load, trends, and export options after you finish.

FAQ
Answer the questions users and search ask first
Who is Yujie for?
Yujie is built for regular badminton players who want post-match review and already use Apple Watch with iPhone. It is not centered on professional officiating or social features.
Why micro-gesture scoring instead of automatic point detection?
A single watch is not reliable enough to assign every point in real court conditions. Yujie chooses lower-friction, controllable scoring first so trust is not lost early.
What can I review after a session?
You can review duration, valid swing count, peak swing speed, basic load, heart-rate context, historical trends, and personal records.
Does Yujie support export and Apple Health sync?
Yes. Yujie supports CSV export and HealthKit sync so match data can live inside the wider Apple health ecosystem too.
