FAQ
Common Questions About Yujie
This page answers the questions users, search engines, and AI summaries are most likely to extract, so the product scope and facts stay clear.
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.
Why split responsibilities between Apple Watch and iPhone?
The Watch is better for capture and instant feedback. The iPhone is better for detailed UI, history, settings, and heavier analysis.
What is Yujie not trying to be right now?
It is not positioning itself as an automatic umpire, a professional tactical platform, or a fully independent watch-only product in the first release.
