iPhone
Where did the shuttle land? Don’t argue—replay it. Use slow motion, frame stepping, and a closer look at the key moment. One phone works; multiple phones add more angles.
FanEye is built for badminton training, casual games, and amateur matches.
Where did the last shuttle land? If no one saw it clearly, don’t argue—replay it.
FanEye keeps recent footage on the phone. When a point is disputed, tap Challenge to enter slow-motion replay. Pause, play slowly, jump one second, step frame by frame, and pinch to zoom into the area that matters. After reviewing it, players on site make the final call.
One phone is enough
Use one iPhone to record, challenge, and replay. For training, casual games, or memorable moments, take out your phone and start.
See more angles with multiple phones
Online court rooms connect two phones for free. Pro expands a room to up to six phones, preserving different angles for more complete court coverage.
Each phone keeps its own video and syncs only actions such as start, challenge, replay, and return. One person taps and the other phones respond together, making different angles easier to review.
Professional for match environments
Professional includes all Pro features and adds local discovery and connection for 2–6 phones on the same stable local network. Local room discovery, connection, and replay control do not pass through a cloud room. Purchase, restore, or subscription entitlement checks may still require internet access and Apple services.
Replay that is easier to inspect
• Slow playback, pause, and frame stepping
• One-second jumps to find the key moment
• Zoom the main replay up to 4×, with a fixed 7× landing-detail view
• Full view of the captured frame
• Optional Clear display mode
• Save key moments to Photos
No FanEye account. No video uploads.
FanEye does not require an account. Captured video is cached temporarily on each phone and is not uploaded to the server. A clip is added to Photos only when you choose to save it.
Online multi-phone rooms transmit only temporary room codes, phone roles, and necessary control commands—not challenge video. Professional local connection and replay control work within the same local network.
About decisions
FanEye is not an automatic referee and does not replace an official tournament line-call system. It does not automatically detect the shuttle landing point or call IN or OUT. FanEye preserves the recent footage; players on site make the final decision.
Clear changes only the on-screen replay appearance. It does not modify the original video or change the actual content of a saved clip.
Subscriptions
Online rooms connect two phones for free. For more angles, choose an annual auto-renewable Pro or Professional subscription.
Room creation and capacity depend on the controller phone’s current entitlement. Other participating phones do not need to purchase or sign in with Apple. The actual price and currency are shown by the App Store before purchase.
You can restore purchases in the app or open Apple subscription management to view, manage, or cancel auto-renewal.
