## What is ゴルフ スイング分析ショットナビ｜Golfヘッドスピード軌道?

This application allows you to data your golf swing and compare it without any special measuring equipment.
You can measure your swing on your iPhone and Apple Watch!
You can trace "your" good swing, not a professional golfer's swing.
Your best swing will tell you if you are "swinging too fast" or "not turning your hips".

--This app requires both an iPhone and an Apple Watch--

Swing Analysis is an application that requires monthly payment.
You can use the application for free for 2 months, starting from the date you set up your payment.
After the free trial period, monthly payment will be required.
If you cancel your subscription during the free trial period, no payment will be incurred.

◎Demonstration test of measured data
We conducted a demonstration test using a large research facility with motion capture and a high-speed camera.
We provide comparative verified data between the data analyzed by the research facility and the data from the application.

◎Quantify each point of swing
The iPhone and Apple Watch are used to convert your swing into data.
The iPhone measures the movement of the hips and the Apple Watch measures the movement of the arms, and the swinging motion is expressed in numbers.

1) Address to Top
-backswing (time)
--Measure the time from address to top

-Waist twist angle (degrees)
--Measure the waist twist angle at the top

2)Top movement
-Top turnover (seconds)
--Measure how quickly (or slowly) the hips start to move compared to the arms.

3) Downswing
-Arm acceleration (1) (seconds)
--Time taken from the top to the horizontal position of the arms

-Arm acceleration②（seconds)
--Measure the time from the horizontal position of the arms to impact

4)At impact
-Hip Speed (°/sec)
--Maximum hip speed before impact is measured

-Hips - Attenuation rate (%)
--Measures how much the hips stop rotating at the moment of impact.

-Impact hip angle (degrees)
--Measures how much the hips are open at impact compared to at address.

◎Comparison of Swing Data
You can compare each value of the measured swing and the swing data saved in the past.
You can also compare past swing data with each other.

*Notes for measurement*
When taking measurements, the pocket in which the iPhone is placed should be in the same position; the arm on which the Apple Watch is worn should always be in the same position.
Depending on the shape of the pocket of the garment, the iPhone may move significantly inside the pocket, which may cause an error in the value.
Half swings may not be measured. Therefore, wedges and putters cannot be selected in the club selection for use.

Operating environment
iOS13 or later (iPhone 8 or later)
WatchOS8 or later (Apple Watch series3 or later)
Some models may not be supported.

### 3/5 — 距離はどうやったら？

*2024-04-28*

練習で切り返しやらは出るが距離が全く出ない？
何か設定があるのかどうかわかる方いますか？

### 1/5 — ゴミ

*2023-03-13*

CMを見て興味本位で課金しました。スイング解析スタートしても一向に解析できない。
これはひどい。

### 1/5 — Apple Watchと通信不安定、スイング記録できない

*2023-01-08*

通信エラーばかりで使えない。
つながっても、スイング分析が終わらず、記録にも残らない。
このままでは使えない。

### 3/5 — 初心者

*2022-10-02*

確かにデータは取れました。切り返しや腕のスピード、腰と腕のスタートのズレまで出てました。おー、スゴい、と楽しみ半分で見てたのですが…。
だから、どうしろと…。ゴルフに詳しい人なら、そこ直そうとなるのでしょうが、出てくる数字に対して、いいのか悪いのか、許容範囲なのか、だからスライスが出るのか、全くわからない。

図々しいと思いますが、アドバイス的なものの出てくるのかと勘違いしていました。

私は使い切れません。これで分かる方がご活用ください。😅

### 1/5 — 使用の感想

*2022-09-11*

興味で早速試したが、データを収集するのに不安定で距離も一度も出ませんでした。今後の改善をよろしくお願いします。
