Petite amélioration

Depuis la dernière mise-à-jour il y a un petit mieux.
Maintenant le tick est détecté j’ai le message « too much noise ». C’est soit ça ou rien. J’ai essayé toutes les configurations possibles mais je n’ai pas obtenu satisfaction pour le moment.
Alors qu’avec mon iPhone 12 il n’y avait aucun problème, avec mon iPhone 17 pro ça ne passe pas.

バージョン1.28の効果

マイクゲイン設定の仕様変更により、1.27では"too much noise"が多発した条件(iOS 26 iPhone with EarPods mic)でも計測できるようになった。

ただしグイン調整は注意を要する。

Rate, Beat errorとamplitudeの3個の数値が安定して計測できるゲイン設定の範囲は狭く、私の時計と試験環境では特定のゲイン設定からプラスマイナス1外れただけで計測値が不安定になったり、全く計測できなくなった。

便利なソフトだが最新のiOSでは問題がある

Apple EarPodsをマイクロフォンとして時計に密着させて使用している。
iOS16.7の古いiPhone8では快適に動作するが、iOS26.5のiPhone14に全く同一の時計、マイクロフォン、測定環境のセットアップを接続すると、”too much noise”アラートが多発してしまう。特に検出アルゴリズムV3ではアラート多発で使用できない。2026年3月時点ではiPhone14と当時の最新iOSで正常に動いていたが、3月から6月の間にあったiOSアップデート以降”too much noise”アラートの多発が発生した。

Ne fonctionne plus après un changement de matériel

Depuis que je suis passé d’un iPhone 12 à un iPhone 17 pro, le micro de mes écouteurs, que j’utilisais avec succès jusqu’à présent, ne capte plus les ticks des mes montres.
Dommage…

Can’t use with bluetooth microphone

I tried with my air pods and an other bluetooth mic. it would be good if we can select the source. it always use the iphones internal microphone

FAQ

What does Watch Tuner Timegrapher do?

Watch Tuner Timegrapher is an application designed to test the performance of mechanical watches, both automatic and manual winding. It uses your device's microphone to capture the audible ticks of the watch and then displays a frequency diagram. It also measures key performance metrics such as rate, beat error, amplitude, and beats per hour (BPH).

How accurate is the app?

For best results, the app should be used in a quiet environment as background noise can affect accuracy. While a built-in noise-cancelling algorithm can filter minor sounds, complete silence is ideal. The microphone needs to be in close contact with the watch, ideally against the crown, to clearly capture the ticking sound.

Is Watch Tuner Timegrapher free to use?

Yes, the application is available for free. The provided data indicates no in-app purchases or advertisements, suggesting a completely free utility for watch enthusiasts.

What are the basic requirements to use the app?

You will need a mechanical watch (automatic or manual winding) and a compatible mobile device with a functioning microphone. For optimal performance, a quiet environment is recommended. Using a headset microphone can also improve sound capture quality.

What if I only need to measure rate accuracy?

If your primary need is solely to measure the rate accuracy of your watch and you do not require the frequency diagram or other detailed metrics, you may consider the 'Watch Tuner Lite' app. This application is specifically designed for that purpose.
