### 3/5 — your bunny wrote

*2024-11-30*

Сделайте русский язык !!!

### 3/5 — New update

*2024-08-11*

Not update new version watch not connect

### 5/5 — Casio PRO TREK B 70

*2023-10-22, version 3.0*

Ce que je reproche à cette application c’est qu’on est pas la capacité de localiser notre montre en cas de perte ce qui m’est arrivé il y a un mois j’ai perdu ma montre au cinéma et il était impossible de savoir où elle était j’ai dû en recommander une sur un site spécialisé vu que ce modèle n’est plus disponible mais si il y a moyen de localiser la montre j’aimerais bien qu’on m’explique comment car la notice c’est très compliqué à lire

### 2/5 — 使いやすさ。

*2023-06-20, version 1.1.8*

もう少し使いやすい方が有難い。 アングラーとしては、大きな港より、漁港の場所を充実させて頂きたい。 国内の情報を増やして頂きたい。

### 3/5 — Margini di miglioramento

*2023-04-23, version 1.1.8*

Potrebbe essere più intuitiva e semplice.

### 5/5 — Pro Trek

*2023-03-21*

Useful App

### 1/5 — Complicato

*2023-02-21, version 1.1.8*

Troppo complicato. Ho cambiato la batteria non si regolano più le lancette

### 4/5 — Tilt auto backlight will turn off by itself

*2023-01-23*

Very effective app just as their watches! Love the app and the watch which in my case is b70

But there is a bug which has been mentioned in some reviews that the auto backlight feature will sometimes turn it off randomly.

Additionally, it will be nice to have auto light on feature to be on only after sunset and before sunrise. I believe it is also supported by the firmware of the watch and should be easier to support in the app too

### 5/5 — 他に類を見ないほど・・・

*2022-11-15, version 1.1.7*

とにかく、多機能、月齢🌒、気圧🎐、コンパス🧭、タイドグラフ、歩数計、高度計、魚🐟の釣れた場所記憶、⬅️アプリと連携(PRO TREK connected)、アラーム、ワールドタイム。とにかく軽いので装着感も感じられません😆

これで、電波ソーラーは良いけど、二次電池交換時は高額になるのでこれが最適だと思います。
時間補正は、アプリ連携で全然問題なし！！😆出来ればチタンバンドがオススメ😎劣化や破損が少なめ、万が一バンドにキズがついても
浅いキズなら緑色のスコッチブライトで擦ればキズはほとんど消えます。

### 4/5 — Нужно доработать. Есть предложения)

*2022-11-12*

Нет синхронизации со стандартным приложением  здоровье. Нет возможности перевода часов на русский язык. Ну и давление можно было бы перевести в мм/рт. столба, так в РФ привычнее.
