Description

From the listing uploaded by “appupdater”.

Overview This is the official app for linking your smartphone with CITIZEN Bluetooth watches (Bluetooth® version 4.0 or later). The app, which works with Android models, enables you to set the time and the alarm for your watch, and to receive alerts for incoming calls, mails and texts. With CITIZEN Bluetooth Watch, you get to enjoy a handsome-looking analogue watch that tells the accurate time wherever you are plus the great convenience of a smartphone link. CITIZEN Bluetooth features CITIZEN’s proprietary light-powered technology Eco-Drive. Eco-Drive eliminates the need of periodic replacement of batteries or recharge via cable. Features 1. Time Sync Get the right time, all the time. When you connect with your smartphone, the time on your watch automatically updates to the current time (home time). 2. Local Time Get the time in any city around the world. Just touch the world map inside the app to set your watch to the time there (local time). 3. Call Notification Find out when you get a call. The watch emits a sound, vibrates or rotates the hands to let you know when you get a call. A filter function enables you to specify which callers will trigger alerts. 4. Message Notification Find out when you get a mail, text or SNS notification. The watch emits a sound, vibrates or rotates the hands to let you know when a new e-mail or SNS notification has arrived. You can select the apps for which you wish to receive alerts. 5. Alarm Set your alarm from your smartphone. Set your watch alarm using the smartphone app. The alarm can be set for different times for different days of the week. 6. Light Level Indicator See how much light—and power—your dial is getting. Find out how much power your watch is generating by tracking the light it’s exposed to on a daily, weekly or monthly basis. This unique function reflects CITIZEN’s status as a pioneer of light-powered technology. 7. Smartphone Search Find your smartphone easily. Mislaid your smartphone? Not a problem. Use your watch to locate your phone by getting it to emit a sound to indicate its whereabouts. (Range limitations apply.) 8. Link Loss Alert Get alerted when you’ve forgotten your smartphone somewhere. The watch emits a sound, vibrates or rotates the hands to let you know when the link between your smartphone and your watch is broken. This watch requires Android 5.1 or later. Optimized for iPhone 5 or greater. *Even if your smatphone is under the conditions above, there is no guarantee to use the dedicated app correctly on your smartphone. About Eco-Drive: Eco-Drive is a CITIZEN proprietary light-powered technology which eliminates the need of periodic replacement of batteries. Eco-Drive generates power from any kind of light—from sunlight to dim light—to drive the watch, and stores the surplus on a rechargeable cell. On a single full charge it can run for up to six months in total darkness*.
