Read full descriptionHide full description
This is an alarm clock that tells you the time. You can tell the time just by listening, without looking at the screen. It will repeat the time over and over until you notice it. This app is especially recommended for people who can't wake up to music. The alarm is stopped by matching the pictures. Match the pictures above and below to stop the alarm. The difficulty of matching the pictures can be set in advance by the customer. The design has been completely redesigned. Multiple designs based on red are available. The system has been completely redesigned. The operation has been simplified for stress-free use. A separate time signal has been added to the alarm. Do you ever fall asleep after stopping the alarm? After stopping the alarm, the time will be announced every 5 minutes until you close the app. Notes about this app: ※ Uses the voice notification function of the iPhone/iPad itself. If you do not allow notifications, the alarm function will end when you close the app screen. The app will work regardless of whether notifications are allowed, but we ask that you allow notifications to save energy and ensure reliable operation. Please note that if you are in silent mode or have the notification function of the iPhone/iPad suppressed, the sound will not sound. * The app will not close due to automatic sleep. The operation screen will be locked and the screen will remain displayed until the specified time. * If you leave the alarm on the lock screen for 30 minutes, the next alarm will not sound. In that case, please launch the app. (The next alarm will be automatically reset when the app is launched.) Do not expect music from this app. No music will be played at all. The sound does not support the 24-hour system. If the screen shows 8:00 p.m., it will announce 8:00 a.m. Please be careful. * For customers using Apple Watch We apologize for the inconvenience, but please select the notification tab from the Watch app on the iPhone home page and set it so that "Alarm Clock" notifications are not forwarded to Apple Watch. If this setting is not set, notifications will be forwarded to the Apple Watch and the app will not work properly.
