This alarm will wake you up with sounds and time chimes that you can't ignore. Doorbell...can you ignore it? Repeated Doorbell...can you ignore it? It will repeatedly tell you the elapsed time at one-minute intervals. It will also tell you the time on the hour and at times divisible by five. -------- It's simple to use. Just set the alarm time and close the app. When the time is up, you will be notified by voice. The alarm will continue to ring for 30 minutes if you leave it alone, so start the app to stop the alarm. The way to stop the alarm is to match the pictures. Match the pictures, top and bottom as a pair. Match all three pairs and wait 2-3 seconds. A button to stop the alarm will be displayed. Please note that the alarm will not stop if you match the same pictures in a horizontal row. You can change the difficulty of the picture matching. You can also set it to stop with one button. You can check the difficulty of the game in a test. It would be helpful if you could check the operation once before using the alarm. You can register up to eight alarm settings. It is convenient to set the times you frequently use in advance. 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 the app screen is closed. This app sleeps according to the iPhone settings, so the app will essentially be unusable. ※ Sleep is disabled when the alarm stop screen is displayed. Please note that no sound will be heard if you are in silent mode or have the notification function of the iPhone/iPad suppressed. ※ 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.) Don't expect music from this app. There is no music at all. The time signal of this app is not suitable for any purpose other than as an alarm. It is a powerful alarm, but it only sounds for 30 minutes. Humans sleep in 90-minute increments, with deep and light sleep alternating, and an alarm app cannot wake you up during deep sleep with sound alone. If you really want to wake up at that time, it would be helpful to use multiple alarms so that you are aware of it before the time you want to wake up. If you want to wake up 30 minutes earlier than usual, it would be helpful to go to bed 30 minutes earlier than usual. *To Apple Watch users We apologize for the inconvenience, but please select the Notifications tab from the Watch app on the iPhone home page and set it so that "T.Signal Alarm" notifications are not forwarded to your Apple Watch. If this is not set, notifications will be forwarded to your Apple Watch and the app will not work properly.
