VibeAlarm is a straightforward alarm clock available on the iPhone platform that utilizes only vibration to notify users. The app has two features: alarm and timer, and can also specify seconds, making it versatile for various purposes. Additionally, VibeAlarm can notify in the background for 1.5 minutes, and if in the foreground, it will continue to vibrate until the stop button is tapped.

One of the most useful aspects of VibeAlarm is that it allows for notifications, which can be enabled in the Settings App. Notifications are only used for time notifications, and the app does not use notifications for any other purposes. Overall, VibeAlarm is a simple and effective alarm clock that is perfect for those who want a quiet way to wake up in the morning or need to keep track of time without sound.
