Vibrating Alarm Clock Timer is an iPhone app that provides notifications exclusively through vibration, ensuring silent alerts without any sound. Resembling the iPhone's built-in clock app, it offers immediate usability. Notably, the app does not vibrate on iPads due to the lack of a vibration feature on those devices.

The app features an unlimited number of alarms that can be set for free, with the ability to specify dates and receive repetitive notifications with customizable days of the week. Additionally, the timer function allows setting in seconds, displays progress visually, and continues counting even when the app is closed. Other features include background notifications and support for dark mode.
