Quieter Timer — App Store rankings

About this app

The developer's US App Store description, in full.

This is a simple timer app that will either vibrate-only or play the gentle sound of a Tibetan-bowl when the timer ends. The built-in iPhone Clock app has a timer that's great–but every sound option it offers for when the timer ends is loud and jarring. Quieter Timer is an alternative that can be useful for meditation, or any time you want to set a timer without alerting the whole room around you when the timer goes off.
