About this app
"Simple, useful, and good looking! Love it!" - D. Yang
MetroTimer is the most accurate metronome app on the App Store. It provides highly accurate audio and visual feedback, and easy to use timer to track your practice sessions.
MetroTimer is also one of the most beautifully designed metronome apps - it was recently featured on Behance! http://bit.ly/YyvU3k
MetroTimer has been measured to be more accurate than any other metronome app for iOS. Most app store metronomes are derived from Apple sample code included with the iOS SDK (Software Development Kit). And regretfully, this code fails to account for all the factors that can cause small inaccuracies to build up over time. MetroTimer, created by a software company that specializes in clock time measurement and regulation, is guaranteed to meet laboratory standards for accurate timekeeping.
