"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!

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.

Metronome Highlights:

● Tested with clock time regulation equipment
● Practice timer to track your practice sessions
● Visual indication allows you to "see" the beat
● iPhone LED flash visual feedback support
● 8 metronome sounds including human voice
● Background mode, blends with other audio
● Tap tempo functionality

Metronome Pro (in-app purchase) adds these features:

● Custom time signatures
● Accents and subdivisions
● Interactive beat editor
● Presets list

What’s New

The best I’ve used but could improve a bit

I play piano and the flute and this is so useful to me when playing. My teachers said I really need to have a metronome so I went online to find one. I have been using this for only 1 year and I have been improving my evening notes. This is great I recommend it. However, there are some troubles, when I’m in class, I turn the metronome on but sometimes no sound comes. It freezes a bit and I have to refresh.

Still, it’s really good!

It's awesome... I'm a drummer and I love the app. Not only is it great to practice with but it's also great to be able to throw on your favourite tempos to listen to when you're doing grocery shopping, or on your way to work, or interacting with other humans in conversation. It's user friendly interface is easy even for me to understand and the thought that went into functions show that the designers were most definitely either clever eggs...or clever people...Highly recommend it.. download it and your playing will totally improve...practice with it and the sky is the limit.

Just a little bit bad

I am a beginner in guitar and my teacher recommended this app to me, I have found it quite useful.
Though sometimes the app just freezes and it takes a while to get it working.
I also would really like if you could customise the tempos to your liking.
Other then that I am quite happy with what I have experienced so far!
