Introducing Atomic – the atomic clock of metronomes! Atomic is advanced, simple and intuitive. Packed with customisable features and bombproof precision timing control.

Features of Atomic include:

• Click Sequencer - design your own click patterns
• Tempo Advance mode - auto bpm increase
• Silent Click / Click Gap mode
• Moving click mode
• Save Setlists and click track settings
• Detailed Click Sound Designer
• Advanced time signatures
• Fully customisable color schemes
• Tempo range from 10 bpm to 300 bpm

The main metronome display shows the number of beats per bar in the center circle, with beat intervals displayed in the outer circle. The beat and interval segments count in time with the click, giving a novel and intuitive representation of musical measures and time signatures – this is particularly useful if you are working in a complex time signature or if you are new to musical concepts. You can change the tempo (bpm) of the metronome playback from the main display, and the number of beats-per-bar and intervals-per-beat can be selected in the Settings section. You can also design the click sequence by choosing which beats and sub-divisions are audible and a which are muted. From the Settings menu, you can also choose to audibly accent the first beat of each bar, and you can switch off the interval sound and display all together if you prefer a more simple setup.

You’ll most likely want to go straight to the Colors tab and set the Atomic display to your personal color choice. There are also many ways to adjust the sound of Atomic to suit your preference and practice scenario.

If you access the Sounds tab, you can adjust many sonic aspects of the beat and beat division click sounds. Firstly, the musical pitch of the main click and beat division notes can be selected independently from A5 (frequency = 880 Hz) through the musical octave to A6 (1760 Hz). Some people prefer a higher pitch click, whereas other prefer it to be lower, it also depends on the type of music you are practicing and the noise level in your practice room, which may help you decide what settings to use for the click. You can change the tonality of the beat or beat division click from a dull thud to something more musical with harmonic overtones. Equally, you can extend the click duration so it resonates for longer, or shorten it to be quite snappy. The relative volumes of the beat and beat division clicks can be set here also, and the overall volume of the app is set by the device’s normal volume buttons too.

There are some advanced tools to help you develop your musical timing in Atomic too. In the Tools section, you can select the Timing Advance mode and set the metronome’s tempo to increase or decrease every time a specified number of bars complete. There is also the Silent Click mode, which allows you to silence the click for a number of beats in order to check that you can stay in time while it is inaudible. You can set how many beats are audible followed by how many beats are silent, and in combination with the time signature that you have set, this enables advance timing control to be developed. The Tools section also has a Tap Tempo feature, so you can tap out a number of beats and Atomic will calculate what tempo you are indicating with your tapping.

The Atomic sound engine design prides itself on the highest possible accuracy, using every little bit of power within the advanced iPhone chipset. You’ll find that Atomic is as accurate as even the most professional digital-audio-workstation systems, such as Pro Tools or Logic Pro. In fact, we measure Atomic’s timing accuracy to the nearest 0.00002 seconds (that’s one in 50,000), so you can be sure the app doesn’t just look great, it will not let you down under any circumstances!

Off-beat clicks

This is amazing and goes way beyond what anything else out there out there does. I like to practice with a displaced click, where I perceive the click not as being on the beat, but being on say, every third 16th note. With a regular metronome, I always find it hard making the mental adjustment to feel the pulse against that when starting to play, but with this device, you can have a regular count-in after which it plays a displaced click. One new device, one years-old problem solved!

Excellent metronome app!

Simple to use yet detailed enough to really help students understand compound and irregular time signatures. The choose your own colour option is a lovely bonus. I’m recommending this app to all my music students!

Best metronome

Accurate and amazing for practice! I particularly love the customisation options: programming in bespoke missing beats is invaluable for groove practice - my favourite new bass buddy!
