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!

Not user friendly for set list performance

Bought this app to program song titles and associated BPM's for each song in a set list for performance.
Not a good application for this. After programming a 33 song set list, I found that when selecting a song I had to go to the metronome setting to have the metronome engaged but when going back to the set list it locks up not allowing me to select the next song to continue playing! Being the drummer in the band, I count off each song and need a set list that displays the metronome for each song and immediately allow for advancing to the next song. Unless I misunderstood the app, this is a big fail for me.

Hi there, the setlist feature should work 100% fine, select your set, then select the song you are playing, and then press the play button (which is a standard triangle shape pointing right). You’ll hear the preprogrammed click and see the metronome icon ticking away in time. At the end of the song, press stop (square button), select the next song and repeat - it works every time, so there’s no need to leave the setlists page at all during your show. The Atomic logo also doubles up as a play/stop button too. We’re committed to always improving the app so will continue to develop and see if any future improvements can be made, but the function you are asking for is already there within the app. If you email us asking for help we can easily send you some screenshots to help you find the right buttons to press.

Accurate and simple interface

Always looking for an improved metronome and this has some good features. I especially like the ability to customize the click and the sliding tempo adjustment that makes it easy to select a new BPM on the fly. If there was a way to run this in split view on the iPad it would be ideal for me as I'm using it live with a band and have some other apps that I would like to see at the same time. Otherwise thanks for the chance to try it out for free!

Thanks so much for posting your review. Great to hear! 🙏

Perfect build. Finally.

I have dreamt of a stable, easily navigable, and professionally competent metronome for years.

This is it. Aside from the color selection, which I find to be helpful for my eyes in low light studio atmosphere, it’s entirely streamlined without any unnecessary bells and whistles.

The menus for selection of time and division, as well as controlling for tone and sustain of sub counts in polyrhythm is thorough. It will be incredibly beneficial for exploring new playing to experiment with these settings when writing.

I would love to see this concept expanded into a common DAW compatible plug in. The mobile is everything it needs to be and then some, and this functionality inside Reaper or Pro Tools would be invaluable.
