Editors’ Choice

Pacemaker’s beautiful, minimalistic design shifts the focus away from knobs and faders while still providing all the controls and effects needed to create great mixes. With Autopilot, simply queue up your tunes and the app can mix for you. While you’re manning the tables, Pacemaker can provide you with song recommendations, which you can tweak with tons of effects available for purchase. This Apple Design Award winner is all you need to get a party started.


Really great

I find using the app to be super intuitive, you don’t need much experience and can be mixing in matter of minutes. The auto is function works better than any other I’ve tried, which it great at parties when you just want to leave it playing.

The interface is really easy to use, it just makes it very obvious how everything works and I don’t think the charges for extra effects are to high if you decide you need them.

I gave the app 4 stars because I really wish I could connect this to my mixer, the ability to mix and monitor would make it perfect, it just won’t talk to my Traktor which is frustrating.

A valued fan ,

You have ruined this app!

When I first downloaded Pacemaker, I absolutely loved it! I thought the concept was basic, the implementation was intuitive and generally fun to play around with. After some time, I had made 4 or 5 mixtapes consisting of 100 mins + of music, each track placed with precision - literally spent hours making mixtapes that sounded good and flowed well! Now all of that has gone to waste since your update of sourcing tracks from two labels...

Every track on my mixtapes have a “?” Symbol and don’t function at all! Hours and hours of time wasted! On top of that, you’ve made the app paid only! Before the update, it was free to use (with basic features only).

I feel like you lured users in with this free to use app, allowed them to invest time in making mixtapes, and then rendered the work useless! Then you expect them to pay?

I’m honestly disappointed! I hope you can fix this or find a solution. I would happily pay if my work wasn’t ruined by your update. (Even though you’re charging a ridiculous amount... £240 a year? Really?)

Hope you can improve.

Developer Response ,

We're really sorry about this, but we had no other options when Spotify decided not to support DJ apps. Our updated prices reflect that we now have to pay rightsholders for their music. This is a start, and as we add more content, things will get better and more of your amazing mixes will work again. Please bear with us. A reduced monthly tier is available to our loyal users. Please contact our support. We'll help you find it: or Twitter @pacemaker.
