A Fantastic All-in-One DJ App

I've been really impressed with Tremor. The interface is clean and easy to navigate while still packing in a ton of professional features. The beat sync and controller support work great, and everything feels smooth and responsive. It's clear a lot of thought went into the app, and I'm looking forward to future updates!

Serious DJ Software for Mobile

Tremor feels surprisingly close to real desktop DJ software on iOS. The stem separation and beat sync work really well, and the interface is smooth and responsive. Love the controller support and multi channel audio features. You can tell a lot of thought went into this app. Definitely one of the most impressive mobile DJ apps I’ve used.

Genuinely original, finally a DJ app that does video

Been using Tremor for a few hours now and just upgraded to Pro and wow. The video on vinyl feature is something I haven’t seen in ANY other DJ app on the App Store and you can actually play music videos right on the turntable platter while you mix. That alone is worth it. The AI stem separation is incredible too, I can pull out vocals or drums in real time and remix on the fly. Neural beat detection has been spot-on across every genre I’ve thrown at it, even tracks that usually trip up other apps.
Pro unlocked a ton for me like stems, 4-deck mixing with the orbital fader, AirPlay video streaming, and the split output so I can finally cue properly on my audio interface. Also love that they kept all the original free features actually free instead of paywalling everything.
Small thing, I would love a few more FX options eventually but this is hands down the most creative DJ app I’ve used on iOS. Whoever’s behind this is cooking.

DON'T GET IT!

It wouldn't let me get out of the app. I completely turned my phone off and shut it down and hooked it up the the computer and finally I took it in to get fixed. DON'T GET THIS APP!!

Bad update and no support

I updated the app recently, most of the earlier features are gone. Sone buttons like the earphone options don't work. Worst of all the support site shows an "error 404"!!
