Dj it! - Music Mixer

Review by eFreeware

DJ it! - Music Mixer is a free Android app from Gismart in the Music & Audio category, and its pitch is simple: a full DJ setup squeezed onto a phone, with a teaching layer wrapped around it. The app offers decks, effects, loops and recording, plus a DJ Academy that walks you through mixing step by step. For anyone curious about DJing but not ready to spend on hardware or software, that combination is the main draw.

The app has been on Google Play since August 2020 and has passed 10 million installs, with a 4.4 average across more than 128,000 ratings. Those numbers suggest a large, settled audience rather than a novelty. What I find most interesting is the split personality: it wants to be both a practice tool for people who already mix and a classroom for people who have never touched a crossfader.

The most recent update, in December 2025, added sound packs and improved roll and gate effects and beat-sync. That tells me the mixing side is still being worked on, not just the lessons. Whether the balance between the two halves works for you depends on which side you came for.

The DJ Academy is the part that sets it apart

Most mobile mixing apps hand you a deck and wish you luck. DJ it! instead leads with DJ Academy, described as a personal learning hub with lessons, tutorials and practice material. The developer says it covers everything from the basics of beat mixing upward, and that the lessons are meant to work whatever your current ability. That framing is what makes the app worth a second look.

The Academy has three supporting pieces. There is a quiz that the app's smart system uses to assess your skill level, and further quizzes that let you level up as you score well. There is a glossary covering the vocabulary that trips up newcomers, including faders, pitch sliders, filters, channels, turntables, decks and mixers. And there are tips that go beyond definitions into technique, such as looping, hot cues and mashups.

I like the order this implies: learn the words, test what you know, then apply it on the decks. The glossary in particular is the sort of thing that saves a beginner a lot of confused searching, since DJ terminology is dense and often explained badly elsewhere. The quiz-based progression gives the lessons a shape, which matters when you are teaching yourself at home.

The developer promises you will be mixing like a veteran, which is the kind of claim every teaching app makes and none can guarantee. The structure is sensible: instruction, vocabulary, self-testing and a place to practice, all in one app.

A deck setup with the usual tools

Underneath the teaching layer is a mixing environment with the features you would expect from a mobile DJ app. Automatic BPM detection handles tempo, and tapping a track syncs it. There is a three-band EQ, and the audio effects sync to the BPM automatically, which is the detail that keeps a mix sounding deliberate rather than accidental.

The effects list is long: delay, reverb, flanger, gate, high-pass and low-pass filters, phaser, bit crusher, roll and reverse. Loops run from 1/16 up to 64 beats, and each deck supports up to four hot cues. For a phone app, that is a serious toolkit, and it covers the techniques the Academy teaches rather than just gesturing at them.

Recording is handled in HD, with mixes saved to your library automatically so a good session is not lost. The app supports MP3, AAC, WAV and AIFF, which covers the common formats you are likely to have on a phone already. Nothing here is exotic, but the pieces fit together: detect the tempo, sync the effects, loop a section, drop a cue, record the result.

What the app asks of you

DJ it! is free to download, and it is supported by ads and in-app purchases. The app is rated for Everyone and sits in the Music & Audio category. I would treat the free version as the starting point and see how far it takes you before deciding anything else.

The bigger requirement is time and attention. The Academy is built around lessons, quizzes and practice, and improvement comes from working at it. If you want an app that produces a polished mix with minimal input, this is not the shape of it. The tools are there to be learned and used.

You will also need music to work with. The app supports the major audio formats, so the tracks already on your phone are the raw material. I would go in expecting to mix your own files rather than pull from a service.

Finally, this is a phone-based setup. The developer's pitch is that you need one small device instead of a full kit, and that is the trade: convenience and portability in exchange for touchscreen controls rather than physical faders and jog wheels.

How I would approach it

If you are new to mixing, I would start with the glossary rather than the decks. Terms like fader, pitch slider, filter, channel and turntable are used constantly in the lessons, and knowing them turns the tutorials from confusing to straightforward. Then take the skill quiz, not because the result matters much, but because it will point you at the right level of material.

The sensible path is to pick one technique at a time. Hot cues come next: with up to four per deck, you can mark the points in a track you want to return to, which is the foundation of a live set.

Effects are where beginners tend to overdo it. I would learn two or three well before touching the rest. A filter sweep and a well-timed roll will do more for a mix than a dozen effects used at random.

Recording is worth using from the start. Because mixes are saved to your library automatically, you can listen back and hear what worked. That feedback loop, rather than any single feature, is what turns practice into progress.

Who this fits

The clearest fit is someone at the beginning of an interest in DJing who wants to understand the craft before spending money on gear. The Academy, the glossary and the quizzes are aimed at exactly that person, and the deck tools mean the learning happens on real controls rather than in the abstract.

The second fit is a hobbyist who already mixes and wants something to practice with away from a full setup. The BPM detection, effects, loops, hot cues, EQ and HD recording amount to a usable toolkit for sketching ideas or keeping your hands moving.

If you are looking for a finished-track production suite, this is a different thing: it is built around mixing and remixing existing tracks, and the developer's own framing is about learning to mix and making beats to dance to. The app knows what it is.

A free way into mixing, with a learning curve attached

DJ it! is worth installing if you want to learn what DJs actually do and you have a phone and some tracks to hand. The DJ Academy gives the app a purpose beyond a deck simulator, and the mixing tools underneath are broad enough to grow into. It is free, ad-supported and offers in-app purchases, so the cost of finding out whether it suits you is low.

The trade-offs are the ones you would expect. Ads and purchases sit alongside the free download, the teaching material asks for real effort, and the whole thing runs on a touchscreen rather than hardware. None of that is a flaw in the design; it is the shape of a mobile learning tool.

For a beginner who wants structure, the Academy plus the glossary and quizzes is a genuinely useful combination. For someone already comfortable behind decks, the practice tools and recording are the appeal. Either way, the app asks you to put in the time, and it gives you the pieces to do so.
