The honest answer is that ear training on a phone is thin, and most of the tools producers recommend do not run on one at all. SoundGym has no iOS or Android app. Quiztones is Apple-only. TrainYourEars, EQ Academy and EarQuiz Frequencies are desktop software with no mobile build.
What does work on a phone: MixSense, which has native iOS and Android apps, browser tools built for a small screen including ours (full disclosure, we make that one), Bedroom Producer in a mobile browser, and EarMaster’s free mobile tier if you want musicianship rather than mixing. Everything below was checked in August 2026.
Which ear training apps actually run on a phone?
Four, and only two of them are native apps. Here is the whole field with a plain answer in the phone column.
| Tool | Works on a phone? | Platform | Cost |
|---|---|---|---|
| Monosounds Ear Training (ours, so weigh that) | Yes, browser | Any mobile or desktop browser, built as a single column | Free, no paid tier |
| MixSense | Yes, native | iOS, Android, web | Free tier, paid prices shown only inside the app |
| Bedroom Producer | Yes, browser | Any browser, no signup to start | Free tier, 2 lives a day as a guest, 4 with an account |
| EarMaster (musicianship, not mixing) | Yes, native | iOS, Android, Windows, macOS | Free tier; Pro 7 is $59.95 perpetual for 2 computers |
| Quiztones | iPhone and iPad only | iOS and macOS, no Windows, no Android | Free on iOS with Pro at $4.99/month or $19.99/year |
| SoundGym | No app, mobile browser only | Browser | Free tier gives the same 3 games per workout |
| EQ Academy | No | macOS 13.3+ and Windows 10/11 desktop app | Free |
| TrainYourEars EQ Edition 2 | No | macOS and Windows standalone, not even a plugin | EUR 49 one-time |
| EarQuiz Frequencies | No | Windows, macOS, Linux | Free, open source |
Why is there no SoundGym app?
There isn’t one, and SoundGym say so themselves. Their help page states there are no iOS or Android applications and that the site runs in a mobile browser instead.
That is worth knowing before you pay, because SoundGym is the most expensive option in this space: $24.95/month, $142/year (marketed as $11.80/month) or $495 lifetime. If your practice time is a commute rather than a desk session, you are buying a desktop-shaped product and using it through a browser tab on a small screen. It works, but it is not designed for that. We compare the whole paid field in our SoundGym alternatives breakdown.
What works well on a phone
Browser tools that were designed for a small screen, plus the two native apps. In practice that is a short list.
MixSense is the closest thing to a real mobile ear-training app for producers. Native on iOS and Android with a web version, it drills EQ, compression, balance and panning, and effects, using streaks and an “Ear Score” to keep you coming back. It calls itself the “Duolingo of engineers and producers”, which is a fair description of the format. It claims 10,000+ users and 4.8 stars on both stores, though those are the vendor’s numbers. Free to start, and the paid prices are only shown inside the app, so you cannot compare them before installing.
Bedroom Producer runs in a mobile browser with no signup. Its Mix Trainer uses real multitrack audio for EQ, compression, volume and panning with adaptive difficulty. The limit is lives: 2 a day as a guest, 4 with a free account, so a phone session is short by design. Patron is $2.50/month and there is a $7.99/month Early Adopter tier that locks that price.
Ours is a browser tool built mobile-first as a single column, so it does not ask you to hit small targets on a wide desktop layout. There are 500 levels across 10 chapters, 54 exercise generators, and six answer formats: multiple choice, a slider you match by ear, quiz questions, ABX, ranking three clips, and a “fix it” mode with two knobs where the correct values make the audio identical to the reference. The first 10 levels need no account, it is in English and Japanese, and it is free with no paid tier. The obvious limit: it is browser-only, so there is no offline app and a tunnel with no signal ends your session.
EarMaster belongs here with a caveat. Its free tier runs on iOS, Android, Windows and macOS, with intervals and chords, 4 beginner modules and 3 preloaded courses. Pro 7 is $59.95 for a perpetual licence on 2 computers, with 4000+ exercises and exam prep for ABRSM and RCM. But this is musicianship, not mixing. It will not help you hear a 3 kHz boost or a fast attack.
Quiztones: good, but iPhone only
Quiztones is a solid mobile EQ trainer and it exists nowhere except Apple platforms. iOS and macOS, no Windows and no Android version.
On iOS it is free with a Pro tier at $4.99/month or $19.99/year; on macOS it is $19.99 one-time. You get 450+ quizzes, 95+ premium loops and an EQ Practice Mode. It is published by The Pro Audio Files, version 3.8.0 was updated in April 2026, and it is rated 4.6 stars from 344 ratings on the App Store. So it is maintained, which is more than you can say for a lot of ear-training software.
If you are on Android, there is no equivalent. That gap is the single clearest fact about mobile ear training in 2026.
What will not run on a phone at all
The strongest EQ trainers are desktop-only, and that is not going to change soon. EQ Academy is a macOS 13.3+ and Windows 10/11 app. EarQuiz Frequencies ships for Windows, macOS and Linux. TrainYourEars EQ Edition 2 is EUR 49 for a lifetime licence and is macOS and Windows standalone only, meaning it will not even load as a plugin on a channel in your DAW, let alone on a phone.
None of these are bad choices. They are just desk software, and no use if your realistic practice window is fifteen minutes on a bus. The full inventory of what is free and where it runs is in our roundup of free ear training tools.
Headphones, earbuds and where you are actually listening
What you can usefully train on a phone is decided by your headphones and your surroundings, not by the app. Some drills survive a noisy bus and some do not.
Frequency identification is the most robust. A 6 dB boost at 3 kHz is a large, obvious change and it stays audible on ordinary earbuds. Broad tonal balance and gross panning survive too.
The drills that fall apart on the move are the quiet ones. Compressor attack and release, predelay, subtle stereo width and low-end judgements all depend on small differences, and background noise masks exactly that. Low frequencies are worst hit, because bus and train rumble sits in the range you are trying to judge. Sound On Sound made a related point about SoundGym in 2021: reverb results can swing between headphones and speakers. If the room changes the answer, a bus definitely does.
Two practical rules. Use the same headphones every session, so you are learning the sound rather than relearning the transducer. And do not raise the volume to fight the environment; if you cannot hear the difference at a comfortable level, the session is not teaching you anything.
What to train on a phone and what to leave for the desk
Phone sessions are for pattern recognition, desk sessions are for anything requiring accuracy. Split them that way and the commute stops feeling like wasted practice.
- Good on a phone: frequency identification, boost and cut recognition, panning, obvious saturation types, hardware and synthesis quizzes. Anything with a large, clear difference.
- Awkward on a phone: compression attack and release, reverb predelay and size, narrow resonance hunting.
- Keep for the desk: stereo width, mono compatibility, phase and comb filtering, and anything below about 100 Hz.
- Session length: ten to fifteen minutes. Short sessions on more days beat one long one, and a phone naturally enforces that.
How fast any of this shows up in your mixes is the real question, and we answer it with what we actually see in how long ear training takes. Whichever tool you land on, feed it material you work with: our free Serum 2 preset pack gives you sources to bounce and drill against for nothing, and a Serum 2 preset bundle gives you enough variety that the ear cannot memorise the material. Then run the trainer in whatever ten minutes you actually have.
FAQ
Is there a SoundGym app for iPhone or Android?
No. SoundGym’s own help page states there are no iOS or Android applications, and the site runs in a mobile browser instead. A SoundGym Pro subscription costs $24.95/month, $142/year or $495 lifetime as of August 2026, and none of those tiers include a native mobile app.
What is the best ear training app for producers on Android?
MixSense is the main native Android option for mixing-focused ear training, covering EQ, compression, balance and panning, and effects, with a free tier. Beyond that, browser tools are the realistic choice on Android, since Quiztones is Apple-only and EQ Academy, TrainYourEars and EarQuiz Frequencies are desktop-only. EarMaster has a free Android tier but it trains musicianship rather than mixing.
Can you do useful ear training with earbuds?
Yes, for the drills with large differences: frequency identification, boost and cut recognition, panning and obvious saturation. Earbuds and a noisy environment make quiet differences unreliable, so compression timing, reverb predelay, stereo width and low-frequency judgements are better done at a desk. Using the same headphones every session matters more than which ones they are.
Is Quiztones available on Android?
No. Quiztones runs on iOS and macOS only, published by The Pro Audio Files. On iOS it is free with a Pro tier at $4.99/month or $19.99/year, and the macOS version is $19.99 one-time. There is no Windows or Android version.
Is there a free ear training app for phones?
Yes. MixSense has a free tier on iOS and Android, Quiztones is free on iOS with an optional Pro subscription, and EarMaster has a free tier on both platforms for intervals and chords. Monosounds Ear Training is free in a mobile browser with 500 levels and no paid tier at all, and Bedroom Producer’s browser trainer works on a phone with a daily lives limit.
How long should a phone ear training session be?
Ten to fifteen minutes is the useful range on a phone. This is pattern recognition, so it responds to how often you practise rather than how long each session runs, and short daily sessions beat one long weekly one. Stick to one drill type per session instead of switching between EQ, compression and stereo in the same ten minutes.
I run Monosounds.studio and make the packs myself. Ten-plus years of producing, 97+ releases, 16,000+ downloads. Every Serum 2 preset we ship passes a CPU check on a mid-range laptop and gets used in a real track before release. If it does not survive a mix, it does not go in the pack.
