Ear-training apps for producers in 2026: what SoundGym, Quiztones, Syntorial, musictheory.net, teoria and ToneDear actually train

This is a desk review, not a test. We read what each maker publishes about its own tool on 28 October 2026, linked every page we used, and gave no scores. We'll add scores once we've trained with each one for a few weeks (see how we test and rank).

Two different skills

"Ear training" covers two skills that rarely live in the same app. Engineering ears hear frequencies, compression and space in a mix. Musical ears hear intervals, chords and progressions. A producer who only drills intervals can still miss a muddy 300 Hz build-up, and one who only drills EQ can still struggle to work out a bassline. Our view: pick one tool from each column, and don't pay for a second tool that trains the same thing.

What each one trains

Where a price says "not shown" or "not stated", the page we checked doesn't list one. We'll fill it in, in INR and USD, when we buy each one for testing.

Which one should you start with?

For mixing ears: SoundGym. It is the only one here that names compression, panning and space alongside frequency, and its daily-game format suits a ten-minute habit. The free tier caps you at 3-game workouts; Pro unlocks all 21 games and 5-game workouts.

For pure EQ drills on the move: Quiztones. It trains boosts, cuts and level changes with "no visual cues", so you can't cheat by watching a meter. It's iPhone and Mac only, sold separately on each.

For sound design: Syntorial. It's the odd one out: it teaches you to hear what each synth control does and rebuild a patch by ear. The free demo (22 lessons, no time limit, no card) is enough to tell whether the method clicks for you.

For intervals and chords, free: musictheory.net. Interval, chord, scale and note exercises run in the browser at no cost. If you want them offline, the same publisher sells Tenuto for iPhone and iPad with 24 customisable exercises.

For harder musical dictation: teoria or ToneDear. teoria leans into two- and four-voice dictation and harmonic progressions; ToneDear adds intervals in context, scale degrees and melodic dictation, which are closer to working out a part from a record.

What we think

The engineering tools are where the money is, and that's also where the gap is: none of the pages we read publish a price up front, which makes them hard to compare before you sign up. The musical-ear side is mostly free and has been for years. So our default for a producer on a budget is a free interval trainer plus SoundGym's free tier, and only paying once you've used the free tier for a month and kept the habit. That is our inference from what's published, not a tested result.

How we'll score them

When we test these, we'll use the scoring rubric and its published weights, with the same rules for each: how well the drills transfer to real mixes and parts, cost and limits of the free tier, platform coverage, and how much you can customise the drills to your weak spots.

If a maker thinks we've got a published detail wrong, tell us and we'll correct it here.
