Comparison
iQuantize vs Drumeo for practising at home
Updated 3 August 2026
Drumeo shows you how it should be played. iQuantize measures how you actually play it.
Drumeo is a video platform with world-class instructors and an enormous library, and it is excellent at showing you how something is done. What it never finds out is how you did it — a video cannot know that your kick drifts late under sixteenths, or that your ghost notes have crept up to the volume of your backbeat.
So you can watch for a year, practise hard, and still have no way of knowing whether your playing improved or just became more familiar. That is the gap self-taught players stall in.
iQuantize reads every note you play, scores the take across seven skills, marks the bars where it broke, and picks the next groove from whatever is measurably weakest. Watching tells you what good sounds like. This tells you how far off you are, and closes the distance.
Which one fits you
You want your playing to change
You already have material to work on and want proof that your playing is improving — evidence, not a feeling.
You want to be taught
You want to be taught: technique, styles, reading and musicality, explained and demonstrated by excellent instructors.

What that buys you
Six differences that decide whether a month of practice actually changes how you play.
Seven skills measured, not one score
Most apps answer one question: did you hit the note near enough? iQuantize measures your take on up to seven separate skills — note accuracy, timing with the click, internal pulse, timing stability, dynamic control, dynamic range and limb independence — and scores only the ones the chart actually contains.
That is the difference between a mark and a diagnosis. One number tells you the take was 78%. Seven tell you the notes were right, the hands were steady, and the kick drifted late as soon as the hi-hat went to sixteenths — which is a problem you can go and fix tonight.
It takes the click away and watches what happens
Playing tightly to a metronome and having time are different abilities, and the first one hides the absence of the second. On grooves written for it, iQuantize drops the click mid-take, scores those silent bars separately as your internal pulse, and brings it back so you can hear where you ended up.
A wide gap between your two timing scores is the finding: you have been practising reaction, not time. It is the single most useful thing a teacher checks and almost nothing else measures it.
A coach's verdict, then one thing to do
Every take ends the way a lesson ends — a plain-language verdict, up to three prioritised observations about what actually slipped, a bar-by-bar map showing where it broke, and exactly one recommended next action.
One, not a dashboard. The failure of practising alone is not a shortage of numbers, it is having no basis to decide what to do with them.
The next groove is chosen for you, from your own data
iQuantize embeds every groove in the library as a vector describing what it actually trains, then picks your next one by nearest-neighbour search from your measured weakest skill — constrained so the step is never more than one level, never jumps from quarter notes straight to sixteenths, and never overshoots in complexity.
Scrape a pass and the next step shrinks. Clear everything comfortably and it opens up. There is no hand-wired lesson order to fall off: the path is built from the content and from you, which is what a teacher does between lessons.
You read real music, not a falling-block game
iQuantize puts engraved drum notation on screen — the same staff a teacher writes on, a band hands you, or an exam board prints. A moving playhead follows the bar and every hit gets a green, orange or red dot on the note itself, live, as you play.
A scrolling note highway is easier on day one and teaches you nothing you can carry. Learn to read while you practise and you can sit behind any kit, in front of any chart, and play. That skill outlives whichever app you are using this year.
It refuses to invent a number
When a take does not contain enough evidence to judge a skill, iQuantize reports nothing for it rather than a confident guess. A groove with no dynamics in it produces no dynamics score; a take where the notes fell apart will not pretend to grade your timing.
An honest blank is worth more than a plausible number, because you are going to spend an evening acting on whatever it tells you.
Find out what your playing actually looks like
Connect your kit and play one take. You get a verdict, the bars that went wrong, and the one thing to fix next.
Requires an electronic drum kit or a MIDI-capable drum module.
What we deliberately do not do
Every one of these is a choice, and each one is the reason the app works the way it does.
You get told you passed only when you actually did
iQuantize does celebrate. There is a day streak for turning up, and a moment when you clear a groove. What there is not is a points economy, a level ladder or a leaderboard — because those pay out for playing, and playing is not the same as playing well.
Clearing a groove here means every skill that groove was written to test has met its own pass mark. Not an average that a strong backbeat can drag over the line, and not a participation tick: a skill the app could not measure honestly does not quietly count as a pass. You cannot grind your way through it, and you cannot get there by turning up.
That is the whole difference. A reward for the session tells you that you played. A reward gated on seven measurements tells you that you improved — and it is worth something precisely because it can be withheld.
A graded curriculum, not a content firehose
The library is deliberately smaller than a catalog and deliberately ordered. It is informed by drum method books, graded exam paths and teaching sequences, and each groove introduces exactly one new element — ghost notes, an open hi-hat, a syncopated kick, a shuffle feel.
Thousands of lessons sounds like value until you are the one choosing between them. Choosing badly is the most common way self-taught players stall, so iQuantize takes the choice away and spends its effort on knowing what you should play next.
Native on Apple, and that is a feature
iQuantize is one native codebase for iPhone, iPad and Mac, talking straight to CoreMIDI with hardware timestamps on every note. There is no browser layer and no cross-platform runtime between your kit and the scoring.
When the product is timing measured in milliseconds, the stack it runs on is not an implementation detail. It also works fully offline, with no account, no email and no password.
Where Drumeo is the better buy
- Actual teaching. Drumeo has world-class instructors covering technique, styles and musicality that iQuantize does not attempt to teach.
- Any kit, or none. Acoustic drummers get the full value; iQuantize needs a module that sends MIDI.
What iQuantize costs. 14-day free trial. Pro's planned launch price is €14.99 a month or €120 a year (save 33%), VAT included. A free tier keeps the Starter grooves after the trial. See the full breakdown.
Common questions
Should I cancel Drumeo and use iQuantize?
If you are still learning technique and repertoire, no — keep being taught. What no video can do is tell you whether the thing you drilled all week actually changed your playing, and that is the gap most self-taught drummers stall in. Watching is how you learn what to do; measuring is how you find out whether you are doing it.
Does iQuantize teach technique?
No. There is a notation guide and each groove introduces one new element, but there is no instruction on grip, posture or how to execute a rudiment. It measures and prescribes; it does not demonstrate.
I have an acoustic kit. Is iQuantize any use?
Only with triggers and a module that outputs MIDI. Without MIDI there is nothing to analyse.
