Drawn from the wrist over 2.4 seconds, correcting along the way. The endpoints are nearly perfect — and it still scores lower.
Are you actually getting better at drawing?
DrawTrainer scores every stroke you draw against the target it was aiming for, so practice produces a number instead of a feeling. Free, no account, nothing to install.
Start Practicing20 strokes per session — about two minutes.How it works
One session is 20 attempts at a single drill. There is no stopping between attempts unless you want to.
1
Pick a drill
7 drills covering straight lines, circles, ellipses and curves. Each one targets a different fundamental and is scored on its own terms.
2
Draw 20 reps
One stroke per rep against a fresh target. The score appears the instant you lift the pen, broken into the parts it was built from.
3
See whether you improved
The session average joins your progress chart. Beat one of your own top-three marks and you keep a trophy for it — after a 10-session warm-up, so your first clumsy week does not set the bar.
What it costs, and where your work lives
What is free, what may cost money later, and where your work is kept.
Free, and what is free stays free
All 7 drills, your complete history and every trophy. No account, no email, no ads, and nothing about you is sold or shared to anyone.
One paid thing is planned: an optional account that backs your practice record up off this device and syncs it between them. It does not exist yet and the price is not set.
The commitment that is already firm: nothing that is free today will become paid later. These 7 drills and every score you have already made stay free permanently. A genuinely new drill built after this may be part of the paid account — but it would be an addition, never something taken away from you.
Your history lives in this browser
Only in this browser. Clearing your site data, switching to another browser, using a different device or drawing in a private window all start you from zero, and there is no copy anywhere to restore from.
That is the real limitation of a free app with no account, and it is exactly the problem the paid account above would solve. Worth knowing before you put twenty sessions into it.
What the score actually measures
Every attempt is scored 0–100 from three weighted parts. The parts are always shown to you — there is no single number hiding how it was made.

Line Quality
How close your stroke stays to the ideal straight line. Lower deviation = higher score.
Circles call this Evenness or Roundness; curves call it Curve Fit.Endpoint accuracy
How close your first and last points land on the two targets. Shown to you as Start Accuracy and End Accuracy.
Circles call these Completeness (how much of the loop you covered) and Closure (how near it returns).Pace
Combines stroke speed (ideal: 250–900ms) and speed consistency throughout the stroke.
Circles call this Smoothness.Why pace is in there at all
A stroke drawn between 250ms and 900ms scores full marks for pace. Slower strokes wobble, so hesitating costs you twice.
Diagonal Short weights pace at 60% — that drill is about speed.The same target, drawn two ways
Both strokes below were run through the same scoring code the app uses. The careful one lands almost exactly on both targets and still loses by 18 points.
One confident stroke

- Line Quality78

- End Accuracy86
- Pace97
Drawn from the shoulder in 0.6 seconds. It overshoots the end target by more, but the line itself is far straighter — and Line Quality is 60% of the score.

Do I need a stylus?
No. Mouse, trackpad, touch and pen all work. DrawTrainer records which one you used so a mouse score is never silently compared against a pen score.
How long before the numbers mean anything?
One session gives you a baseline. Roughly 10 sessions is where the trend line starts telling you something a feeling could not.
Two minutes gives you a number.
Twenty sessions gives you an answer.
