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 5-session warm-up, so your first clumsy sessions do 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 weighted parts. The parts are always shown to you — there is no single number hiding how it was made.

Line Quality
How good your stroke is as a line, wherever you drew it: straight, steady and in one pass. Shaking, curving, loops and going back over it cost points. Under 60, the other scores (except Line Quality) count only in part.
Circles call it Circle Quality. Traced circles and curves have no Guide Accuracy yet: their Guide Fit, Roundness and Curve Fit judge the shape and its closeness to the guide together.Guide Accuracy
How close your stroke stays to the dashed guide between the two points, and how much of it you cover. Running past an end point is left to End Accuracy.
Line drills only, for now.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
How quickly you draw the stroke: full marks from 0.25 to 0.9 seconds, none from 2.3 seconds. Under 60, the other scores (except Line Quality) count only in part: accuracy you get by drawing slowly is not the skill these drills build.
Circles have their own time band: full marks from 0.3 to 1.5 seconds. Curves also count how even your speed is.Why pace is in there at all
A stroke drawn between 250ms and 900ms scores full marks for pace. Below 60, the other parts count only in part: hitting the targets by drawing slowly is the habit the drills are here to break.
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 89 points.

Drawn from the shoulder in 0.6 seconds. It misses the end target by more, but the line itself is clean and steady — and that is what Line Quality measures.
The drill library
7 playable now, 1 on the way. Each drill keeps its own history, records and trophies.
Straight-Line

Traced Ellipse
Trace tilted ellipses of varying size and shape.
Boxed Circle
Draw a circle inside a box, touching all four side dots.
C-Curve
Trace an even C-curve in one smooth stroke (the C of CSI).
S-Curve
Trace a flowing S-curve that bends one way, then the other.
Vanishing Point
Fire lines that converge on a vanishing point by eye.

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 ten 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.
