One Stroker

One Stroker is a simple scoring app where you draw shapes in one stroke and receive a score based on beauty and accuracy. Choose from circles, triangles, squares, stars, hexagons, and hearts, then draw the shape with your finger in one smooth stroke. When you lift your finger, your drawing is scored automatically.

The scoring system checks not only how similar your drawing looks, but also the features that make each shape recognizable. It evaluates straight lines, corner count, side balance, aspect ratio, star peaks and valleys, heart shape, and more. After scoring, the correct neon shape appears over your drawing so you can intuitively see where your line matched and where it shifted.

Main features: ・ Draw shapes in one stroke ・ Score out of 100.0 with one decimal place ・ View shape-by-shape local records ・ Game Center leaderboards and achievements ・ Simple, modern neon-inspired design

A quick, simple, and surprisingly deep one-stroke challenge. Draw a beautiful line and aim for a perfect 100.0.
