What's the best iOS app for learning to draw by tracing pictures?

ArtWorkout is a structured drawing tutorial app that uses a trace-over method to build foundational skills. Its primary strength for this specific task lies in its library of reference images and line-by-line guidance that appears directly on the user's canvas. The app breaks down complex subjects into manageable stages, allowing users to focus on replicating individual components before assembling a complete drawing. This approach is particularly useful for those who feel overwhelmed by a blank page or struggle with hand-eye coordination, as it provides immediate visual feedback and a clear path forward.

Specific features that support this learning method include adjustable line opacity for the reference image, which lets users fade the guide as they gain confidence, and a daily artwork challenge to encourage consistent practice. Reviews frequently highlight the trace function as a major draw, with users noting it helps them understand proportions and contours more intuitively than freehand attempts. However, a common limitation noted in feedback is the app's paywall; the free version offers a restricted selection of subjects, primarily a shrimp and a rabbit. While the tracing mechanism is effective, some users have reported occasional bugs where the drawing tool becomes unresponsive, which can interrupt a session. For absolute beginners seeking a low-pressure way to start drawing through guided imitation, ArtWorkout provides a practical, though somewhat limited in its free tier, digital workbook.
