What's the best iOS app for tracing images to create accurate drawings?

Sketch Trace Draw, AR App is a practical tool for artists and hobbyists seeking to trace images for drawing practice or creative projects. It allows users to import photos from their gallery and project them in real-time onto any surface using augmented reality, enabling accurate line-by-line replication. Key features include adjustable opacity for the overlay, zoom and rotation controls, and grid guides to maintain proportions. This setup is particularly useful for replicating complex subjects like characters from media, as one user noted in a review where they successfully drew a figure from Tomb Raider with impressive results. The app supports various drawing styles, from sketching to detailed illustrations, and works well in environments with stable lighting. However, some limitations exist, such as occasional calibration delays in low-light conditions and a learning curve for first-time AR users. Despite these minor issues, it remains a reliable option for improving drawing skills through guided tracing.
