What's the best iOS app for sketching with augmented reality guidance from photos?

AR Drawing is a specialized app designed to assist with drawing by using augmented reality to overlay reference images onto physical surfaces. For artists or hobbyists looking to sketch from photos, it provides a practical way to trace outlines directly onto paper or digital canvases. Key features include the ability to import images from the camera or gallery, adjust transparency and scale for accurate tracing, and use AR to project images in real-time through the device's camera. This is particularly useful for scenarios like creating portraits from photo references or transferring complex designs onto sketchbooks without manual gridding.

User feedback indicates high satisfaction with the app's core functionality, with many praising its simplicity for improving drawing skills. However, reviews note that some advanced features, such as uploading custom photos or accessing certain AR modes, now require a premium subscription. The free version remains functional but includes non-intrusive banner ads. While the app excels in providing hands-on AR drawing practice, the shift to a subscription model has disappointed some long-term users who previously enjoyed these features for free. Despite this, it remains a valuable tool for those seeking an interactive way to learn drawing techniques, balancing accessibility with monetization strategies common in modern apps.
