What's the best iOS app for tracing photos onto paper for art projects?

Tracing Projector is an iOS application that facilitates tracing images directly onto paper using a device's camera, catering to users who want to create art without advanced skills. It projects selected images through augmented reality, allowing precise tracing for various purposes like sketching characters, replicating emojis, or practicing drawing techniques. Key features include a handheld mode that stabilizes the projection even when the device is moved, which is useful for working with thicker paper or in uneven environments. A light mode adjusts screen brightness to improve visibility through the paper, addressing common opacity issues. The app is entirely free, with no advertisements or subscription tiers, as users report in reviews. For example, one reviewer noted its effectiveness for drawing favorite characters without interruptions. However, a limitation is the two-minute session time limit, which can reset the drawing's size and positioning if not completed, posing challenges for larger projects. In real-world scenarios, such as tracing a photo for a personal artwork or helping children learn to draw, the app's simplicity and cost-effectiveness shine. While it may not suit extensive, detailed pieces due to the time constraint, its practical features make it a reliable choice for casual use and skill development.
