50 tracing guides: animals, nature, objects, and shapes. Draw one half, close your iPhone Duo, and unfold your mirrored picture.
Requires iPhone Duo with iOS 27.1 or later for drawing.
Turn a few strokes into a symmetrical picture with the fold of your iPhone Duo. Draw on one half of the open inner screen, close your Duo completely, then open it to reveal the mirrored imprint. Add more strokes and fold again to build your picture.
Choose your drawing side and explore:
• Five coordinated palettes, each with four colors plus graphite.
• Four paper styles: smooth white, cream sketch paper, graph paper, and kraft paper.
• 50 optional tracing guides, grouped into animals, nature, objects, and shapes. Previews show only the dashed template half. The guides stay out of your exported picture.
• Three brush widths and three eraser sizes.
Erase either half independently and undo drawing, erasing, or imprint actions. Your current page saves automatically on your device, so you can continue later.
Save a PNG with your chosen paper or a transparent background. Add it to Photos or share it with the apps you use, then keep drawing.
All drawing features are free. No ads, subscriptions, account, or tracking. Drawing works offline. Optional, repeatable support purchases help with the development and care of small, ad-free apps without unlocking extra features.
On other iPhone models, FoldSketch explains the device requirement and keeps settings and support available.
