Genie Strings
String Portrait Template
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Turn any photo into string art. Genie Strings generates your nail sequence and a to-scale nail layout PDF — ready to string, ready to hang.
Transform any photo into stunning string art with AI enabled app Genie Strings — the most complete string portrait generator available. Whether you are creating a gift, a wall piece, or a craft project, Genie Strings calculates every thread path for you and delivers a precise nail-by-nail guide ready to follow.
Three Portrait Modes
Choose from Monochrome (single black thread), Greyscale (black and white for richer tones), or Color (up to 8 thread colours from the CMYK and RGB palette). Every mode produces a professional result from any photo.
Smart Image Editor
Prepare your photo before rendering with built-in brightness, contrast, sharpness, and saturation controls. Remove the background in one tap using on-device machine learning, then set a custom background colour with the HSV colour wheel. Pinch and drag to position your image precisely within the board frame before generating.
Three Board Shapes
Circle, Square, and Rectangle boards are all supported. Enter your board dimensions and nail spacing in centimetres and the app calculates the exact nail count automatically. Portrait and landscape orientations are both available for rectangle boards.
Advanced Monochrome Controls
Four precision controls give you complete creative command: Darkness sets overall portrait depth, Person Focus concentrates thread on dark areas, Shadow Richness layers depth into hair and shadows, and Fine Detail captures subtle mid-tones. The app analyses your photo and suggests starting values automatically.
Nail Layout PDF
Every purchase includes a to-scale nail layout PDF showing your board shape with every nail numbered and positioned exactly. Print at Actual Size and use it directly as your drilling or pinning guide — no measuring required.
Step-by-Step Thread Instructions
Your nail sequence is exported as a text file with clear colour-change instructions. Use it alongside the Genie Reader companion app to have your instructions read aloud while you string, keeping your hands free throughout the process.
My Templates
Every exported template and nail layout PDF is saved locally and in iCloud, accessible from My Templates at any time for resharing or reprinting.
Genie Strings for iPhone and iPad is here — the full string art generation experience on iOS.
The complete weaving engine brings accurate string art rendering across all three portrait modes and all three board shapes. The image editor includes background removal, a custom colour wheel, and full adjustment controls. The pan and zoom canvas lets you frame your subject precisely before rendering.
Monochrome mode includes four advanced controls — Darkness, Person Focus, Shadow Richness, and Fine Detail — with automatic value suggestions based on your photo.
After rendering, the Adjust and Re-Render button lets you tweak any setting and regenerate instantly. The pencil button on the source canvas reopens the editor at any time without losing your settings or dimensions.
Every export now includes both the nail sequence text file and a to-scale nail layout PDF with every nail numbered. Both files are saved locally and in iCloud and appear in My Templates.
A full in-app instructions guide covers the complete workflow, nail numbering conventions, monochrome tips, and quick-start settings for different skin tones and photo types.
Performance is optimised for long renders — the engine runs on a background thread with a serial pixel buffer to keep the UI smooth and stable throughout.
