Design a tattoo with AI, try it on a photo of your skin, and turn it into a clean stencil you can print at the exact size. Describe an idea or start from a reference photo. LineSpark takes it from first sketch to transfer-ready stencil in one app, for tattoo artists, apprentices, and anyone planning their next tattoo. DESIGN A TATTOO FROM AN IDEA • Describe your idea in a few words, or start from a suggestion • Pick a style: Fine line, Traditional, Japanese, Blackwork, Watercolor, Geometric, or Auto • Choose black and grey or color • Refine it with simple edit instructions and keep every version • Make a stencil from any design TRY IT ON YOUR SKIN • Place a design or stencil on a photo of your arm, leg, back, or chest • On arms and legs it lines up with the limb and can bend with its curve • Drag, pinch, and use the side handles to set the width and height • Flip it, adjust the ink, or see a design in black and grey • Keep it in Try-ons, save it to Photos, or share it FROM PHOTO TO CLEAN STENCIL • Import from Photos, Files, or Camera • Crop, rotate, mirror, and prepare the reference • Choose Clean Outline, Balanced, or Detailed Texture • Generate one or more stencil variations • Compare the stencil with the original photo • Preview it in purple, black, red, and other transfer ink colors REFINE EVERY DETAIL • Draw and erase directly on the stencil • Adjust line weight, darkness, threshold, and contrast • Pan, zoom, mirror, undo, and redo • Keep project versions organized for later comparison PRINT AT THE SIZE YOU NEED • Set physical dimensions in centimeters or inches • Prepare A4, Letter, Legal, and 8.5 × 14-inch layouts • Tile larger designs across multiple pages with overlap • Add registration marks and a 100 mm calibration line • Export PDF or PNG, share, or print with AirPrint CREDITS OR UNLIMITED Pay as you create with one-time credit packs, or choose LineSpark Unlimited, a weekly subscription for unlimited stencils, AI tattoo designs, and try-ons (fair use applies). Available plans may vary. Failed, timed-out, or rejected generations do not use credits. Placing and adjusting a try-on uses nothing; it is charged once, the first time you save or share it. Editing stencils, reopening projects, and exporting stencils do not use credits. LineSpark Unlimited renews automatically every week at the price shown in the app until you cancel. Payment is charged to your Apple ID. Cancel anytime in your Apple ID settings at least 24 hours before the end of the current period. YOUR DATA Selecting and preparing a reference does not upload it. Cloud generation sends the prepared image, instructions, and settings only after you consent. Try-ons are rendered on your device. When you finish or leave a try-on, the photo, the tattoo, and the result are uploaded to improve try-on quality; try-ons you don't keep are deleted within 90 days. App analytics events exclude your images, instructions, project names, and email. Design it. Try it on. Print the stencil.

Verdict
The clearest difference is price: LineSpark at Free against Slice's $4.99. LineSpark also leads on update cadence (every 5 days vs every 2 months). Slice's advantage is in-app purchases (none vs 3) and iOS requirement (15.6 vs 17.0). On ads and device support there is nothing between them.
