Draw anything from a photo. Underdrawing puts the picture of your choice over your camera so you can see it on your paper and trace it with a pencil. Importing your own photos, tracing and line art are free: no ads, no watermark, no time limit, and no subscription.
HOW IT WORKS • Pick a photo with the system picker, set your phone on a stand or a stack of books above your paper, and draw while you watch the screen • Move, resize and rotate the picture with your fingers, and flip it left to right or top to bottom • Slide the opacity until you can see both the picture and your paper • Lock the picture so it stops shifting while you draw, and nudge it into place with the arrow buttons
MAKE THE LINES EASY TO SEE • Line art turns a photo into clean outlines; adjust the detail and the strength until the lines show up on paper • Choose black, white, red or blue lines • A torch button for a dim room, and the screen stays on while you draw
PLAN YOUR PAPER • Grid method: choose A5, A4, A3, Letter, Legal or Tabloid, portrait or landscape • Underdrawing works out the size of every grid square in centimetres or inches and labels each one A1, B3 and so on
YOUR DRAWINGS STAY WITH YOU • Each drawing keeps its picture, position and settings, so you can come back to it tomorrow (your first three are free) • Underdrawing uses the system photo picker, so it only ever sees the photos you choose, never your whole library • No account, no ads and no tracking, and your photos and camera pictures never leave your device
UNDERDRAWING PRO: ONE PURCHASE, NO SUBSCRIPTION Pay once, keep it for good, and share it with your family: • Unlimited saved drawings • Time-lapse: Underdrawing films your drawing from the camera and turns it into a short video to save or share (no sound is recorded) • Shading guide that maps the darks, mid-tones and lights of a photo so you know where to shade • Custom paper sizes for the grid Importing photos, tracing, line art and the grid are always free.
Underdrawing needs your camera to show your paper behind the picture.
