## What is Sketchthru?

Sketchthru turns your phone into a drawing projector. Pick a photo, prop your phone over real paper, and trace what you see on screen with a real pencil.

The camera shows your paper live while your reference photo floats on top at the opacity you choose. Line up your shot, lock it in place, and start drawing. Smart Lock uses AR to keep the overlay glued to your paper even if your phone shifts.

HOW IT WORKS
1. Pick a photo you love
2. Prop your phone over your paper
3. Trace what you see on screen

DRAW ANYTHING, ONTO ANYTHING
A sketchbook, a canvas, a greeting card, a wall. If your camera can see it, you can trace onto it.

EVERYTHING YOU NEED TO TRACE
- Sample gallery to get you started
- Opacity slider so you can see paper and photo at once
- Pinch, drag and twist to place your photo, or drag the corners to resize it
- Nudge the camera view instead of the picture when that lines up faster
- Rule of thirds grid and flip tool
- Undo and redo for every adjustment
- Press and hold to peek at your drawing

RECORD YOUR PROCESS
Record while you draw and Sketchthru turns hours of sketching into a shareable timelapse. Start and stop from the volume button or your Apple Watch so you never knock the phone out of line, and keep an eye on the take from your Lock Screen.

GO PRO
- Upload photos from your camera roll
- Edges and Posterize filters turn any photo into clean line art, ready to ink and paint inside
- Subject filter lifts your subject off its background
- Strobe mode blinks the overlay to check your lines
- Timelapse in crisp 1080p without a watermark
- Unlimited saved traces

ALSO INCLUDED
- Share a photo straight into Sketchthru from any app
- Home Screen and Lock Screen widgets for your last session and your drawing streak
- Ask Siri to start a trace or start recording

Sketchthru is made for beginners, doodlers, and anyone who wants to put real pencil to real paper. No account needed. Start tracing in under a minute.
