Field Guide: Sketch Journal

Field Guide turns your iPhone into a sketchbook that opens like a real one. Unfold iPhone Duo and you get two pages: your drawing on the right, and everything that helps you draw it on the left. Fold it shut and the cover closes on your work. MADE FOR THE FOLD • Keep a reference photo, live camera, your last page or field notes on the left page • Drag photos and stickers across the fold to copy them • Half-fold the phone like a tent to show your sketch to someone across the table • Play the drawing game together, one of you on each side • Close the phone and the book closes too A SKETCHBOOK THAT FEELS LIKE PAPER • Pen, pencil, marker and chalk, with any ink color • Paper colors and patterns • Pages that turn and curl under your finger • Two-finger tap to undo, three-finger tap to redo KEEP MORE THAN DRAWINGS • Add photos and short videos with frames and color looks • Stickers and washi tape • Voice notes, weather and field notes on every page • Replay a sketch stroke by stroke, and share it as a video YOURS, AND ONLY YOURS No account, no ads and no tracking. Your notebooks stay on your devices and in your own iCloud, where only you can see them. Field Guide works on any iPhone or iPad running iOS 26 or later, and it's at its best on iPhone Duo.
