Sandbox Draw

Sandbox Draw turns your iPhone into a tray of soft, sunlit sand. Drag a finger and the surface carves into a real groove with a shadow along its low edge — not a painted-on line. Press harder for a deeper groove. Press hard enough and the device responds with continuous haptic feedback that tracks your stroke. Dig deep enough and a colorful pattern bleeds through from underneath, different every session. Tap the refresh button to smooth the sand flat and start over with a brand-new color world below. Tap the share button at any moment to save or send your drawing. Features - Real-time pressure-sensitive sand drawing, 120 Hz on ProMotion devices - Haptic feedback on the hardest presses - A surprise of color revealed at the bottom of every deep groove - One-tap refresh, one-tap share to Photos, Messages, AirDrop, and more - No accounts, no ads, no data collection A small, quiet app. Draw, smooth, draw again.
