Delta

On iPhone Duo

Delta 2.0 turns a half-folded Duo into a dual-screen handheld, one emulated screen per half. Close the phone and the emulated console goes to sleep, like the real thing.

Works in

• Tabletop

  Half-folded on a surface. Content on the upright half, controls on the half that lies flat.

• Fold action

  Opening or closing the phone is part of the app itself.
