POWERUP
The flight app for a paper plane that really flies, phone as cockpit, tilt to steer, and a tuning bay for pilots who fiddle.
PowerUp 4.0 clips a twin-motor flight computer onto a folded sheet of paper: under 20 grams, 20 mph, 230 feet of range on a ten-minute charge. The phone is the cockpit, and you fly by tilting it, eyes on the sky rather than the screen.
So the HUD has one rule: nothing decorative inside the pilot’s glance. A cyan throttle ring anchors the thumb, telemetry sits in the corners as arcs rather than numbers to read, and the horizon is the background instead of a widget. Landscape by default, because that is how you hold a controller.
The Hangar holds the approved airframes. The tuning bay holds everything a tinkerer wants within reach, trim, autopilot assist, bank limits, and the acro mode that throws loops and barrel rolls, kept deliberately dense and mechanical so it reads as instrumentation rather than settings.
Outcome
Shipped as the flight app for PowerUp 4.0, the cockpit and tuning bay are what pilots see every flight.
