Slow shutter camera: light trails, silky water & light painting, built live.
Your phone's camera takes one frame. TRAIL keeps them all. Point at moving light and hold. Headlights stretch into ribbons, a waterfall softens into silk, a torch waved in the air draws a glowing line — and you watch it build on screen while it happens. No processing screen, no waiting. NEW IN 1.2 • Long exposure from any video: pick a clip from your phone and watch it build • Self-timer (2, 5 or 10 s), so tapping the screen doesn't shake the shot • Duration presets that stop by themselves, or Bulb until you tap again • Pause and resume an exposure • Steady indicator, grid and level • Volume buttons and Bluetooth selfie remotes work as the shutter • Change brightness and look after the shot • Saves straight to your gallery (TRAIL album); shots taken sideways save upright • Now in 11 languages FIVE WAYS TO HOLD TIME • Light Trails: headlights, city traffic, anything bright that moves • Comet: trails that fade behind the light instead of staying forever • Silk: waterfalls, waves and clouds smoothed into one flow • Light Painting: draw in the air with a torch; only bright light is kept • Motion Art: soft ghosting for people and crowds in motion BUILT FOR LONG EXPOSURES • The exposure builds live on screen, frame by frame • Frames are stacked in high precision, so long exposures don't band or posterise • Automatic compensation when the camera's own exposure drifts mid-shot • Tail length and trail thickness controls • 8 colour looks • Save the build-up itself as a video • Frame in 3:4, 9:16 or 1:1 EVERYTHING STAYS ON YOUR PHONE Frames are processed on the device.

A FEW HONEST NOTES Long exposure is a real photographic technique, and it behaves like one: • It wants moving light. TRAIL stacks what moves; it does not brighten a dark scene the way a night mode does. • It wants darkness around the light. Pointing at a brightly lit room will wash out. That is the technique, not a fault. • It wants a steady phone. Rest it on a wall, a railing or a bag, or use a tripod; the timer keeps your tap out of the shot. • It wants a few seconds. A car crossing the frame takes time. Get those right and the results are the kind of photograph people stop scrolling for.
