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 waiting, no processing spinner.
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 pixels are 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 do not 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

A FEW HONEST NOTES
Long exposure is a real photographic technique, and it behaves like one:
• It wants darkness. Bright moving light against a dark scene is what makes a trail. 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, a bag — anything solid.
• It wants a few seconds. A car crossing the frame takes time.
Get those three right and the results are the kind of photograph people stop scrolling for.
Watch light paint itself. Live long exposure, made on your phone.
