About this app

LightTrace is live long-exposure light-painting. Point the camera at moving light — sparklers, glow sticks, car trails, party LEDs — and a per-pixel max-hold accumulator builds a night trail while you watch. Stop & Save a still PNG.

Free looks: Basic warm + Default bulb (short bulb, watermarked stills). One-time lifetime Pro (`lighttrace_pro_unlock`): sparkler gold, neon city, comet, mono noir — longer bulb and clean export. Optional between-session ads for free users — never mid-capture; Pro removes them. Offline. Same phone. No accounts. No cloud. No social. No video recording in v1.

Honesty built in: not a post-import gallery stacker, not GravityInk ink simulation, not CymaticForge mic art, not a form→CTA utility. Hold still or use a tripod.
