LaserTrail
Trajectories from Photographs
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
For CSI & forensic teams: align laser trajectories across photo sequences, preview a continuous trajectory, export for reports. 7 days free access.
LaserTrail helps crime scene investigators and forensic teams turn a series of photographs into a clear, repeatable record of a laser’s path through an environment. Import your images, mark where the laser appears on each frame, review a smooth trajectory that connects those points, and export a professional visual for reports, briefings, training, or case documentation.
Why investigators use LaserTrail
Laser documentation often spans multiple photos taken from different positions or moments. LaserTrail keeps that work organized in one place: a dedicated reference (base) image, aligned laser-dot marks on related frames, and a trajectory preview you can refine before sharing results.
How it works
Import — Bring in the images you need (up to many frames in one session).
Reference — Choose the base image that represents the scene context you want to anchor to.
Mark — Place precise marks where the laser dot appears on each laser frame.
Trajectory — See a smooth path through your marks so you can sanity-check continuity and geometry before export.
Export — Generate a composite image with the options you need—such as trajectory line, point markers, and optional pixel coordinate labels—so your output matches agency or lab standards.
Built for field-to-desk workflows
LaserTrail is designed for focused, low-distraction use on iPhone: high-contrast previews, pinch-to-zoom and pan on marking and trajectory screens, and double-tap to reset the canvas when you need a clean view. Your work stays on device under normal use (images and session data are stored locally on the phone).
