ELlipser
Ellipse Analysis
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Measure bloodstain or bullet trajectory ellipses on photos. Set scale, define plumb, fit the stain, and read α, γ, V, and H. Save annotated images for your case file.
ELlipser is a professional tool for bloodstain or bullet impact ellips analysis. Import a scene or evidence photo, establish scale and vertical reference, fit an ellipse to a bloodstain, and read the measurements and angles used in impact and directionality analysis — all on your iPhone or iPad.
Built for forensic practitioners, crime scene investigators, and students who need a fast, field-ready alternative to desktop analysis workflows.
HOW IT WORKS
1. Import — Load a photo from your camera roll.
2. Scale — Mark two points on a known distance and enter the real-world measurement (m, cm, mm, in, or ft).
3. Plumb — Define a vertical reference line when the image is not perfectly upright.
4. Ellipse — Fit an ellipse to the stain using intuitive on-screen controls. Adjust length, width, position, and rotation with precision.
5. Read — View live readouts for length, width, alpha (α), gamma (γ), vertical angle (V), horizontal angle (H), and ellipse center coordinates.
6. Save — Export an annotated image or full screen capture to Photos for reports and case documentation.
