ELlipser

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. KEY FEATURES • Pinch-to-zoom with center crosshair for accurate point placement • Real-world measurements when scale is set • Plumb line support for non-level photographs • Interactive ellipse controls with haptic feedback • Copy all readout values to the clipboard for reports • Adjustable text size, controller size, units, and decimal places • Optional tool tips to guide new users through each step • Save photo with overlay or full screen capture DESIGNED FOR THE FIELD Whether you are documenting a scene, reviewing evidence photos, or teaching BPA principles, ELlipser keeps the workflow simple: import, scale, plumb, fit, measure, export. No complex menus — just the tools you need for ellipse-based bloodstain analysis. SUBSCRIPTION ELlipser requires an annual subscription for full access after the beta period. Subscriptions are managed through your Apple ID and can be restored on any device signed in with the same account. IMPORTANT ELlipser is an analysis and measurement tool. Results depend on image quality, scale accuracy, and proper technique. It is intended to support professional judgment — not replace training, standard operating procedures, or qualified expert review.
