About this application

Blink Comparison is an Android application for visual comparison of photographs, with a focus on tamper-evident seals. It helps a user inspect two images by switching between them in place, so that small changes in a seal, label, wire, or surrounding detail can be noticed by eye. The program does not replace a measurement tool or an automated forensic check; its purpose is to make human visual inspection more convenient.

The application is published by Yaroslav Pronin and is distributed under the GPL-3.0-or-later license. Its stated platform is Android, so it is intended for use on phones or tablets rather than as a desktop image comparison program. It is suited to workflows where a reference photo and a later photo must be compared quickly on the device.
