Color Blind Test

Color Blind Test appears to be a mobile medical app focused on color vision screening. Based on the title and short description, it is commonly used to check for possible color vision deficiencies using an Ishihara-style test format, which is a familiar type of pattern-based color perception check. It may be useful for quick self-checks on a phone when someone wants a simple way to look at how they distinguish colors.

Because it lists internet and network-related permissions, the app may also support online content, service updates, or connected features beyond the basic screening flow. The foreground service and wake lock permissions suggest it may keep the app active during a test or while delivering background tasks. As a phone app in the Medical category, it seems aimed at personal use rather than professional diagnosis, so results would commonly be used as a rough screening reference instead of a full eye exam.
