Screen Test v1.1 — Native macOS monitor diagnostic tool with 25+ tests (dead pixel, motion blur, uniformity, etc.)

Problem:

This app was originally created because of a request from a Reddit user. He didn’t like using web-based monitor testing tools and wanted a native macOS app that could work completely offline. When buying a new monitor or troubleshooting display issues, Screen Test makes it easy to quickly check for dead pixels, backlight bleeding, sharpness, and other display problems anytime.

Comparison:

Online Monitor Test and other browser-based tools require an internet connection, may load slowly, and lack a native macOS experience. Screen Test launches instantly, works fully offline, and provides exclusive tools that web-based testers don’t offer, such as dynamic motion blur/ghosting tests, text resolution charts, and customizable sharpness text for more precise display calibration.

Changelog: V1.1 is now available with 7 new test tools including Dead Pixel cycle, Motion Blur, Custom Color fill, Checkerboard contrast, Gray Steps, Text Resolution chart, and Sharpness text editing.

Pricing: Lifetime Access: $3.99

Most Screen Test features are available for free, with only a small number of advanced options requiring an unlock. The $3.99 lifetime access helps support ongoing development, while all core monitor testing features remain free to use.
