Overview
f.lux
f.lux is a display management tool designed to align your screen's brightness and color with your internal biological clock. During the day, your screens look like sunlight, but as the sun sets, the software automatically transitions your display to a warmer, amber hue. This shift mimics indoor lighting and reduces the blue light exposure that often interferes with your sleep patterns and causes digital eye strain.
You can customize the experience by telling the software exactly what kind of lighting you have and where you live. It then handles the transitions automatically, so you never have to manually adjust your monitor settings as evening approaches. It is a set-it-and-forget-it solution for anyone who spends long hours in front of a computer, especially during late-night sessions.
RightFont
RightFont is a lightweight font manager designed to simplify how you handle typography on your Mac. You can instantly preview any font without installing it, making it easy to find the perfect typeface for your creative projects. The software integrates directly with your favorite design tools, allowing you to activate fonts with a single click and keep your workspace clean.
You can organize your collection into custom font sets or use smart filters to group fonts by category, weight, or width. It also supports seamless synchronization through cloud services like Dropbox or Google Drive, ensuring your team always uses the correct versions of every font. Whether you are a solo freelancer or part of a large creative agency, it removes the friction of manual font installation and organization.
