## Frequently asked questions about Resolutioner

### What does Resolutioner do?

It allows you to determine a missing resolution based on a set aspect ratio, or to scale an existing resolution up or down while maintaining its aspect ratio. You can also save frequently used resolutions as presets for future reference.

### How can I calculate resolutions with this app?

You can calculate resolutions by filling in one side of the resolution (e.g., width or height) and setting your desired aspect ratio. The app will then compute the corresponding other side. You can input standard fractions like 16:9 or use an existing resolution to define the ratio for scaling.

### Can I save my custom resolutions?
