Resolutioner is a simple utility app for calculating resolutions, aspect ratios, and saving resolutions for future reference.


The resolution calculator helps you to calculate a resolution by filling in the other side, according to your set ratio. Editing the set ratio is as simple as a tap, too. When choosing your scale, you can either put in a standard fraction like 16:9, or put in a resolution you want to scale up or down while keeping the same aspect.


And when you've got a resolution you want to save, just tap Add Preset to save it with a custom name. You can edit your presets at any time.


Resolutioner supports iPhone, iPad, and Mac. All of your saved presets sync over iCloud, too.

Available on iPhone, iPad, iPod touch, Apple Watch, and Mac. Requires iOS 14, iPadOS 14, or macOS Big Sur (11.0) or later.
