What's New in Resolutioner

2.1

October 1, 2026

Resolutioner is now ready for iOS 27 and macOS 27! I also have a few new features for you! WHAT’S NEW - Calculate Aspect Ratio: if you input a resolution to scale up/down, you can now calculate its base aspect ratio. For example, 1920 × 1080 would be 16:9. - Visualize Resolution: now you can view your input resolution as a rectangle to get an idea for what it would look like! - Shortcuts support! Use Resolutioner features within your Shortcuts, or manage your Saved Presets within Shortcuts. - Updated all app icons to look their best with the new Liquid Glass icon rendering! - Improved Mac Menu Bar app (now a popup window). BUG FIXES - Fixed and improved some animations - Fixed “Quit Resolutioner” SF Symbol - Fixed some spacing issues - Multiple UI fixes and improvements

FAQ

What does Resolutioner do?

Resolutioner is a utility app designed to help you calculate and scale screen resolutions. 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?

Yes, you can save any resolution you calculate or create as a preset. Simply tap 'Add Preset' and give it a custom name. These saved presets can be edited at any time, making it convenient to access your preferred resolutions quickly.

Is Resolutioner free to use?

The application is free to download and use, with options for in-app purchases. This model allows users to try out the core functionality before deciding to invest in additional features or content.

What devices is Resolutioner compatible with?

Resolutioner supports a range of Apple devices, including iPhone, iPad, and Mac. All your saved resolution presets can be synced across these devices using iCloud, ensuring consistency and accessibility no matter which device you are using.
