Resolutioner vs OneTap Preview Resizer

Resolutioner by Sun Apps is a simple utility app for calculating and scaling resolutions and aspect ratios. You can input an aspect ratio and calculate a resolution based on it, or you can input a resolution and scale it up or down. For quick reference, you can save an aspect ratio to your Saved Presets, and load it back into the calculator with just one tap. NO ADS OR PREMIUM FEATURES The price you see is the price you pay. There are no ads, premium features, subscriptions, or anything else. And since we don’t collect any data, there’s no data for us to sell! If you really love the app, you can donate via the Tip Jar option (that’s the in-app purchases the App Store shows). SHORTCUTS SUPPORT Resolutioner extends all of its functionality to the Shortcuts app, so you can calculate resolutions, scale resolutions, and determine aspect ratios in Shortcuts or with Siri AI. You can also view, create, and manage your Saved Presets. INTERFACE You can choose from two great interface options, Unified or Split. Unified puts the calculator and Saved Presets on one page, while Split puts them side-by-side or into tabs, depending on screen/window size. You can also turn the theme color on or off, as well as toggle between a monospaced and a standard font design.
