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).
