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). 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 s…
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 14 screenshots above are Resolutioner's answers to those questions — they're public, they're real, and they made it through Apple's review.

The accent colour we picked up, #D4644C, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
