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. DESIGNED FOR iOS AND iPadOS Resolutioner has been designed with Liquid Glass in mind, and works great across iPhone, iPad, Mac, and Apple Vision Pro! - Full support for Dark, Tinted, and Clear Home Screen modes - Full multitasking support: multi-window support, keyboard shortcuts, full cursor support, Slide Over + Split View, and more - Choose from five app icon designs - Fully updated for Liquid Glass - iCloud sync support - Dynamic text support

Verdict
The clearest difference is price: O at Free against Resolutioner's $0.99. O also leads on update cadence (fortnightly vs every 33 months) and ratings volume (8.6K vs 946). Resolutioner's advantage is ads (none vs shown) and review sentiment (80% vs 63%). On rating, in-app purchases, monetization model and chart position there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
O is free to download; Resolutioner costs $0.99 up front. Resolutioner sells 5 one-off in-app purchases and O sells 23 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.5 for Resolutioner against 4.5 for O. That said, the two scores are not equally well evidenced: O has 8.6K ratings behind it against 946, so its average is the more settled of the two. Written reviews are what separate them: 80% of Resolutioner's written reviews are positive against 63% of O's.
Resolutioner ships an update every 33 months, O fortnightly. The most recent releases landed on October 18, 2026 and October 20, 2026 respectively.
