Resolutioner: Professional Aspect Ratio Calculator and Resolution Management Tool

by Sun Apps, LLC

Resolutioner provides precise resolution and aspect ratio calculations for designers and content creators. The iOS app automatically calculates missing dimensions while maintaining aspect ratios and stores frequently used resolutions for quick access.

Detailed Review

Resolutioner by Sun Apps, LLC fills a specific niche in the utility app market by providing professional-grade resolution and aspect ratio calculations. The application addresses a common pain point for designers, video editors, and content creators who regularly work with dimensional calculations but lack specialized tools for this purpose. With a 4.5-star rating on the iOS App Store, the app has established itself as a reliable solution for technical calculations that many general-purpose calculator apps overlook. The core functionality revolves around its intelligent calculation engine that automatically determines missing dimensions based on established aspect ratios. Users can input standard ratios like 16:9 or 4:3, or define custom ratios by entering specific resolutions. The app's scaling feature allows professionals to maintain aspect consistency when resizing content across different platforms and formats. Unlike basic calculators, Resolutioner preserves calculation history and enables users to save frequently used resolutions, creating a personalized reference library for recurring projects. User experience benefits from a clean, minimalist interface that prioritizes functionality over decorative elements. The input system uses intuitive numeric keypads and ratio selectors, while the saved resolutions section employs a simple list-based organization. Real-world usage patterns show that graphic designers particularly value the ability to store project-specific dimensions like t-shirt sizes, screen specifications, and print dimensions, eliminating the need to repeatedly calculate standard measurements for common design tasks. User feedback consistently highlights the app's precision and specialized functionality. Trill Livin's April 2025 review notes that 'You'd be surprised by how few aspect ratio apps can do this,' emphasizing the app's unique capability to calculate missing dimensions automatically. Caden Woodworth's January 2023 review praises the organizational benefits, stating the app helps store 'tote bag sizes, t-shirt sizes, screen sizes' in one centralized location, addressing the challenge of remembering numerous dimensions across different projects. The application demonstrates notable strengths in its specialized calculation accuracy and organizational features, though it remains limited to resolution-specific tasks without broader mathematical capabilities. The interface, while functional, lacks advanced customization options or integration with other design tools. Resolutioner serves as an ideal solution for professionals requiring frequent, precise dimensional calculations but may prove unnecessary for users with occasional or basic calculation needs.

Key Features

  • Automatic dimension calculation that computes missing values based on established aspect ratios, eliminating manual mathematical operations
  • Custom ratio creation allowing users to define unique aspect ratios by inputting specific resolution pairs for specialized projects
  • Resolution storage system that saves frequently used dimensions for quick retrieval, reducing repetitive calculation time
  • Scaling functionality that maintains aspect consistency when resizing content across different platforms and output requirements

Needed an app where I could enter in a custom aspect ratio, enter in one of the dimensions, and have the other dimension calculated automatically. You'd be surprised by how few aspect ratio apps can do this. This one does. Perfect.

This app is perfect if you are in the graphic design profession! I can store all of my dimensions all in one app! Like tote bag sizes, t-shirt sizes, screen sizes, and the list goes on. My mind is constantly drifting with thoughts that I can’t remember everything, so it’s nice to have an app I can store everything in after doing a quick units-to-points conversion (and I have an app for that too). I don’t have to look up anything; I have one app for everything, and offline too! So if you don’t have good internet, or always on the go, you can count on this app to save the day! *However, there is one more thing I would add to make it 100% perfect. It would be nice if I could drag my presets around so that organization could be better. Like I have device screen sizes mixed in with shirt designs, and mixed in with other stuff. It throws my OCD around, so it would be great if I could keep my presets organized a little better. Other then that, I would 100% download this app and I will consider donating when I have some spare change in the future! Keep up the great work, and good luck in college (the developer)!
