2. Creating a Side-by-Side Photo Using the Shortcuts App

One of the simplest ways to compare two pictures on your iPhone is by using the Apple Shortcuts app. This method allows you to create a custom shortcut that combines two images side-by-side without needing a third-party application.

2.1. Installing the Shortcuts App

If you don’t already have the Shortcuts app installed, download it for free from the App Store. The app is a native Apple product, ensuring compatibility and security.

2.2. Creating a New Shortcut

1. Open the Shortcuts App: Launch the Shortcuts app on your iPhone.
2. Tap the “+” Icon: This will start a new shortcut.
3. Add Actions: Use the search bar to find and add the necessary actions.

2.3. Adding Actions to Your Shortcut

Here’s a step-by-step guide to adding the required actions:

1. Select Photos:
   • Search for “Select Photos” and add it to your shortcut. This action will prompt you to choose the images you want to compare.
   • Enable “Select Multiple” to pick two photos at once.
2. Get Details of Images:
   • Search for “Get Details of Images” and add it.
   • Set it to get the Width and Height of the images to determine which one is wider.
3. Calculate Aspect Ratio:
   • Add a “Calculate” action to calculate the aspect ratio.
   • For the first image, the formula is “Width / Height.”
   • Repeat for the second image.
4. Determine Orientation:
   • Add an “If” condition to check which image is wider.
   • If Image 1’s aspect ratio is greater than Image 2’s, it’s wider.
5. Combine Images Based on Orientation:
   • Inside the “If” condition (Image 1 is wider):
     • Add a “Combine Images Horizontally” action.
     • Set the Spacing to “None.”
   • Otherwise (Image 2 is wider):
     • Add a “Combine Images Vertically” action.
     • Set the Spacing to “None.”
6. Save to Photo Album:
   • Add a “Save to Photo Album” action to save the combined image to your Photos app.

2.4. Naming and Customizing Your Shortcut

1. Name Your Shortcut: Tap the name at the top and give your shortcut a descriptive name like “Combine Side-by-Side.”
2. Change the Icon: Customize the icon and color to make it easily recognizable.
