Once upon a time, it might have been acceptable to just offer one (phone) sized app for use on both smartphones and tablets. Those days are long gone. Tablets have clearly caught on with the general public and developers have had plenty of time to create tablet-optimized apps. If you’re still struggling with this newer medium, check out the handy Tablet App Quality Checklist created by Google.

Focused on tablet-specific quality, feature set and UI, Google breaks the checklist down into 10 categories – each with its own mini checklist and set of considerations:

• Test for core app quality
• Optimize your layouts for larger screens
• Take advantage of extra screen area available on tablets
• Use icons and other assets that are designed for tablet screens
• Adjust font sizes and touch targets for tablet screens
• Adjust sizes of home screen widgets for tablet screens
• Offer the app’s full feature set to tablet users
• Don’t require hardware features that might not be available on tablets
• Declare support for tablet screen configurations
• Follow best practices for publishing

While the list is obviously geared toward Android tablets, its points are generic enough to be applied to apps for any tablet. So don’t just port your phone app to a bigger screen, take the time to read the Tablet App Quality Checklist and really optimize your tablet app.
