Most mobile apps are designed for phones first. Then someone opens the app on a tablet, and the result is a phone layout stretched across a large screen: long lines of text, huge buttons, empty space everywhere. Store reviewers and users both notice.

The first decision is whether tablets matter at all. For some products they are rare. For others they are the main device: in retail stores, on factory floors, in clinics, in restaurants, in schools and at home in the evening. Usage data from an existing app or website answers this better than assumptions.

If tablets matter, the goal is an adaptive layout, not a second design. The same screens rearrange based on available width. A list and its detail view sit side by side instead of on separate screens. Forms use two columns. Navigation moves from a bottom bar to a side rail.

Both major platforms support this. Android uses window size classes to describe compact, medium and expanded widths. iOS uses size classes and split view controllers. Cross platform frameworks offer similar tools. The work is in designing a few breakpoints carefully and testing them, not in writing separate code.

Orientation adds another case. Tablets are often used in landscape, sometimes on a stand. Screens that assume portrait break in obvious ways: cut off buttons, keyboards covering fields, charts squeezed into a thin strip.

Multitasking matters too. On both platforms, an app can run in part of the screen next to another app. It may be given a width close to a phone, then resized while in use. Layouts must respond to changes in window size, whatever the device.

Input differs. Tablets are often used with a keyboard, a trackpad or a stylus. Keyboard shortcuts, hover states and pointer support make a tablet app feel native. Without them, users with a keyboard find they must still tap everything.

Store listings need tablet screenshots, and both stores feature apps that support large screens properly. Poor tablet support can lower ratings from exactly the users who spend the most time in the app.

Test on real devices, including the cheaper tablets people actually own. Emulators are useful for layout but miss performance and touch problems.

Plan tablet support at the design stage. Adding it after launch usually means reworking navigation and many screens. Designing a few flexible layouts from the start costs far less.

Foldable phones make this more pressing. A single device can switch between a narrow screen and something close to a small tablet while the app is open. Apps that handle window size properly work on foldables with little extra effort. Apps that assume a fixed phone layout either stretch awkwardly or restart and lose the place the user had reached.

Content density is a design decision. A larger screen should show more useful information, not the same content with bigger margins. A tablet version of a dashboard can show several charts at once. A tablet reader can show a table of contents beside the text. Deciding what to add at each width is where most of the design effort goes.

Analytics should separate phone and tablet sessions. Crash rates, conversion and time in app often differ, and problems on tablets can hide inside overall figures. Tracking by window size class as well as device model shows where the layout needs more work.

Drag and drop is another expectation on tablets. Users want to move an image from one app into another, or reorder items in a list with a finger or a pointer. Both platforms support this, but it needs explicit design and testing for each screen where it makes sense.

Performance on older tablets is worth a check as well. Many tablets stay in use far longer than phones, often shared by a family or mounted on a counter in a shop. An app that runs smoothly on a new phone can struggle on a tablet that is several years old, especially when a larger layout loads more content at once.

Keyboard focus needs its own review. When a hardware keyboard is attached, the tab key should move through fields in a sensible order, and the focused element should be clearly visible. Screen reader users on tablets rely on the same structure, so this work improves accessibility at the same time.
