iOS vs. Android App UI Design: The Complete Guide

If you’re designing both an iOS and an Android (Material Design) version of an app, this guide is your new best friend 😎.

We’re going to cover the most relevant differences between iOS and Android for UX/UI designers. If you’ve created an app on one platform, this is most of what you need to know to “translate” it for the other platform. But! – these are guidelines, and basically everything I’ll say is contradicted somewhere, even by Apple/Google themselves. This is about translating “iOS thinking” to “Android thinking” and vice versa.

Here’s what we’ll cover. Skip ahead, or read it straight through – like a freak. It’s your call.

iOS vs. Android UI Design: The Main Differences

Here are the most important differences that UX/UI designers need to take into account when “translating” an app from iOS to Android or vice versa:

Design element iOS Android
Minimum tap target size 44x44 pt 48x48 dp (What's a dp?)
Main app navigation Bottom nav Tabs at top of screen
Secondary app navigation Bottom nav “More” OR on-page UI Bottom nav OR "hamburger button" side menu
Primary button/action Top nav, right side Floating action button
Secondary actions On-page UI Top nav, right side
Single-choice lists List with checkmark for selected item Radio button list
Multiple-choice lists List with switches OR list with checkmarks for selected items Checkbox list OR list with switches
Confirm or allow undo of destructive actions Modal dialog to confirm choice Allow Undo via temporary on-screen notifications

Oh, and before we really dive in, let’s answer one important question that will frame everything else here…

Do I have to make my Android and iOS apps different?

Long story short: no.

Apple and Google are both very smart companies with a zillion users each. They will make UX mistakes like anyone else, but in general, when they define a design language for the default way in which their system should work, they’re not going to be making incredibly glaring mistakes. So while I present two ways of doing everything below (the iOS way and the Android way), neither is wrong. If your users are able to confidently navigate and use the app you’re creating, then no one can tell you not to use tabs on iOS or modal views on Android.

This article is written in the spirit of learning to “think in iOS” or “think in Android” – and if your goal is to make an app for both platforms, but have each feel native to the system it’s on, then this guide will be a huge help.

With that being said, let’s dive in.

Top-of-screen navigation

iOS vs Android nav UI differences

We’ll start from the top – literally. Each platform has different standards for what appears at the top of most screens.

On iOS, the (optional) left action is almost always some sort of “back” – whether to the previous screen sequentially (“Step 2” goes back to “Step “1), or the parent screen hierarchically (“Inbox” goes up to “Mailboxes”). Alternatively, a non-related destination can be linked here. The page title is virtually always present, and starts large, but shrinks with the header as the user scrolls. The optional right page action(s) can be displayed as a single text action or multiple icon actions.

On Android, the page title is left-aligned. There doesn’t need to be anything to the left of the page title, but (a) if the page is a top-level page and there’s a hamburger button in the app, it appears there, or (b) if this page follows another sequentially, you can optionally add a back button.

Primary Navigation Destinations

iOS vs Android primary nav differences

The main parts or “destinations” in the app are laid out in different ways.

On iOS apps, primary destinations in the app are listed as tabs across the bottom.

  1. There are 2-5 tabs total
  2. They are labelled in size 10 font
  3. They represent the main destinations or “nouns” of the application

For what it’s worth, many popular third-party iOS apps also conform to a few additional guidelines:

  1. Any tab that represents the primary action of the app – for instance, adding a new photo in a photo-based app – is centered
  2. Any profile- or settings-related tab appears last
  3. Search appears second

iOS default apps, on the other hand, (1) discourage actions being in the tab bar, (2) don’t have profile- or settings-related tabs, and (3) make search appear last.

The biggest difference on Android apps is that the same primary destinations are more spread out throughout the interface – often between (a) a hamburger button, (b) a search bar, (c) tabs, or (d) a floating action button. We’ll talk about all 4 in later sections. Oh, and note: Android does use bottom navigation more recently, similar to iOS – so you may not have that big of a difference at all.

Secondary Navigation Destinations

iOS vs Android secondary nav UI differences

On iOS, navigation destinations that can’t fit in the bottom tab bar can (a) be shunted into a catch-all “More” tab or (b) appear as actions in the top-left or top-right of other destinations.

On Android, secondary nav destinations are listed in a side menu accessible by pressing a hamburger button.

Note: while Apple doesn’t specifically encourage use of the hamburger button (or use it in their default apps), a lot of third-party iOS apps do have one, and it’s simply one more choice to make if you want to use it or not. A best practice is to avoid anything that hides important stuff, because obvious always wins.

“Back” Pattern on iOS vs. Android

iOS vs Android back navigation differences

On iOS, you can navigate backwards in 4 different ways, depending on the context.

Method of navigating back (iOS) Context in which it works
Press “Back” action on top-left of screen Any screen on which a “Back" action appears
Swipe right from left edge of screen Any screen on which a “Back” action appears in the upper-left
Press “Done” action on top-right of screen Non-editing modal views
Swipe down on screen content Modal or fullscreen views

What are modal and fullscreen views? Glad you asked.

iOS modal back navigation UI

Modal views are single-screen tasks that appear by sliding up in the foreground, while allowing the previous screen to peek through at the top, receded into the background. You can dismiss them by swiping down or tapping a “Back” action at the top.

Fullscreen views are media like photos or videos that take up the entire screen. They’re dismissed by swiping down on both iOS and Android.

On Android, navigating back is much simpler: for Android 10 and newer, simply swipe from either side of the screen in – this will always navigate back. For Android 9, use the omnipresent “Back” button the bottom-left of the screen.

iOS vs. Android Control Design

Primary call-to-action buttons

iOS vs Android primary action button UI differences

On iOS, the page’s primary button will usually be on the upper-right.

On Android, however, the page’s primary button will often appear in the bottom-right as a floating action button, or FAB for short.

It’s worth noting that each platform will still have exceptions. Let’s take a look.

iOS vs Android secondary action buttons UI differences

Occasionally on iOS, important page actions will appear on a bottom toolbar. Apple likes to stress this is reeeeally different from a tab bar, but come on now.

Likewise, occasionally on Android, important actions will appear at the top of the screen.

Search on iOS vs. Android

On both iOS and Android, search is a common yet highly flexible control. Sometimes it’s the primary point of the app, other times it’s basically an edge use-case, and most of the time, it’s in between the two. As you might expect, each platform allows for some flexibility here. Let’s look at common paradigms.

iOS vs Android search UI differences

One difference between iOS- and Android-style search:

  • To cancel the search, press “Cancel” on iOS or “←” on Android
  • To clear the current query, but remain on the search screen, press “X” on iOS or “X” on Android

When search is a highly important functionality, iOS and Android will display the search bar right away. As always on these platforms, tapping the search bar will bring up a totally separate screen.

When search isn’t as critical or common, you can access it via other places.

iOS vs Android search access UI differences

On iOS, it’s common to see search as one of the tabs in the primary tabs, or an action in the top nav bar.

On Android, you’ll also see it in the contextual actions on the top bar as well.

iOS & Android Action Menus

iOS vs Android bottom actions UI differences

On iOS, action menus can be triggered by any button or attempting to take any action. They slide up from the bottom, where they’re easily within thumb’s reach.

On Android, however, bottom sheets only appear when you tap a three-dot “kebab menu” icon (which is the Android icon for “more options”). And appearing from the bottom typically only happens when there’s a lot of possible actions.

Both platforms have standards for on-action menus.

iOS vs Android action menus UI differences

A newer (iOS 13) iOS feature called “context menus” shows related actions when you tap and hold an element. When the context menu is shown, the background is blurred out.

And on Android, many menus will appear in-place directly on the element. In newer versions of Android, the menu will cover the kebab icon itself.

Selection controls

On mobile, it’s smart to handle choices among few options differently from choices among many options.

iOS vs Android picker menu UI differences

For choices among relatively few options, use a picker control on iOS. Pickers can appear anchored at the bottom (shown above), or inline with the content (see “Date Pickers” below for an example).

For choices among few options on Android, it’s typical to use a dropdown menu (which appears in-place) or a modal dialog (which appears centered and darkens the app background) listing the options.

iOS vs Android picker screen UI differences

For longer lists of options, or when multi-selection is possible, it’s common to see a dedicated “picker screen” on both iOS and Android. One of the biggest beginning designer mistakes in mobile design is not dedicating a full screen to the picking of a single choice with many options.

Date pickers on iOS vs. Android

iOS vs Android date control UI differences

On iOS, date pickers take the appearance of any other picker control, but with a column for day, month, and optionally year.

Android has its own custom date picker control. You can choose to include year, not include it, or allow the user to choose whether or not they want to include it.

Resources: iOS picker; Android date picker (notice the differences in the Material Design spec)

iOS and Android Tabs

iOS vs Android tabs UI differences

It’s worth noting that iOS doesn’t have a control that visually resembles “tabs”. Instead, Apple calls for you to use a segmented button to navigate between sister views.

On Android, a “flat design” style tab is used for the same display.

“Undo” Pattern on iOS and Android

iOS vs Android undo control UI differences

On iOS, alerts appear in the center of the screen, but you’ll also see alerts slide up from the bottom of the screen (technically called “action panels” in iOS lingo). Destructive actions (like deleting something) are red.

On Android, some alerts appear in the center of the screen. However, for alerts that don’t require user input and should disappear after a few seconds, you can use “snackbars”. Snackbars are fantastic, because (a) they give you a way to tell the user that their action was a success, and (b) you can add an action or two on them – which makes them the ideal place for “Undo”. And when it comes down to it, I’d rather give my users the option to undo a mistake then ask them twice every single time they try to make an important decision.

iOS vs. Android Typography

Default Font

iOS vs Android default fonts SF and Roboto differences

While it’s not necessary to set an iPhone app in the default iPhone font, or likewise for Android, it’s good to know what the system fonts are, just in case you want to imitate the style of a native app.

The iOS system font is called SF. It’s a compact font designed for legibility at small sizes. You can download SF here.

The Android system font is called Roboto. While it’s a very similar font to SF overall, it has taller letterforms and a bit more breathing room. You can download Roboto here.

Also, a lot of the Android OS is set in a proprietary Google font called Product Sans, which is not available for third-party use.

Text styles

iOS vs. Android Other Platform Standards

App Icon Size & Shape

iOS vs Android app icon design differences

You should design the following sizes of icons for iPhone apps:

Icon Size Where it’s used
180x180 px iPhone Home screen for @3x phones (e.g. all iPhone 12 models, 11 Pro, X, Xs, 8+)
120x120 px iPhone Home screen for @2x phones (e.g. 11, XR, 8)
1024x1024 px App Store

Ultimately, your icon may be used at other sizes as well, but if design it at 60px, then verify it looks good at 120x120, 180x180 and 1024x1024px, you’re golden.

Design the following sizes of icons for Android apps:

Icon Size Where it’s used Multiple of 48x48 px
48x48 px Home screen (medium DPI phones) 1x
72x72 px Home screen (high DPI phones) 1.5x
96x96 px Home screen (xhdpi phones) 2x
144x144 px Home screen (xxhdpi phones) 3x
192x192 px Home screen (xxxhdpi phones) 4x
512x512 px Large version for Google Play store (all devices) N/A

So if you (1) design a beautiful vector icon at 48x48px, (2) zoom in to 400% to make sure it still looks great, and (3) create a separate version at 512x512 px, you’re golden.

When you first look at the tables of icons you need for either iPhone or Android, it can seem pretty daunting. But as long as you know the base size, and can check and export at various larger multiples, it’s really not that hard at all.

iOS vs. Android Tap Target Minimum Size

Platform Minimum tap target size
iOS 44x44pt
Android 48x48dp

Note that Apple’s points (“pt”) and Android’s device-independent pixels (“dp”) are functionally equivalent. They simply refer to a baseline size (the same as the CSS unit “pixels”) that measures independent of whether the screen is normal definition, high definition, ultra-high definition, or whatever else screen people are making these days!

Between Android’s larger tap target size and smaller numbers of pixels-per-screen, Android apps tend to have a slightly more clean, airy appearance than their iOS brethren.

Design Language in Material Design vs. iOS

In trying to show off differences between the two design languages and philosophies, this guide breezes over large parts of the the iOS and Material Design language that are similar. For more on those, you’ll want to dive into the official documentation of each design system.
