a great user experience on slow networks and offline.</p> <p>The quality of a network connection can be affected by a number of factors, such as the following:</p> <ul> <li>Poor network provider coverage.</li> <li>Extreme weather conditions.</li> <li>Power outages.</li> <li>Entering permanent "dead zones," such as in buildings with walls that block network connections.</li> <li>Entering temporary "dead zones," such as when traveling on a train and going through a tunnel.</li> <li>Time-boxed internet connections, like those in airports or hotels.</li> <li>Cultural practices that require limited or no internet access at specific times or on specific days.</li> </ul> <p>Your goal as a developer is to provide a good experience that lessens the impact of changes in connectivity.</p> <h2 id="what-to-show" data-text="Decide what to show your users when they have a bad network connection" tabindex="-1">Decide what to show your users when they have a bad network connection</h2> <p>The first question to ask is what success and failure of a network connection look like for your app. A successful connection is your app's normal online experience. Connection failure includes both how your app behaves offline and on laggy networks.</p> <p>To determine how to handle connection failure, ask yourself these important UX questions:</p> <ul> <li>How long do you wait to determine the success or failure of a connection?</li> <li>What can you do while success or failure is being determined?</li> <li>What should you do if the connection fails?</li> <li>How do you tell the user what's going on?</li> </ul> <h3 id="inform-state" data-text="Inform users of their current state and change of state" tabindex="-1">Inform users of their current state and change of state</h3> <p>Tell the user both the application's state and the actions they can still take when they have a network failure. For example, a notification might say the following:</p> <blockquote> <p>You seem to have a bad network connection. Not to worry! Messages will be sent when the network is restored.</p> </blockquote> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/the-emojoy-emoji-messagin-70c51ef118a7.png" alt="The Emojoy emoji messaging app informing the user when a change in state occurs." width="335" height="601"> <figcaption class="wd-caption"> Clearly inform the user when a change in state occurs as soon as possible. </figcaption> </figure> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/the-o-2016-app-informing-f644b43fd92eb.png" alt="The I/O 2016 app informing the user when a change in state occurs." width="335" height="601"> <figcaption class="wd-caption"> The Google I/O app used a "toast" to let the user know when they were offline. </figcaption> </figure> <h3 id="inform-improve" data-text="Inform users when the network connection improves or is restored" tabindex="-1">Inform users when the network connection improves or is restored</h3> <p>How you tell the user their network connection has improved depends on your application. Apps that prioritize current information, such as weather or stock market trackers, should auto-update and tell the user as soon as possible.</p> <p>We recommend that you let the user know your web app has updated "in the background" by using a visual cue like a Material Design toast element. This involves detecting both the presence of a service worker and an update to its managed content. You can see a code example of this <a href="https://github.com/GoogleChrome/sw-precache/blob/master/demo/app/js/service-worker-registration.js#L29">function at work</a> here.</p> <p>One example of this is <a href="https://chromestatus.com">Chrome Platform Status</a>, which posts a note to the user when the app has been updated.</p> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/an-example-weather-app-656cb36f8252f.png" alt="An example weather app." width="324" height="598"> <figcaption class="wd-caption"> Some apps, such as the weather app, need to auto-update because old data isn't useful. </figcaption> </figure> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/chrome-status-uses-toast-0157248fc0b6d.png" alt="Chrome Status uses a toast." width="336" height="598"> <figcaption class="wd-caption"> Apps like Chrome Status use toasts to let the user know when content has been updated. </figcaption> </figure> <p>Some apps can always show the last time they were updated. For example, this is especially useful for currency converter apps.</p> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/the-material-money-app-be-d96547b7d1b9b.png" alt="The Material Money app being out-of-date." width="324" height="598"> <figcaption class="wd-caption"> Material Money caches rates… </figcaption> </figure> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/material-money-has-been-u-1b9996995200f.png" alt="Material money has been updated." width="324" height="598"> <figcaption class="wd-caption"> …and notifies the user when the app has been updated. </figcaption> </figure> <p>News apps can show a simple tap-to-update notification informing the user of new content.

One example would be an ecommerce site that can be browsed offline, but disables pricing and the Buy button until a connection is reestablished.</p> <p>Other forms of contextual states can include data. For example, the financial app Robinhood uses color and graphics to tell the user when the stock market is open. The whole interface turns white and then grays out when the market closes. When the value of a stock increases or decreases, each individual stock widget turns green or red depending on its state.</p> <h3 id="educate-users" data-text="Educate the user so they understand what the offline model is" tabindex="-1">Educate the user so they understand what the offline model is</h3> <p>Most users are used to always having a network connection. You need to educate them about what changes in your app when they don't have a connection. Tell them of where large data is saved and give them settings to change the default behavior. Use multiple UI design components (such as informative language, icons, notifications, color, and imagery) together to convey these ideas, instead of relying on a single design choice, such as an icon on its own, to tell the whole story.</p> <h2 id="provide-offline-experience" data-text="Provide an offline experience by default" tabindex="-1">Provide an offline experience by default</h2> <p>If your app doesn't require much data, then cache that data by default. Users can become increasingly frustrated if they can only access their data with a network connection.</p> <p>Try to make the experience as stable as possible. An unstable connection makes your app feel untrustworthy. An app that lessens the impact of a network failure <a href="/articles/user-centric-performance-metrics#defining_metrics">delights</a> its users.</p> <p>News sites can benefit from auto-downloading and auto-saving the latest news, maybe saving data by downloading only the text, so a user can read today's news without a connection.

Auto-download files only if a user has specifically asked for this behavior through a settings menu. Make sure the pin or download UI is obvious to the user and not hidden by other UI elements.</p> <p>One example of this is be a music player that requires large files. The user is aware of the associated data cost, but may also want to use the player offline. Downloading music for later use requires the user to plan ahead, so you probably want to educate the user about it during onboarding.</p> <h3 id="clarify-availability" data-text="Clarify what is available offline" tabindex="-1">Clarify what is available offline</h3> <p>Be clear about what options you're providing. You might need to show a tab or setting for an "offline library" or <a href="/content-indexing-api">content index</a> so the user can see what they have stored on their device and what needs to be saved. Make sure the settings are concise, and be clear about where the data is stored and who has access to it.</p> <h3 id="show-cost" data-text="Show the actual cost of an action" tabindex="-1">Show the actual cost of an action</h3> <p>Many users equate offline capability with 'downloading'. Users in countries where network connections regularly fail or aren't available often share content with other users, or save content for offline use when they have connectivity.</p> <p>Users on data plans sometimes avoid downloading large files for fear of cost, so you might also want to display an associated cost so users can make an active comparison for a specific file or task. For example, the aforementioned music app could detect whether the user is on a data plan and show the file size so the user can see the cost of a file.</p> <h3 id="prevent-hacks" data-text="Help prevent hacked experiences" tabindex="-1">Help prevent hacked experiences</h3> <p>Users often hack an experience without realizing they're doing it. For example, before cloud-based file-sharing web apps existed, it was common for users to save large files and attach them to emails so they could continue editing those files from a different device. Good UI solves the problem users are trying to solve without getting pulled into the hacked experience. For example, provide a way to share large files across devices, instead of making attaching large files to emails more user-friendly.</p> <h2 id="transferable" data-text="Make experiences transferable from one device to another" tabindex="-1">Make experiences transferable from one device to another</h2> <p>When building for flaky networks, try to sync as soon as the connection improves so that the experience is transferable. For example, imagine a travel app losing a network connection midway through a booking. When the connection is reestablished, the app syncs with the user's account, letting them continue their booking on their desktop device and making the experience feel seamless.</p> <p>Tell the user what state their data is in. For example, you can show whether the app has synced. Educate them where possible, but try not to overwhelm them with too much messaging.</p> <h2 id="inclusivity" data-text="Create inclusive design experiences" tabindex="-1">Create inclusive design experiences</h2> <p>When designing your UX, seek to be inclusive by providing meaningful design devices, simple language, standard iconography, and meaningful imagery that guide the user to complete the action or task without getting in the way.</p> <h3 id="clear-language" data-text="Use simple, clear language" tabindex="-1">Use simple, clear language</h3> <p>Good UX isn't just about designing your interface. It includes the path a user takes through your app, and everything they encounter along the way, including the language the app uses to describe that journey. When explaining UI components or the state of the app, avoid tech jargon. The word "offline" often isn't clear enough to tell the user what your app is doing.</p> <div class="wd-switcher"> <div class="wd-compare"> <div class="compare-worse">Don't</div> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef.png" alt="A service worker icon is a bad example." width="350" height="149" srcset="https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_36.png 36w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_48.png 48w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_72.png 72w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_96.png 96w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_480.png 480w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_720.png 720w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_856.png 856w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_960.png 960w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_1440.png 1440w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_1920.png 1920w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-service-worker-icon-is-9ab93716e75ef_2880.png 2880w" sizes="(max-width: 840px) 100vw, 856px"> <figcaption class="wd-caption"> Avoid terms non-technical users probably won't know. </figcaption> </figure> </div> <div class="wd-compare"> <div class="compare-better">Do</div> <figure style="display: inline-block; max-width: 45%;"> <img src="/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257.png" alt="A download icon is a good example." width="350" height="149" srcset="https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_36.png 36w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_48.png 48w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_72.png 72w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_96.png 96w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_480.png 480w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_720.png 720w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_856.png 856w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_960.png 960w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_1440.png 1440w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_1920.png 1920w,https://web.dev/static/articles/offline-ux-design-guidelines/image/a-download-icon-is-good-53eec1dd7a257_2880.png 2880w" sizes="(max-width: 840px) 100vw, 856px"> <figcaption class="wd-caption"> Use language and imagery that describe what the user is actually doing. </figcaption> </figure> </div> </div> <h3 id="multiple-design-devices" data-text="Use multiple design devices to create accessible user experiences" tabindex="-1">Use multiple design devices to create accessible user experiences</h3> <p>Use language, color, and visual components to show a status or change of state.
