What is App Load Time?

The term app load time is an essential measure of UX, i.e., User Experience can be defined as a certain amount of period which is taken for the user-mode apps to completely initialize before their UI, i.e., User Interface starts to provide access to the user or becomes clickable for the end-user.

The mobile or web applications that take more time to load or have slower app load time might point in the direction of issues like:

  • User Frustration
  • Resource Bottlenecks
  • Other System Issues

As the app load time is a key metric, that's why nowadays businesses from various industries are paying specific importance to this factor. Some of those industries are Retail, Entertainment, Education, and Travel, etc.

It can be said that the app load time is highly correlated with the rates of conversions, adoption, and also engagement in the mobile as well as web applications.

According to a recent survey, slower app load time was the major source of customer frustration with the vote of more than 50% of the total users, and approximately 20% of the users decided to not engage with a brand with prolonged app load times.

The whole process of the web or even mobile app development can be a little overwhelming sometimes and seems to keep moving further away from the user. An app is not just an app, but an entire world resides in it consisting of frameworks, libraries, modules, loading packaging, and much more.

We know that in today's era of technology to have a faster app load time has become a necessity for applications so that they can make their targeted audience stay on their apps as long as possible. Now, let's dig in and know how to have a faster app load time:

Content Delivery Network

The Content Delivery Network, also known as the CDN can help you in scattering your site across various servers that are available in different geographical locations. With CDN, the user can also offload the bandwidth, which can further lower down the risk in down disruptions that are caused due to large user traffic volumes.

Here are a few popular Content Delivery Networks:

  1. Edgecast
  2. CloudFlare
  3. AWS CloudFront
  4. Incapsula
  5. Fastly

Content Delivery Network can help you in adding more value by transferring the static files like JS, CSS, images, etc. via web servers that are close to the end user's actual physical location. So, the shorter amount of proximity results in faster load time.

Light Code

It is always beneficial to have a lighter code, so try to minimize your code as much as possible. What it means is to make your codebase of CSS, JavaScript, and HTML compact by transforming it into a limited number of files so they can be easily optimized during the runtime. Bulky codebases is a popular cause of slow app loading times.

For example, suppose your app has seven JS files and then seven separate HTTP requests to fetch those seven javascript files. So, why not concatenate the seven JS files into one streamlining file, as this will minify the code and make it light as well.

Start Time Loading

The user’s first interaction with the app is crucial, and now, users are impatient than ever, they wish the app to get open even before clicking on the icon. If the app takes too much time to open, it will frustrate the users, and this will push your app towards the risk of getting uninstalled.

The starting time of the app is when it loads all the data to show users, and loading a hell lot of content will slow the process. So, all you need to do is load less at the time of Startup loading.

However, on the practical side, it is not that easy to resolve these issues as with every new version the resource files tend to increase, and the process requires more time to load. You need to write the boilerplate codes especially using the dependency Injections.

app loading example

The other tip you can use is to work smart on the background initialization processes of the app. Most of the apps inform the server whenever a user opens the app and collect the relevant data that the user may need later.

All these processes take place in the background but start with the app’s starting time, which delays the starting time further. What you can do is, delay the background processes a bit so the load time will be less, and the user will see the screen faster.

However, these processes will help you in a very small way, and there is nothing you can do to decrease the significant amount of load time. The app always requires to fetch the data from the server to show the user everything.

Although you can use a creative loading page like the company’s logo or anything instead of a white screen to keep the user calm for seconds.

Optimize the Images

You can also improve app loading speed by optimizing images that are used in your mobile or web application. With Image Optimization, the user can easily ensure the adopting of appropriate image sizing as well as correct image formattings like PNG, GIF, and JPEG. The image optimization process is also one of the simplest ways to improve app loading speed.

optimize the image

The main objective in image optimization is to reduce the size of the image file as much as possible but without compromising with the quality of the image as well.

Below are a few popular Image Optimization tools:

  1. Online Image Optimizer
  2. SuperGIF
  3. JPEG & PNG Stripper
  4. Smush.it

Switch off Plugins

In some cases, we involve way too many plugins in the application that it results in slowing down the app load time. That's why it is suggested by many domain experts, to switch off those plugins that are not being used by the application.

It is a great way to quickly improve your app load time by just deactivating the plugins that are unnecessary and are not required in your app's functioning. Another trick that might provide you some assistance is 'File Compression', where a tool named 'Gzip' can come very handy in turning your app into a zip file.

Wrap Up

So, these were some of the most effective as well as efficient ways to help you to Reduce App Loading Time for your web and mobile application. But always remember to measure app load time as well regularly.
