More than 48% people in the world own a smartphone and the number of people having smartphones is increasing yearly, according to this survey.

Most of the businesses with high conversion rates get conversion from mobile apps. To get the most out of your mobile application it must be optimized on every level.

But how can you measure a mobile application’s performance?

Through these mobile app development performance metrics :

  • UX and performance metrics
  • Engagement KPI metrics
  • Revenue metrics

All of the aforementioned categories are important to optimize and measure and improve mobile app performance.

What Is Performance Metric?

KPIs, Key Performance Indicators, are also known as performance metrics. The performance of any mobile application is measured and depends on KPIs.

Just like web analytics, performance metric is analytics for mobile applications. They help see how well a mobile app is doing, what can be improved, ideas on where to improve, and how improvement can be done. It also helps at the development stage to build an app that caters all the concerned areas customers are looking for.

Why Measure App’s Performance?

If you don’t know where and when your app needs improvement and engagement how will you take necessary steps? If you will not take the steps needed then application’s performance will continue to deteriorate and your business will continue to lose customers. The mobile app will not be able to attract and retain users, losing potential customers.

To make right decisions, to improve business, to retain users and convert them into clients you have to know insights. Performance metrics also help you optimize app’s performance from a business standpoint by helping you understand the target audience.

  • Acquisition
  • Engagement
  • Conversion
  • Performance
  • Outcomes

Whether it is android development or iOS development, above mentioned aspects necessary to keep track of for making better business decisions.

How To Measure Mobile App Performance

To measure the performance you need to have a clear vision of the end goal and results you want to achieve. Following is the list of essential performance KPIs to measure mobile app performance. 

Front-end & Back-end KPIs

Following list of KPIs will give you technical insights of your iOS and Android mobile application. With help of these you can improve the application’s technical aspects like user experience, design, back-end and front-end connection and more. 

Loading speed

Slow loading time is not acceptable anymore. Higher load time means higher bounce rate. The shift from physical to digital world has made everything so fast and people have become less patient. Users expect lightning fast load time whether it is a mobile app or website.

When you avail mobile app development services make sure to check on how fast your app loads on the client side.

If you are looking for mobile application developers then this is the right place. We offer highly experienced android and iOS developers remotely. We take away your hassle of managing development teams so you can focus on business.

Screen size & resolution

Better looking and compatible mobile apps can be developed if screen resolution of the devices is known beforehand. This is hard to determine for android development because there are so many different screen resolutions and sizes available. But for iOS development this is easy because the screen resolution and size of every Apple phone and tablet is defined. 

In Android development a range of screen resolution is defined that caters devices within that range. Still it is better if you know the resolution of devices that the majority of targeted users have.

Crash reports

Sooner or later apps crash but how fast the bug is fixed decides whether it is a good app or a bad one. Operating systems, mobile devices, and the app usage differs so much that it is not possible to cover every possible situation and test case.

Crash reports are important to figure out where, why, and when the crash happened. When you know the why and where, solving the bug would be much easier and quicker. 

Following are apparent reasons of mobile app crashes:

  • Un-intended user behavior
  • Operating system or OS version in-compatibility
  • Undiscovered bug in the code.

OS & Devices

Keeping track of what device and operating system your users have is an efficient way of optimizing your mobile app accordingly. For instance you can go for android development if your target is android phone users or you can specifically target Apple users with iOS development. 

But that is mostly not the case. So you can opt custom app development so you can target bigger audience, i.e. Android and iOS.

Knowledge of operating systems will help fix bugs easily. For example, you hired a developer for mobile app development for iOS and Android users. But the app is crashing on iOS devices. This means it is not properly optimized for iOS devices. If the developer understands this problem they will easily figure it out and solve the issue.

User Engagement KPIs

Building a mobile app means you need user engagement. The focus of the developer should be on:

  • how users will engage with the application 
  • how to make the user experience smooth and fast

Achieving these goals requires time and continuous improvement. Ideally your mobile app should:

  • Attract new users
  • Retain users and keep them engaged
  • Convert users into customer (if they are not already)

This can be achieved by:

  • Analyze KPIs
  • Offer what users want
  • Present the information or product straight away

Following are the user engagement KPIs to take note of.

User Engagement

High user engagement is an indicator of quality mobile apps and good user experience. User engagement is the first step and the rest of the metrics come secondary. If users are not staying on your app what will you measure other metrics for?

  • Features users want
  • Information on product users want
  • Easy to understand navigation
  • Visually pleasing UI

Based on above mentioned criteria you can design and develop a mobile application that caters users hence increase user engagement.

Important note:- 

  • High engagement rate is better
  • User retention increases users engagement

App Retention Rate

Number of users actively using the app monthly, quarterly, or yearly is your app retention rate. Often users download the app but don’t use it after the first one or two times. How many times have you downloaded the app and then just forgotten about it? Eventually that app gets deleted from our phones. Such experience affects application’s retention rates. 

Updates can also negatively affect app retention rate if users think the update is not useful or engaging.

Through this simple formula you can calculate the app retention rate:

(Number of users at the end of a time period – Number of users acquired during this period) / Number of users at the start of the time period X 100.


DAU: Daily Active Users and MAU: Monthly Active Users are the most important performance metrics for mobile app development.

If the DAU and MAU number are going up then it means more users are installing your mobile application, which is good. But if the numbers are going down that means users are moving away from your application. So, you should take necessary steps to engage and retain users.

How can you do that? By reviewing engagement, frontend and backend, crash report and other metrics mentioned above.

DAU and MAU can be misleading when it comes to mobile apps like healthcare because the people will only use the app when they have a concern related to healthcare, which is not that often. 

Churn Rate

Number of users that cancel subscriptions or uninstall the app is equal to the churn rate. If your churn rate is increasing you need to aggressively address the issue, especially if it is your main business model.

Finding out the root cause of why your audience is churning is difficult.

What causes churning?

  • Improper customer base
  • Bad product or service
  • Poor or No customer support.
  • Lacking user engagement.
  • No champion product.
  • User’s financial issues.

How to solve churning?

  • Analyze churning causes.
  • Target the right audience.
  • Customer engagement and support.
  • Educate the customer.
  • Know who is at the brink of leaving.
  • Find your most valuable customers
  • Offer special discounts and incentives.

Session Length

Time every user spends on your app is the session length. It helps you identify how appealing and retaining your app is for users. You can identify the weak points of your app and improve it accordingly.

Cab service, food delivery and other apps do not require users to spend too much time on the app. So, if the user ends up ordering from the app then the metric is success otherwise you can find where users lose interest. 

Event Tracking

Event tracking tracks each user’s engagement with the app. Event tracking helps identify how good your app’s quality and performance is from a user standpoint. There are different tools available to track users and what they are doing in the app.

Exit Rate

Percentage of users that leave or drop off from a screen is Exit rate. You can figure out where users leave and find out why they are leaving or losing interest in the app.

  Total number of visits to a screen
Exit rate = ——————————————————————
Total number of exits from that particular screen

Final Thoughts

Once the application is launched you need to actively measure and analyze KPIs if you want to give top-notch user experience.

Here we talked about the performance of the application from a technical standpoint i.e. technical performance metrics and user engagement KPI metrics. We have not talked about the revenue because it would exceed the scope of this article.
