How to Plan for Your Big Mobile App Launch

How to manage the influx of users after an app launch

Have you ever thought how many users may hit your mobile app once it goes public? As soon as the mobile app launch to the App Store or Play Store, it is available for the public to download and start using. But is your app capable of managing a sudden influx of installations and traffic? Any mobile app needs to be developed in a way so that it can manage high traffic for your big mobile app launch.

At Rubico, we recently developed an app that received 8,000+ users within one week from the launch. The app got 21,000+ users within the first 50 days. Here are some secrets on how we developed the app to manage such a large amount of traffic and still maintain quality performance.

There are many components to take into consideration during the mobile app development process. Most mobile apps allow users to connect with each other and also let the administrator manage transactions and activities on the admin panel.

A mobile app usually contains the following factors:

  • Mobile App Development
    • The mobile app can be developed using Native or Hybrid technology. Each technology has pros and cons.
  • Web Admin Panel Development
    • The Web admin panel allows the admin users or managers to see activities of users who are using the mobile app.
    • The admin panel is mainly developed using a web technology (PHP, Laravel, etc.) and shows all the activities recorded from the app.
  • Web Services
    • Web services are called middle layers and used to communicate the data flow between the mobile app and the web admin along with a database.
    • All dynamic content is updated or fetched from the database using web services.

When we talk about managing a huge user base, all the factors mentioned above need to be developed in a way so that performance does not fall when hundreds or thousands of users hit the app. The following points need to be reviewed and managed while developing a mobile app to manage heavy traffic:

Backend Server (Hosting server)

ITH Backend Server

Improving the performance of the app depends on the performance of the server that hosts your database and Web Services (APIs). The server needs to be capable of managing the traffic easily. It needs to contain the hardware and the applications that are installed on the server.

The hardware needs to be configured well and should have free memory to run the processes. It’s always good to define the size of RAM and the type of server with your server specialists. It will help boost the performance.

At the same time, the server needs to be configured with service for caching the data. This helps further with the load on the server for the increased traffic after your mobile app launch.

Database Transactions

ITH Database Transactions

Database transactions are the most important aspect to consider while developing a mobile application. A mobile app usually communicates with the database via the web services. Web services connect with the database to send and receive data.

If the database is structured well, it will retrieve data quickly, which will help the mobile app perform better. A well-structured database helps with:

  • Saving disk space by removal of redundant data
  • Providing data access faster
  • Keeping data accuracy and integrity

The other important part is how we manage transactions with the database. Do we write queries that are slow to retrieve data? Do we create multiple joins while retrieving data from the database? Your query writing skills can completely change the performance of your app.

It’s important to write queries that help:

  • Specify the field name from which to get data (Don’t use select * from a table when you need access to only a few columns)
  • Use short queries instead of multiple joins (Multiple joins within the queries can take a long time to fetch data)
  • Search on the indexed columns

Long processes in Background tasks

ITH Long Processes

From a user engagement point of view, it’s always good to put long running tasks in the background thread, so that the UI thread doesn’t get blocked. It will help app users continue working on their app activities without waiting for data to be processed on the front end.

Make fewer calls to APIs

ITH Makes less calls

Making a lot of API calls takes up a lot of the process in the background. If there are fewer calls to the APIs it will help run the mobile app effectively. APIs communicate with the database using the queries as mentioned above. So each call to an API will need to get a data result set. Depending on the size of data, and the time taken by the queries, this might slow the app response. So until there is a need, do not make calls to APIs.

Optimized code

ITH Optimizes code

Code quality also plays a key role in app performance. There are several points one should keep in mind while writing code.

  1. Avoid Creating Unnecessary Objects: Unnecessary objects cause the garbage collector to be called unnecessarily, which in turn eats resources needed to boost the performance of the application.
  2. Avoid Background Services: Background services should be avoided to keep running unless absolutely required, as they keep occupying the resources throughout their execution.
  3. Use Standard Libraries: Instead of implementing the same functionality in your own code, use the already-available resource.
  4. Use Optimized Data Containers
  5. Use Cache: Objects which are expensive to create should be implemented in cache. For example, if you have to display some images from the Internet, then you should hold them in memory to avoid downloading them several times.
