The Average Cost for Building a Mobile App
If you want to build a smartphone app for two platforms (Android and iOS), you'll need to budget closer to $100,000 rather than $10,000. The best way to speak about the cost of mobile app growth, in our opinion, is to think about it in terms of complexity.
For a single platform (25,000 - 50,000)$ - SIMPLE
Around 325–650 hours of work will be logged by the development team (developers, Scrum Master).
The suggested QA basic plan for this type of app includes 50 hours of QA specialist work per month.
If you have two developers per platform, production will take 4 to 9 weeks.
What do we mean by "Simple app."
Getting a good picture of a collection of essential features with basic business logic,
Consisting of up to five screens with a primary user interface and no custom elements
This type of app is typically developed by start-ups searching for a business fit.
For a single platform (50,000 - 100,000)$ - With Some Complexities
Around 650-1100 hours will be worked by the production team (developers and Scrum Master).
The QA Extended plan is recommended for this type of app since it includes 80 hours of QA specialist work per month.
If you have two developers per platform, production will take about 10-15 weeks (2-4 months).
What do we mean by "With some Complexity."
Consisting of around 6-15 screens and a few complex features of intermediate business logic
With a few exclusive UI elements and animations
For up to two languages of localization
For a single platform (100,000+)$ - Complex App
More than 1100 hours of work will be logged by the production team (developers and Scrum Master).
The suggested QA Enterprise plan for these apps includes 150 hours of QA specialist work each month.
If you have two developers per platform, production will take at least 16 weeks (or more than 3 months).
What do we mean by "Complex app."
There are over 15 screens in total, with many dynamic features and sophisticated business logic.
With a completely customized user interface and advanced animations, and a sizable user base (multilingual)
That necessitated creating a complex architecture, multiple integrations, or the need to meet high-security requirements.
Factors that trigger the cost of Mobile App Development
Features and its complexity:
Maintenance Cost: This is an essential aspect that many would-be app developers overlook. We tend to believe that software development costs are only incurred once the solution is complete. This isn't correct. Customer and their preferences are continually shifting. The product must adjust to these shifts (not adapting to market changes is one of the most common mistakes in mobile app development). That's why app maintenance and upgrading are critical aspects of the development process – and a cost factor.
