Building a mobile app is like building a house. If your budget makes you smile in contentment, your fantasy is the only limit. You may have a huge Victorian mansion with a large living room, an elegant balcony with a view and three bathrooms on each floor. Alternatively, if you’re short on funds, your house will contain only the basic rooms and non-designer furniture. The same rule applies to the creation of mobile apps. Multiple options define the eventual price: the app’s complexity, custom features, ecosystems the app will need to run on, etc.
App development process is difficult to adapt to any specific framework. Especially
if you do not have a detailed idea of what the final product should be.
The maximum that a mobile developer can do is name the price range. Moreover, the resulting estimate does not always correspond to reality. A more accurate cost can be announced after agreeing on clear requirements with a detailed technical specification.
First of all, you must decide on the platform and on which devices your application should work and be used. In some cases, the price can vary depending on this criteria. You can create an application that will only work on iOS or Android. This will save money on the development phase, but will “cut off” users of one of the platforms. An application for both platforms will cost more, but will give full coverage to a mobile audience.
Mobile apps functionality and complexity may vary a lot. There are some that
are being implemented quickly and cheaply. There are some that are expensive, but are being implemented
quickly or that take a long time to implement and are therefore expensive. There are no general
recommendations which features to add to the application or not. This question can be answered
only after a detailed study of a specific idea, research, comparison with competitors.
It happens that without some functions the application is uncompetitive and it just makes no sense to run it. Or, conversely, you can make a wider functionality than others, and become unique.
For instance, let’s take data processing. The more complex the application is, the more data it processes. There is not much data in the calculator, more in the fitness application, and a huge amount in the application for the social network. The developer team needs to think through custom scenarios, choose those that will lead the user to the result faster, and then draw the application screens.
The phone components and external devices that the applications interact with also have something to share with the application and the server. Proximity switch, a light sensor, Bluetooth sensor, and printers with Beacons produce their data. They also need to be processed so that the devices work correctly.
If the application expects data from the server for a very long time, then you can forget about the positive feedback from users. Therefore, do not belittle the value of the backend development team on your project.
Often, the discovery phase helps to understand the exact list of technical requirements and make a detailed technical task. According to a study by the analytic company Clutch, more than 70% of app development agencies surveyed require a discovery stage before moving forward with a project. This step can significantly reduce development time and save time. And according to Clutch.co for a little over half of the firms surveyed, the discovery stage costs less than $5,000.
Android and iOS users should also follow their own habits, which the mobile application must meet. No need to make the design of the Android application as on the iPhone, because it’s more beautiful there. Unusual interface guarantees low user ratings and lower positions in the search. The amount of work depends on the number of application screens. The screen is all that the user will see: starting from the greeting and ending with the subsection "About the application", which reads one out of 20,000. The number of screens depends on the capabilities of the application: trimming functionality, we automatically reduce the amount of work of the designer. Small applications have 5–7 screens, medium-sized applications grow to 10–15, and large applications have more than 20 screens. Optimize design costs allows a prototype, which displays a general view of a mobile application with the proposed functional elements and an indication of user scenarios.
