Buyer’s Guide

What Are the Factors Affecting the Mobile App Development Cost?

The cumulative cost of developing a mobile application depends on numerous factors.

1. Platform: The primary emphasis of any app development falls on the concept and idea of the app. However, the type of platform selected to develop the app is equivalently essential. Businesses must opt for a mobile app development platform that resonates with their previous apps as well as future proposals.

The mobile app development platform can determine the base cost of the app. For instance, the app development cost for the iOS platform is relatively costlier than the Android or Hybrid platform. 

2. App Size: The size of the app plays a significant role in finalizing the mobile app development cost. The number of screens required in the app along with its backend functionalities such as databases, user management portals, storage, etc. is reviewed to assess the app development cost.

Extensive storage, multiple screens, and complex backend features can raise the overall price of the app. However, if data storage is required in the future, it is advisable to build data compression during the development phase to avoid unnecessary upgrades and charges in the long term. 

3. Plugins and Integrations: In this era, most apps offer third-party data integrations and plugins to enhance the user experience. The most common plugins incorporated in the apps are social media extensions. For these integrations to work flawlessly, app developers need to formulate an advanced Application Programming Interface (API).

API consists of a set of routines, tools, and protocols that allows the interaction of the application with other devices. Installing APIs will supplement the app development cost.

4. Security: Data security is crucial in the digital age. Nevertheless, the level of encryption required by each app varies based on its type and functionality. If an app gathers the personal data of the user or facilitates payment gateways, a very high level of app encryption is essential.

It is advisable to discuss the type of data security required for the app in the initial stages as the later addition of data encryption could cost significantly more.

How Much Time and Money Does It Take to Build a Mobile Application?

The time and money invested in developing a mobile app chiefly depend on its complexity. A recent survey by GoodFirms on the mobile app development cost and time survey highlights the following findings:

Cost: 

  • Simple App: An app having basic features such as social media login, email subscription, etc. cost from $24800 to $59200.
  • Moderate App: An app with customized UI features, payment gateway, API integration, can roughly cost between $36100 to $85200.
  • Complex App: An app with cutting-edge functionalities such as third-party integration support, complex back-end, customized animations, etc. can be developed by paying approximately $59500 to $137200. 

Time: 

  • Simple App: Developing an app consisting of basic features can take about 4 to 11 weeks.
  • Medium Complexity App: The app developers can deliver these applications that include more complicated features within 7 to 16 weeks.
  • High Complexity App: Creating a customized app with the most advanced features can take around 11 to 26 weeks.

How to Shortlist Mobile App Development Companies?

It is critical to thoroughly research each and every company to find the best one out. Below are a few points you must consider when hiring mobile app developers for your dream app development project whether it is for iOS, Android or any other platform:

1. Portfolio: A companies portfolio provides you insight within the working pattern and the type of projects the top app developers have curated. It also highlights their strengths and weaknesses allowing you to consider their candidature. A portfolio also emphasizes on their proven records in various industries, allowing you to assess and hire mobile app developers having experience relevant to your project.

2. Client Reviews: Nowadays it is indispensable for all businesses to gather client feedback and publish reviews. Reading testimonials and online recommendations about the app developers’ work as social proof. Authentic positive reviews will provide you with great confidence in making the decision of selecting the right mobile app development company for your android app development or ios app development project.

3. Team: Researching the mobile development team working for the mobile app design & development company is beneficial as they are going to work on your smartphone app project. Check the Linkedin profile of executives, project managers, tech leads, etc. and hire mobile app developers after evaluating their talent, experience, and past mobile application development projects.

4. Cost: Customarily, the cost of an entire mobile app development project is based on the features integrated into the app, its scope for scalability, and its complexity. Another determining factor is the time taken to develop the application. Experienced app developers may offer rapid deployment of an app at a higher cost whereas, inexperienced app development agencies may require multiple revisions thereby costing you nearly the same while taking longer time-span.

5. Meeting with CEO: It is important to understand the vision and values of an organization and the best person you must contact for this is the CEO of the mobile app design & development company. Visions, values, and culture of the company matter a lot, especially if you are going to partner with them for long term mobile application development projects.

Questions to Ask Before Hiring Mobile App Developers

Out of the numerous mobile app agencies, several seem eligible contenders to work on your dream project. However, only a handful may fit suit to a fraction! The question is how to identify whether a company is getting its money’s worth?
