Buyer’s Guide

What Are the Different Types of Mobile Apps?

1. Native Apps: Native apps are designed for a particular mobile app development platform. These apps cannot run on different Operating Systems. They are developed using specific mobile app development tools and languages supported by the respective app development platform. For instance, an app developed using Xcode and Objective-C can only run on iOS. Native mobile apps are very fast and offer high performance and exceptional user experience. However, dedicated apps can be expensive to develop.

2. Mobile Web Apps: Mobile web apps display web pages on the web browsers of the mobile. They run on web-hosted servers and are not installed in the mobile device. These apps are commonly written in CSS, HTML, Javascript, JQuery, and such web technologies. They are popular amongst businesses since mobile web apps provide easier access to the websites at a reduced cost, allowing more clients to connect with the brand. 

3. Hybrid Apps: As the name suggests, hybrid apps are a combination of native and mobile web apps. Hybrid apps employ multi-platform mobile app development frameworks and tools such as HTML5, CSS, Adobe PhoneGap, Corona SDK, JQuery Mobile, etc. These apps can be downloaded from app stores as well as run on mobile browsers. They are easy to build and offer a single app for all platforms, however, are slower than native apps.

What Are the Most Popular Mobile App Development Platforms?

1. iOS: iOS is Apple's unique operating system that runs on Apple devices, in particular, iPhone, iPad, and iPod Touch. An iOS app developer can either design a native app using app development languages like Swift and Objective-C or use React Native or Xamarin (C# & F#) languages for cross-platform mobile app development.

Apple also offers an iOS software development kit (SDK), which consists of numerous tools, frameworks, languages, etc. to simplify the iOS app development. One such framework is the Cocoa Touch, which includes UIKit, PushKit, GameKit, MapKit, Foundation Kit, and MusicKit.

2. Android: Android is an open-source platform that empowers android app developers to freely create and distribute apps while eliminating any intricate review processes. For Android app development, developers can incorporate their own functionalities and still enables users to avail new features that are launched by Google routinely. The latest update of Android is Android 10.0.

Android Software Developer Kit offers libraries of Java code to the android app developers, which when included in the project simplifies the access to the device functionality. The Android SDK also includes Debugger, sample source codes, tutorials for the Android OS, as well as relevant documentation for the Android APIs.

3. Hybrid: Hybrid mobile app development is gaining popularity as apps developed on this platform can easily run on multiple operating systems, thus saving the client substantial time and money on the app development front. Cross-platform mobile app development compiles various versions of the same application for separate operating systems.

Mobile app development tools such as PhoneGap, Xamarin, Flutter, React Native, etc. allows cross-platform mobile app developers to create a hybrid mobile app. While developing hybrid apps, it is advisable to opt for a robust analytics tool to identify and fix any bugs or glitches in real-time. 

Apart from the above-mentioned platforms, mobile applications can be developed across several other app development platforms such as Windows, Blackberry, wearable programs.

Why Do Businesses Require Mobile App?

1. Expand Customer Base: In the era of the smartphone, companies that do not offer responsive design or mobile apps can suffer a great loss as it misses out on a vast number of users. In addition, mobile applications allow clientele from different geographical locations access to the product or brand. 

2. Enhanced Customer Engagement: Mobile applications allow users to obtain any type of information in a fraction of time, thereby boosting customer engagement and retaining clients. Furthermore, it is easier for brands to introduce innovative, advanced, and user-friendly features into the mobile app to attract more consumers towards the product. 

3. Understand User Behaviour: Mobile apps can be extremely useful in analyzing the preferences and activities of users. Companies can monitor the most-visited section of the app and offer customized promotional offers to further enhance the business goal. Brands can send push notifications via the app to easily reach the target audience.

4. Maximize Revenue: Mobile applications serve as a huge opportunity for businesses to boost their ROI. Components such as in-app purchases and advertising allow companies to gain additional income on top of the direct revenue generated through the sales of the product via the app.

What Are the Top Benefits of Outsourcing Mobile App Development?

The following are the top reasons why businesses must outsource mobile app development:

1. Cost-Effective: The first and foremost advantage of outsourcing mobile app developers is that it is cost-efficient. Companies save crucial monetary resources by eliminating excessive charges spend on hiring an in-house team as well as setting up relevant infrastructure.

2. Faster Turnaround: The best mobile app development companies understand the essence of time and offer timely delivery of the mobile app. Moreover, expert app developers can quickly act on any requirement changes demanded by the customers and provide faster updates.

3. End to End Support: Professional app developers are apt to handle every app development phase. Whether a company requires assistance in the conceptualization of the application or its deployment in the marketplace and app stores, the best mobile app developers expertly manage these tasks while eliminating various risk factors.

4. Latest Technologies: The leading companies dedicatedly focus on app development and, thus, are up-to-date with the new, cutting-edge technologies. The app developers can effectively integrate these technologies to ensure the creation of the state of the art mobile application.

5. Quality Developers: Outsourcing mobile app development services also give businesses access to a vast pool of talent. The project can be assigned to either local or international app developers depending on the need of the project and the expertise of the service provider.

6. Support and Training: The best mobile app development companies offer post-launch support and training services to their client companies. They provide training to the in-house staff regarding the detailed working of the application. Moreover, if the app experiences any glitches, the app developers can swiftly resolve the issue.

Mobile app development companies aid in creating a robust, reliable, and error-free app. According to the mobile app download and usage report by GoodFirms,18.55% of customers have uninstalled mobile apps because of technical errors or crashes in the app. Hence, it is imperative that companies planning to launch their own app hire professional mobile app developers.

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 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.
