Today, the digital landscape is flooded with abundance of technologies. Earlier, we had web only, but now we have mobile-first approach. In the age of mobile, the firms with mobile apps are front-runners. However, they have to go through a tough selection between variant available for their mobile application. The mobile app development knocks with diverse paths, which include native and there is hybrid to choose.


It is true that all these development platforms hold deep value at their own place. But, this increases your difficulty to choose one. At first instance, it seems like a puzzle, with which to go for according to your project requirement. You must ponder over all the factors like your business objectives, overall goals, features, user base, etc. A right decision can make or a wrong one can break the success aspect of your business mobile app strategy. Being a business owner, you should consider diverse factors, and examine these options according to their benefits and disadvantages.

It is your responsibility as a business owner to accomplish the expectations of mobile phone users, as they will turn into the loyal customers in the future. We understand that it is a rough task to pick the perfect mobile app development platform. Therefore, we have differentiated Native and Hybrid by explaining their definitions, features, and benefits, here are they-

Define Native App-
A native app, as the name suggests, is the one, which we build, especially for the single platform. For Android app, we use the languages named Kotlin or Java and we use Objective-C or Swift for iOS application.


These applications are built in the languages that are specifically used for a particular platform. Therefore, the users can use them only on that specific platform. For instance, if we develop an app on Android platform, it will serve only the Android users. It will not meet the specifications of iPhone users. In case, you want to serve the users of both platform, then you should get your business mobile app developed for two different versions (Android and iOS).

Now, you have native app for both platform, so these app can access complete functionality of the device. This amplifies the speed and performance. Make sure your native business app is built without bugs, so that it can work without causing error.

Pros Of Native Application Development

Being assigned to a single platform, native application brings a number of advantages, get to know them in detail-

Glitch-free Performance

To carry out native mobile application development, one has to code it for diverse platforms. It requires using specific programming language according to the particular operating system. This way, we own varied versions of a single app (for each specific platform). And, specific app for specific OS runs fast and smooth.

Awesome UX

It is crucial for any mobile application to appeal the users. Otherwise, they will delete it straight after installation. In a native app, the UX is stronger with gesture recognition, smooth scrolling, ample animations and effects, and more elements.

Personal Touch

There is a long list of Android devices in the market with diverse screen sizes. In such scenario, native platform is the only savior to adjust their layout accordingly.

Fast

Native app is optimized separately for Android and iOS for usage of battery and memory. So, it keeps a upper hand in terms of speed.

Ease and Flexibility

These apps provide access to built-in smartphone features, such as calendar, camera, microphone, GPS. Hybrid apps come with a limitation in this area.

Cons Of Native Application Development

With so many goodies, the native application also come with some limitations. Get to know in detail-

Cost of Development

The native developers are specialized in a single platform, either it is Android or iOS. Therefore, the businesses require a large development team, which burdens their pocket. Similarly, the updates or changes in the future will multiply the cost and team strength.

Increased Time

Native apps tend to require more development time than the hybrid ones. The reasons are quite obvious that you need to create app design for diverse dimensions of devices, such as iPhones, Android devices, tablets and more.

Define Hybrid App-


Hybrid applications are based on the web view. The web view runs on the web app within a native application. It makes use of native application wrapper, which sets up communication amid native device and web view platform.


Just like the native app, one can download the hybrid application from an app store. These applications are built with the tools, which further link native platforms to the web view and help them communicate. These are known as third party tools, such as Apache Cordova.

The developers use HTML, CSS, and JavaScript to build hybrid apps. It is named hybrid as it has two parts. The initial one is backend code, and the second one is native shell that converts them into a downloadable product.

Pros Of Hybrid App Development

Like native application, hybrid also owns some advantages, let’s know them in detail-

Fast to Market

We know that there is high competition in the app market, as a great portion of population uses smartphone. And, you need to combat this competition as same idea has been hit by your competitors in the store. If you want to introduce your app to the audience, then hybrid app is the best option, as it has fast entry record to the market.

Less Development Cost

Hybrid app allows you to remain budget-compliant. The reason is simple, you need to craft it once for each platform (Windows, iOS, Android). Therefore, you do not have to hire a big team of developers for each specific platform.

Hassle-free Maintenance

We are aware of the fact that hybrid application is a web application, which has been wrapped in the native shell. Hence, we can update the content multiple times according to the necessity. So, the maintenance of hybrid apps remains low.

Cons Of Hybrid App Development

Performance Glitch

Hybrid applications come with adding more layer between the mobile platform (mobile framework) and source code. This leads to slow performance or result in complete loss, but it is different for different applications.

Cold UX

In hybrid app development, it is challenging to manage a superb UX between the iOS and Android application. If you give more attention to the user experience of Android, then the iOS one will get dead. Similarly, if we focus on the iOS UX, then the Android platform will have to suffer.

Hard to Go Debugging

The additional layer of hybrid development framework puts extra pressure and debugging becomes hard to handle. The developers have to trust themselves with the used operating system, being extra cautious regarding bugs.

Comparing The Two Hybrid and Native

The difference between hybrid and native applications is quite clear with their definition, pros and cons. Native app is for a single platform while hybrid app runs on diverse platforms. Both of these platforms require different skills to code, manage and work. Hybrid and native apps are different in terms of features, technology, usage and performance. But, they both are crucial, in terms of their speciality. And, their usage will keep expanding due to the increasing number of mobile users across the world.

To get to know the differences in detail, we are sharing a table, check it out-

Wrapping Up

With definition, features, advantages and disadvantages of both native and hybrid applications, it will become easier for you to pick the right one for you business app. If you still feel confused, then the best approach is to create a list according to your business goals, target users and priorities. Now, you have a proper list of specifications, tally both native and hybrid app development approaches. When you are done with re-thinking, it is time to make an educated decision. If you want to get a proper consultation from a mobile app development company, then you can book a consultation session. Once you feel completely assured, you can go ahead with your final decision.

In today's highly competitive market playground, businesses – small or big – must find ways to stay ahead of the curve. With mobility and mobile-dependence increasing at an exponential rate each day, a mobile app is definitely one of the sure-fire ways to for a business to widen its reach and gain considerable influence over the market. Given these facts, a mobile application should therefore be built with the utmost care to not let it fade into insignificance among the hundred thousand other apps that are in the market.

Given today's fierce competition, hiring a mobile app developer or agency requires a careful vetting process that involves knowing exactly what you should need and expect from them. To that end, here is a list of five questions that you should ask a prospective app development company that you are planning to hire.

5 Questions to Ask Before Hiring Mobile App Developers


1. What is your previous experience? Can I see a published app from your portfolio?

This should be one of your primary concerns while taking on a new developer. Knowing how long they have been in the business can give you an idea of how capable they will be of taking your app on. In addition to that, asking them about apps that have been published will give you an assessment of their ability to give you exactly what your business needs. A good developer/agency will provide these details, complete with working app store links, with no hesitation.

2. Can I speak directly to a few of your previous clients?

Word-of-mouth and personal recommendation can do far more for a company's standing than anything else. Ask your prospective agencies for some of their recent references. Talking to their clients can help you gauge the kind of relationships they forged during the projects: will they be responsive enough when you need them to be or if are they realistic in setting up their milestones and sticking to them? Any reluctance to provide these freely is a red flag.


3. Tell us about your communication strategy during development.

One of the major factors that will determine the success of your app is your agency's ability to understand your business objectives thoroughly. A good company will ask a good number of questions, to ensure they are on the same page as you. They will not leave anything up to interpretation or assumption. During the development process, they will keep an open channel of communication to show you that all your requirements are being addressed and any roadblocks they run into are honestly conveyed during the process.

4. What are the core services you offer during development?

A good development team will offer everything from business analysis, development, QA beta testing and even, marketing. One key factor you need to also look at is the amount of importance that is given to making your app's design. Remember, that no matter how unique your app is, if the UI is clunky and difficult to use, it will not succeed. Extensive research on a company's previous projects is always a good idea: do the products they have developed comply with the latest standards? Do they have experience working with the latest tools and frameworks for development?

5. Will you provide any post-development/release support?

As we've said before, you need a long-term contingency plan for your mobile app. What comes next after your app has been published is probably just as, if not more, crucial. Bug-fixes and improvements will be inevitable, and you'll need to be able to address them as soon as you can. The longer the post-development support offered, the better you can trust their reliability.

Finding the right developer for your project does indeed come with a fair amount of risks, and in a way, does need a certain amount of trust to go with it. But, going in forearmed and forewarned will aid you in discerning what's right for your project.

Developing a mobile app without knowledge of any programming language is not easy if there were not any such tools called app builder on the internet. If you search on Google, you may find 100s of app builder but they all are not good. Some of them only convert your mobile friendly website to a simple html5 app. That means they only add an icon to your website to display on smartphone and simple other tasks. Some of them offer same service with some extra simple builder features but are worthless.

If you want to make an app for your business or other purpose you must have developer account to publish apps on Google Play Store or Apple Apps Store that costs around $124 ($99 for Apple and $25 for Google Play). So even if you are looking for a free apps builder, you must spend that amount and plus brand identity of your apps builder and their advertisements. Some of free apps builders may give you access to build your app at free of cost but they charge when you want to publish so don’t look for free instead look for a good builder that offers lowest maintenance fee.
