Now that you’ve read about the top app development companies in California, here’s a few frequently asked questions to help you understand the services and various other technical terms associated with the industry.

What’s the difference between iOS, Android app development?

iOS and Android are two different smartphone platform. They don’t share anything common but you need to build applications for both of these platforms to cover the most ground in terms of smartphone users.

iOS development is pretty restricted as it is a closed project owned by a private corporation. You can only develop native iOS applications using Apple devices.

On the other hand, Android is an open-source platform which comes with a lot of freedom. You can develop applications on any OS including Linux and MacOS. Android’s ecosystem is also the largest in the market today. So, you definitely don’t want to miss out on that.

Eventhough the applications for both of these platforms may look similar but Android applications are often more affordable to get develop.

What’s the difference between a website and a web application?

The main different is the functionality and features that comes with both types of online real estate.

A website can be anything from a blog, business website or a portfolio and so on, but a web application can be a custom built SaaS application, social media app, e-commerce platform and so on.

Usually, a web application is much more expensive and demanding to get develpoed. You may need to spend a lot of time doing research and perfecting the user-experience.

Some websites don’t need any type of feature updates. Once launched, you don’t need to update it for a very long time but with a web application, you don’t regular updates, be it feature updates and security patches.

With new browser updates and updates in the programming platforms and server OS, it becomes necessary to update the application to work seamlessly with these technologies.

Do you need a web application if most of your customers are only going to use mobile applications?

Yes, despite of all the rumors that websites and web applications are obsolete, a good chunk of users still prefer using websites to make important purchase decisions.

Even if that’s not the case, using technologies such as Flutter and React Native, you can easily transform your mobile application into a fully functional web application.

This way you’ll have a full coverage and maximum ROI on your marketing spend.

What’s the difference between native and hybrid/cross-platform application?

A native application is built specifically for a platform. For example, a native iOS application will only work with iOS mobile operating system.

Hybrid and cross-platform application, on the other hand, can be modified to work on both iOS, Android and web browsers.

This makes them an attractive offering specially, when you have to pay a hefty sum to get native applications developed. With hybrid app development technologies, you can get one app developed using React Native and deploy three different version that would work perfectly fine with any given OS and platform.

What’s the main difference between iOS and Android applications stores?

When it comes to quality and security, nothing even comes close to Apple’s App Store. The added layer of security comes from the restrictive nature of Apple’s online assets and it’s mobile operating system itself.

Unless the device is rooted, which also revokes the warranty, it is virtually impossible to infect, bypass the security and install a foreign application

Furthermore, iOS has a pretty long list of terms and conditions when it comes to deploying applications on their app store. So, if your application doesn’t meet their quality standards, it will get rejected.

Now, let’s talk about Android’s Play Store.

Play Store is a relatively easy-going marketplace. Since Android is an open-source platform, security is on the lower side and the risk of getting the virus and other malicious applications.

You can install applications from any third-party source without rooting the device. So, Google’s TOS and security standards remains a gimmick.

Hiring locally and remotely?

If you are from the US or North America, chances are that your local app development companies would charge 4-5 times more than what a remote app development company would charge.

That said, there are pros and cons of hiring from both locally and remotely. Here’s a few of them:

Pros of hiring locally:

  • You can meet them and schedule a team meatup whenever you feel is convenient.
  • Confidentiality and data protection.
  • Many finance and healthcare businesses prefer local brands due to several underlying security, privacy and legal reasons.

Cons of hiring locally:

  • You have to pay a hefty sum to get your application developed
  • Development team is also dependent on the same work days and other holidays.

Pros of hiring remotely:

  • The cost of production is relatively low.
  • There are some very talented minds that can help you in developing complex software solution without breaking a sweat.
  • Some app development companies also offer round the clock development to fasttrack the development process.
  • You can also make use of their team extension and other DevOps services to help you get an extra set of hands on the desk.

Cons of hiring remotely:

  • Data protection is a concern and you don’t know what the work conditions are.
  • Legal documents sometimes need to be signed in-person. Having a remote team can delay the production timeline.
  • Some financial organizations and healthcare industries require you to hire locally, so hiring a remote team becomes a bit hectic.

What’s the average cost of developing mobile applications?

Somewhere from $10,000 to Millions of dollars. The range might seem a bit wide but that’s how the market places their services.

The actual cost of developing an application will depend on the type of application, industies, number of features and the brand.

So, the best way to get an estimate is to get in touch with the app development agency for a free consultation. Most brands don’t have a static pricing plans. So, depending on your needs and requirements, the charges may be increased or reduced.

How would you update your applications?

Well, most companinies offer post-deployment services and maintenance services. You can make use of them and if you want to hand over the future updates to some other company, you can do that as well. Most app development agencies usually offer software maintenance services.

When should you deploy updates?

There are three major types of application updates:

  • Security updates
  • Version updates
  • Feature updates

And all three of these are very necessary and should be rolled out on a regular basis.

Both Android and iOS platforms get regular updates and upgrades. If your applications isn’t upgrades or updated as per the latest OS iteration, some or many features may stop working rendering user-data and other sensitive information vulnerable.

Furthermore, app development is not a one-time job, you will have to refresh the app design, collect data from the user to improve user-experience, add or remove features and more.

What’s the development process behind a simple application development project?

An app development process can be very simple or complex depending on the complexity of the project. If your project demands extensive research and testing, the process will reflect that and your overall production rate will also be longer.

A simple development process includes:

  1. Consultation
  2. Research
  3. Project planning
  4. Assigning team members
  5. Development
  6. Quality Assurance
  7. Deployment
  8. Maintenance and after-sales support

If you hire an agency for a complete digital makeover or digital transformation, keep in mind that it might take longer as they are not only helping you renovate your mobile apps, but also help you with renovating your website and other software systems.

How would you communicate with remote app development companies?

Most companies already have some sort of communication channel that they use to get in touch with their clients for briefing and explanation.

You can use from a number of software and cloud applications such as Zoom, Skype, Google Meet and many more.

When should you expect your application to be deployed?

It might take months on end to get an application developed. There are some companies that offer ready to launch applications that can be rebadged and launched within a few days but those only work well with basic businesses and regular e-commerce companies.

If you are a creative startup that needs to develop a state of the art application, you will have to wait for at least 4 to 6 months.

Please note that it’s better to let the development team take their time than forcing them to build an application ASAP.

Deploying applications with loopholes and bugs will turn off your customers and negatively impact your applications reputation.
