Why iOS app development, though?
Project Manager

Revenue increase

Comparing mobile OS, one thing becomes vivid at once - in terms of revenue, iOS is the leader. In spite of the fact that a startup setup requires plenty of funds, choosing iOS as the main OS for mobile development is a decision that potentially can bring a lot of profit. One of the main reasons is the iOS users’ preferences. Thus, they spend more money on in-app purchases. Design the app properly, make people like it, and need the purchases, and the revenue increase will follow pretty soon. One thing still should be kept in mind. To reach this goal, you should hire an experienced iPhone developer.  


One Of the peculiarities of iOS is that there's great compatibility within the ecosystem between devices. So the development is faster and clearer in the end, with fewer compatibility issues.

Better UX

iOS is a platform, that had all the chances, possibilities, and needed tools to deliver smooth UX consistent enough to make people love the product. Add here innovative functionality which can be implemented, and it will become absolutely clear why clients prefer iOS. All these force touch, peek and iPencil support can be leveraged with the help of the iPhone app development services we provide.

Improved Security 

Comparing iOS and Android in terms of security,   it is clear that iOS is the winner here because user data protection is in focus for Apple. It is also one of the reasons why, statistically, Android devices become targets for hackers and attacks more often than iOS devices. They are simply more vulnerable.

Software Capacity

Apple users almost don’t deal with fragmentation because more than half of them use the latest iOS version. For Android, these numbers are somewhere around 10%.

Things to keep in mind while choosing an iOS app development company?

Among the factors to be included, a special attention should be paid to: 

  • Reputation of the company

  • Past projects and active ones from the portfolio
  • References from the customers 
  • What services the company provides.

According to the statistics Manifest has recently provided, more than 30% of users delete the apps from their devices because they do not use them often enough. And more than 25% say that they delete apps because their needs are not fulfilled properly. There’s a way to overcome this issue, though. And it is custom iOS app development that helps with the main issues the users face. The key to success is that very approach we have mentioned earlier. Everything is created from scratch and is closely connected to the project. It is exactly what happens when Celadon experts start working on iOS mobile app development services. They use deep analysis, building the project with pleasant UX and smooth flow at the end that will be liked by users and will fulfill their needs.

Why are clear processes that important in iOS development?
Project Manager

A high-quality and consistent product can be delivered if only the team follows a step-by-step approach starting from the ideation stage. However, the past-release support adds scores when you are choosing the company to work with. Clear processes mean that the customer’s requirements are considered and strictly followed and the results of the work are provided. Celadon is a good example of a custom iOS app development company  having a time-proven development process. And it includes all the points we have highlighted in the previous paragraphs. However, we make sure that your requests for Apple iOS app development are understood and defined correctly because we use workshops for better interaction.
