iOS app development agency FAQ

How long does it take to build an app?

The completion of your application depends on several factors. First, developers take into account the scope of work, which incorporates features, external integrations, customisation of UI/UX design and animation, and device compatibility. Typically, the duration is the following:

— 1-3 months for a simple application

A static mobile program with only a few screens, minimal back-end, and elementary navigation will allow your users to leave notes and check what they’ve done.

— 3-6 months for a middle-level app

Functionality like user authentication, notifications, payment gateways, and custom animations for your clients to track their progress, study, or plan events.

— 6-12 months for a complex utility

Scalable infrastructure that grows with the number of users and operations, real-time data processing, and offline mode to access the app without the Internet.

Limeup adjusts to desired delivery dates by expanding the iOS app development team and following Agile principles to deliver on time without letting quality slip.

How to choose the right iPhone application development company?

You will reach your revenue goals, get access to a wide range of Apple device users, and turn them into paying customers if you cooperate with a capable crew of developers. Acting according to the plan we specified below, you will find experts who will realise your idea:

  • Define your goals. Ascertain that the software supplier you will join forces with has mastered the technology you require, such as Objective-C, Swift, Xcode, Interface Builder, Python, and many others, especially if the app is not simple.
  • Research providers’ background. Check the vendor’s trustworthiness. This encompasses visiting its website, reading testimonials on independent websites, and inspecting registration and legal aspects.
  • Evaluate their success stories. Look at what the agency for iOS development has already done. Assess designers’ prowess, partnership outcomes, and project them onto your idea to decide whether it aligns well.

When seeing that the iPhone mobile application development company is trustworthy, has a good grasp of the tech you are interested in, and demonstrates a positive track record, book a consultation and test its communication.

Can Limeup help modernise or upgrade our existing iOS app?

Limeup can supply you with comprehensive support regarding your current application to optimise its performance. Our developers will audit the code and remove inefficiencies in order to increase the reliability and readability of your app.

We will redesign your app to simplify navigation, allowing users to quickly learn how to use it with simple training and shorten the checkout process to boost sales. Apart from that, designers will craft up-to-date screens and make the application accessible to satisfy different categories of users.

To support your expansion initiative, our iOS application development company will rebuild your application infrastructure, connect it with cloud solutions to store data efficiently, and integrate third-party enhancements to prepare your app to process more operations without slowing down.

Finally, if you plan to add recommendations based on user behaviour, personalisation, filters, location, offline mode, and any other new functionalities, we will tailor the solution to suit your business needs.

  • Advanced tech expertise. A British company building iPhone apps has strong skills in artificial intelligence, data analytics, machine learning, and cybersecurity.
  • High industry knowledge. You will receive first-class applications with all necessary features across fintech, healthcare, education, and other high-stakes sectors.
  • Regulation compliance prowess. Many development firms from the United Kingdom secure perfect FCA, UK GDPR, App Store, HIPAA alignment.

What type of businesses benefit most from iPhone app development services?

The large group of people who use iOS devices represents a potential client base for many businesses, with no limitations. Whether you prefer subscription or in-app purchases, specialists from a custom iOS app development company will bring your vision to life.

However, the businesses that operate in the following way have all the chances to establish a good presence and attract more customers:

The e-Commerce apps that give purchasers the opportunity to buy items quickly and effortlessly, while offering a high level of personalisation, gain attention from those who choose iPhones.

Connecting with iOS mobile app development services providers can help deliver high-quality healthcare and wellbeing through health tracking tools, video conversations, doctor appointments, and fitness exercises. This can enable clinics and individual specialists to reach new, loyal customers online.

Unlocking access to secure and reliable finance and banking apps with investment perks, real-time updates, multiple payment options, and simple onboarding will find great acceptance among iPhone users.

Fast data processing gives a boost to businesses in the education sector. Gamified and animated applications with progress updates have high ranks on App Store.
