iOS App Development Services

iOS (backed by Apple) is the most popular operating system, primarily designed for mobile phones. The company has also developed a number of iOS variations to power up other gadgets like tablets, TVs, and wearables. iOS, watchOS, and tvOS are the biggest competitors to the Google-backed mobile operating system - Android.

Design Principles

iPhone & iPad

Custom iOS app development is all about exceptional user experience which is a hallmark of Apple products, and a distinctive feature of the most successful startups built for iOS, OS X, watchOS, and tvOS

Clarity Created with Sketch.


Throughout the system, all texts are readable at every size, icons are sharp and lucid, adornments are subtle and coherent. Functionality governs the design. Colors, fonts, interactive elements and negative space facilitate to convey interactivity and highlight the essential mobile content.


Every iOS app development company knows that content is paramount. Crisp, non-distractive interface helps users to interact with the content without competing with it. Blurring and transparency hints at more. Bezels, gradients and drop shadows are used in modesty to create an airy and light feeling of the interface.

Depth Created with Sketch.


Hierarchy is created with distinct visual layers and realistic motion. Touch functions enable access to additional functionality and satisfy the crave for discovery by presenting additional content. Seamless transitions offer a sense of depth as you navigate through the app.

Apple Watch


Make the key information readily available to the user. Interactions happen instantly, hence the app must render the most important information up-front and without any side distractions. Take advantage of the custom notification interface as a glanceable app is meant to deliver up-to-date information straight from the watch face.


The onscreen information should be always up-to-date and relevant. Use background time to obtain real-time data, refresh snapshot and update its complication. Actionable apps try to anticipate the user's needs and should include custom actions to deal with common tasks without opening the app.

Responsive Watch Created with Sketch.


All the snapshots should be kept up-to-date. All the in-app interactions should be quick and smooth. Minimize the time to load new screens and fetch new data. The app should respond immediately to user interactions with a feedback of what it's doing, and afterwards deliver progress updates.

Apple TV


Apple TV stands for rich, mesmerizing, cinematic experience. Touch surface of the remote conveys the same feeling of touching an iOS device screen. Achieve the sense of complete immersion through visually stunning imagery, fluid animation, engaging content and delightful audio.


Siri Remote enables content interactions through touch surface, gyroscope and accelerometer. Everything is done via intuitive, flowing gestures. Content can be modified with a swipe, click, tap or a flick of the wrist.


Content for Apple TV should feel intuitive. Users should immediately understand what to do and where they are at any time. Make the text readable at a distance, use the provided grid layout and avoid clutter with all means. All the interactions happen via remote navigation. A certain element is considered in focus when it is highlighted, not clicked.
