iOS app development
Applic offers a full cycle of native iOS app development in Swift — from concept to App Store publication and post-release support. Fixed cost. Transparent timelines. Our own in-house team, no outsourcing.
We pass the App Store review on the first try: we know the requirements by heart and don't waste weeks on rejections due to minor technical issues.
For whom
Which businesses benefit from iOS app development?
Developing iOS apps is an investment with measurable returns. If your business targets Apple's mobile audience, the app becomes a direct sales and communication channel — with no intermediaries such as social media algorithms or ad auctions.
If your customers are an urban audience aged 25–45 with above-average income, they most likely own an iPhone. 70% of iOS users make an in-app purchase within the first hour after installation. Conversion is 20% higher than on Android equivalents. Mobile app development for iPhone is especially relevant for:
Ecommerce and marketplaces
Apple Pay, quick checkout, push notifications about promotions
Fintech and banking
Face ID, secure transactions, built-in integration with Wallet
Medicine and Health
HealthKit, stringent data security measures, accurate measurements
Service sector
Bookings, payments and CRM right in the customer’s pocket
B2B platforms
Internal tools for teams: tasks, reports, approvals
EdTech
Interactive content, user progress, lesson notifications
Media and publishing
Native content apps: news, podcasts, social media integration

Advantages
What benefits an iPhone app brings to your business
The App Store generates nearly twice the revenue of Google Play.
With a smaller audience.
Building iOS apps means entering an ecosystem with a high level of user trust. Creating an iOS app means getting into a store with no junk — and users know it. iOS app development requires meeting strict standards Apple — and it's precisely this strictness that works in your business's favor.
A good app becomes part of daily habits. Deleting it is harder than forgetting to open a website
Push notifications are read more often than email and SMS — a direct conversation with the customer at the right moment
Subscriptions, in-app purchases, ads and affiliate programs — the App Store's mature infrastructure
The App Store's strict standards mean a bug-free app with predictable behavior — which affects ratings and retention
Behavioral analytics unavailable via a website: usage patterns and the conversion funnel
An App Store app built to Apple's standards signals serious intent
Ecosystem
Developing for Apple: ecosystem specifics and their impact
Apple is a closed ecosystem uniting iPhone, iPad, macOS, Watch and TV. Every app goes through manual review: Apple's team checks it against the guidelines. It takes time, but it filters out low-quality software — which is exactly why users trust the App Store.
Custom iOS app development means working with specific rules. We know them thoroughly: we avoid App Store rejections and launch faster. Thorough testing before every release is our mandatory standard.
Our record: first-time publication for 9 out of 10 new apps
Process
Stages of custom iOS app development
A transparent process with fixed milestones — the client always knows what's happening, what's next and how long it will take. The most common request from new clients: 'the previous team didn't communicate' — we've fixed that systematically
Market analysis and concept development
⌄We start not with code but with understanding the goal. Who your user is, how they behave, what they look for in an app. We analyze competitors on the App Store: what works and where the gaps are. Here we also define the monetization model — paid app, freemium, subscription or in-app purchases. The choice of model affects architecture and design.
Even if you only have an idea, our specialists will help develop it into a clear concept using proven tools and methodology.
Drafting the technical specification
⌄The spec is the contract between everyone involved. We lock down functionality, screens, navigation logic, integrations, the stack and performance requirements. We also define which iOS system capabilities are needed: Push Notifications, Location Services, Camera, Face ID or Apple Pay.
The more precise the spec, the more predictable the timeline and cost. No 'well, we meant something a bit different' halfway through development.
Design
⌄UI/UX in Figma: wireframes, prototypes, final mockups. Everything is approved before development begins. The design follows the Human Interface Guidelines — the app looks native to iOS, not a layout ported from Android.
We also work through edge cases: what happens with no internet, what the user sees on first launch. Good UX cuts code-stage revisions several times over — and speeds up the whole project.
Testing and app QA
⌄We test on real devices across different iOS versions — not just simulators. Functional tests, regression, load, edge cases. Separately — performance testing: launch time, rendering speed, behavior on a weak connection.
Apple analyzes performance metrics during review. An app that lags on an iPhone 12 risks rejection regardless of functionality. We catch bugs before release, not after.
Publication
⌄We prepare metadata, screenshots, description and keywords for the App Store. We pass Apple's review — with our experience that's 1–3 days. If rejected, we analyze the reason and resubmit without delay. Usually the first or second attempt is enough.
On request we help with ASO — App Store search optimization so your app is found organically.
Technical support
⌄In our experience, most revisions and rework happen precisely because details weren't agreed at the start. We close that off at the spec and prototyping stage — saving both money and nerves later on.
After launch we stay with the project. We monitor crash reports, ship updates for new iOS versions, and add functionality per the roadmap. Apple releases a major iOS update once a year, each with new capabilities and changed requirements. Without support an app degrades: first visual artifacts, then warnings, and within a couple of years — forced removal from sale. Most of our clients work with us for several years in a row.
Technologies
iOS development tech stack
We use only a native iOS stack — no Ionic, React Native or Flutter — when the task demands maximum performance and full access to Apple's system APIs
Swift is a modern, safe language and significantly faster than Objective-C. Native code runs faster, uses less battery and delivers a flawless UX.
For projects that need cross-platform mobile apps for iOS and Android at once — we use Flutter or React Native. Learn more: mobile app development.
We use Objective-C only to maintain legacy code. For new projects — Swift exclusively. Unlike JavaScript frameworks, Swift compiles to native machine code — giving maximum speed and full access to Apple's system APIs with no intermediate layers.
Why us
Why clients choose our team to build iOS apps from scratch
Building iOS apps from scratch is more than just code. Our approach is built on understanding the Apple ecosystem, experience passing review, and product thinking. We don't outsource the project: all development is done in-house — managed quality, predictable timelines and direct accountability for the result.
Over the years we've learned the main thing: a good iOS app starts with the right questions at the outset, not with rushing into development.
Swift, SwiftUI, UIKit — direct access to all of Apple's system APIs. Not wrappers over web technologies
Task tracker, regular demos, interim builds for you to test yourself. No black boxes
We know the requirements by heart. We don't lose weeks to rejections over technical details
We ask the uncomfortable questions upfront: why the app, who will use it, how we'll measure success
Long-term partnership is our standard, not an option

Real Problems - Real Solutions
East-West Air Cargo
22+ years of partnership
Challenge: Toyota dealers received cars for service without recording the condition of the bodywork. After servicing — disputes with customers over scratches that 'appeared at your place'.
Solution: a mobile app for a 360-degree vehicle inspection right at the intake point. An employee walks around the car, photographs any damage, and the client signs the report on a tablet. All data is sent to the dealer's system in real time.
Result: Disputes over vehicle condition — zero. Intake processing time dropped by 35%. Data was never lost throughout the entire time in operation. The partnership has been going for 22+ years.
Contacts
Ready to discuss your project?
Tell us about your goal — we'll send a proposal back within 1–2 business days. The first call is free, commits you to nothing, and usually makes it clear exactly what needs to be built.
We work both on new products from scratch and on projects that need refinement or expansion of an existing app. If integration with external systems is needed — CRM, ERP, payment gateways or local services such as LiqPay or the Nova Poshta API — that's a standard task for our team. We don't disappear after release: we remain a partner for the product's entire lifecycle.

Frequently asked questions about iOS app development
How much does iOS app development cost?
⌄For iPhone app development, the cost comes down to three factors: the number of screens, the complexity of the business logic, and the scope of integrations. The price is always fixed in the contract — no surcharges along the way. A precise estimate follows the Discovery stage, with the spec and architecture locked down. You get a predictable cost from day one.
What are the iOS development timelines?
⌄An MVP for a single platform — from 6 weeks. A standard product with design, native development and basic integrations — 3–5 months. Enterprise solutions with multiple roles and complex logic — from six months. We fix timelines in the contract and don't change them without the client's agreement. App Store review takes 1–7 days; we build that into the release plan so the launch date doesn't slip at the last moment.
Which devices does iOS app development cover?
⌄By default — iPhone from iOS 15, which covers over 95% of active devices. iPad app development is a separate task, with adaptation for the large screen, split-view and keyboard shortcuts. If both form factors are needed, we design a universal app with separate layouts. Apple Watch and Apple TV are separate platforms with their own SDK; we develop for them on request.
Do you provide support after the project?
⌄Yes. We sign an SLA for technical support: crash reports, updates for new iOS versions, and adaptation to App Store changes. Support is long-term — most of our clients work with us for several years. We respond to critical bugs within the business day and plan scheduled updates in advance — before Apple changes its requirements.
Who is iOS app development right for?
⌄Businesses with an audience on Apple: ecommerce, fintech, healthcare, B2B, EdTech. We deliver projects at any stage — from a raw idea to scaling a finished product. For startups — building iOS apps from scratch with no technical debt and no upselling. For companies — creating iOS mobile apps to automate internal and customer-facing processes.
iOS app development on Windows is possible via cloud CI/CD pipelines — we set them up on request. Ordering an iOS app from us is simple: write to us, we'll reply within one business day and ask the right questions before any contract is signed. Building iPhone apps natively delivers maximum performance — cross-platform is faster and cheaper at the start; we'll honestly explain what suits you best.
