The decisions that decide the outcome

A Great iOS App Starts With the Right Product Decisions

Many mobile projects struggle because development starts before the product scope, user journeys, technical architecture, integrations, and release requirements are properly defined.

  • 01 Unclear MVP scope
  • 02 Poor onboarding
  • 03 Complicated UX
  • 04 Slow performance
  • 05 Unstable APIs
  • 06 Legacy code
  • 07 Security gaps
  • 08 Difficult releases
  • 09 Weak analytics
  • 10 Poor App Store readiness
  • 11 High maintenance costs

  • Information architecture
  • User journeys
  • Wireframes
  • High-fidelity UI
  • Design system
  • Navigation
  • Forms
  • Empty states
  • Loading states
  • Error handling

Native or cross-platform is a decision, not a default. We choose it against your product's requirements, platform needs, integrations, release strategy, team skills, and who maintains it long-term — see the comparison further down this page.
Backend & API integration

Connect Your iOS App to Your Business Systems

REST APIs

Secure, predictable, well-defined interfaces, with network failures handled gracefully rather than silently.

Authentication

Accounts, sessions, tokens, and role-based access, aligned with the identity system you already run.

Databases & Cloud

Data services and managed cloud infrastructure sized to the workload the app actually generates.

Payment Gateways

Payment flows appropriate to the business model, including the platform's own requirements where they apply.

Maps & Location

Location-aware workflows with permission handling that makes sense to the user at the moment it is requested.

CRM & ERP

Connecting the app to the business systems of record instead of building a second version of your data.

Booking & Inventory

Availability, scheduling, and stock, with the consistency rules that keep mobile and back office in agreement.

Messaging & Webhooks

Event-driven updates, file and media storage, and third-party services wired in with retry and failure handling.

The Apple-specific part

Take Advantage of the Apple Ecosystem Where It Adds Real Value

Depending on the product, the app can use platform capabilities that improve usability and engagement. The test is always whether a capability solves a real user or business problem — not whether it is available.

Push notifications

Timely, relevant messages with the permission prompt asked for at a moment the user understands.

Deep links

Routes straight into the right screen from email, web, campaigns, and other apps.

Camera

Capture, scanning, and document workflows where the phone replaces a manual step.

Location

Location-aware features with an accuracy and permission level matched to the actual need.

Biometrics

Face ID and Touch ID for fast, secure access to accounts and sensitive workflows.

Secure device storage

Keychain and secure storage used where credentials or sensitive values need to live on-device.

Share & calendar

System share sheets and calendar-related workflows that fit how people already use the device.

Siri & Shortcuts

Voice and shortcut entry points where a repeated task is worth automating.

Apple Pay

Where applicable to the business model, a checkout path with far less friction than a card form.

iPhone

The default target for consumer products: one-handed reach, compact navigation, and layouts that hold up from the smallest supported screen to the largest.

iPad

A genuinely different design problem, not a stretched phone screen — multi-column layouts, dashboards, and the field and productivity workflows where the larger screen is the point.

Security & privacy

Build With Security and Privacy in Mind

Both are considered throughout product design, engineering, API integration, testing, deployment, and maintenance.
Secure authentication
Authorization
Token handling
Encrypted communication
Secure local storage
Keychain usage
Input validation
API protection
Least-privilege permissions
Sensitive-data handling
Dependency updates
Monitoring

Privacy is a deliverable on iOS, not a policy page

Apple requires you to declare what data the app collects, why, how it is used, and whether it is linked to the user or used for tracking. Answering that accurately means knowing it before submission, so we work through it as part of the build:

  • What data the app collects, and which of it is genuinely needed
  • Why each item is collected, and where it goes
  • What third-party SDKs collect on your behalf — usually the part that surprises people
  • Which disclosures and user controls the target market requires
Performance & reliability

Deliver Fast, Stable Experiences Across Supported Apple Devices

Performance is measured across the actual device and OS range the product supports — including the oldest device still in scope, which is usually where problems appear first.

Performance focus

  • Startup time
  • Memory usage
  • Network efficiency
  • Image/media optimization
  • Battery impact
  • Smooth scrolling
  • Caching
  • Background work
  • Large-data handling

Reliability focus

  • Crash monitoring
  • Error logging
  • Retry strategies
  • Poor-network handling
  • Graceful failure
  • Production monitoring
Testing & quality assurance

Validate Every Critical User Journey Before Release

The critical journeys get tested explicitly: onboarding, login, search, forms, checkout and payment, booking, notifications, account management, data synchronization, and offline or poor-network behaviour where the product needs it.
  • Functional testing
  • UI testing
  • API testing
  • Integration testing
  • Regression testing
  • Device testing
  • OS-version testing
  • Network testing
  • Performance testing
  • Security testing
  • Accessibility testing
Analytics & product insights

Use Product Data to Improve the iOS Experience

Analytics reveals where users activate, engage, convert, drop off, or return — which is what should decide the next release, rather than whoever asked loudest.

Events worth instrumenting

Install/open Sign-up Login Feature usage Search Product view Add to cart Booking Payment Subscription Content interaction Notification interaction

What we watch

  • Activation
  • Engagement
  • Retention
  • Conversion
  • Feature adoption
  • Funnel completion
  • Crash rate
  • Session performance
App Store

Prepare Your iOS App for a Confident App Store Release

Release preparation covers technical configuration, testing, store assets, metadata, privacy disclosures, submission, rollout, and post-launch monitoring.
01

Release configuration

Build settings, signing, certificates, provisioning, and versioning set up so releases repeat cleanly.

02

Store listing

Description, keywords, screenshots, and metadata prepared for the listing rather than written the night before.

03

Privacy information

Data-collection disclosures and permission usage strings that match what the app genuinely does.

04

Test distribution

Builds distributed to your team and testers for sign-off before anything is submitted.

05

Submission

The production submission itself, prepared against the current requirements, including what reviewers need to test the app.

06

Monitoring

Crash reporting and release monitoring from day one, with a defined route for the first patch.

We can't promise App Store approval, and neither can anyone else. Review is Apple's decision and the guidelines change. What we do commit to: preparing the submission against the current requirements, flagging anything in the product that is likely to attract a rejection before it is built, and handling review feedback if it comes back.

Existing apps

Modernize Legacy iOS Apps for Today's Users and Technology

Legacy applications become costly when architecture, dependencies, UI patterns, APIs, testing, or security practices fall behind. A rebuild is one option, not the only one.
Architecture improvements
Dependency updates
UI modernization
API modernization
Performance optimization
Security improvements
Technical debt reduction
Automated testing
CI/CD improvements

We audit the existing product first, identify the business-critical and high-risk areas, and then choose incremental modernization or a controlled rebuild. Where the work spans more than one app or a wider legacy estate, that sits on our app modernisation and integration page.

Choosing an approach

Native iOS or Cross-Platform? Decide It Before the Design Starts

This choice affects cost, timeline, team, and what the app can do. It is much cheaper to make deliberately at the start than to revisit after the first release.
Native iOS favours
  • Deep use of Apple platform capabilities and hardware
  • Products where interface polish is a competitive advantage
  • Demanding performance, graphics, or media requirements
  • iOS-first audiences, common in premium and enterprise segments
Cross-platform favours
  • Launching on iOS and Android together on one budget
  • Mostly standard UI over API-driven content
  • MVPs that need to reach real users quickly
  • Keeping features identical across both platforms
Why choose us

FAQs

Have a question? We have the answer. If you don't see your question here, feel free to reach out to us.

Do you build custom iOS applications?

Yes. We design and develop applications around your business workflows, users, product goals, and integrations.

Can you build both iPhone and iPad apps?

Yes. The interface can be designed for the supported device categories and use cases. iPad is treated as its own design problem rather than a scaled-up iPhone layout.

Can you build an iOS MVP?

Yes. We can prioritize the highest-value product workflows for an initial release and hold the rest for later.

Can you integrate my existing backend?

Yes, where suitable APIs or integration mechanisms are available. Where they are not, that work becomes part of the scope rather than a surprise mid-project.

Can you integrate payments?

Yes, using appropriate payment technologies and providers based on the business model and platform requirements.

Can you modernize an existing iOS app?

Yes. We can assess architecture, dependencies, UX, performance, security, and technical debt before recommending modernization or a rebuild.

How long does iOS app development take?

Timelines depend on product scope, workflows, integrations, backend work, testing, and release requirements. We estimate after discovery rather than before it.

Can you help with App Store submission?

Yes, release preparation and submission support can be included. Approval is Apple's decision and the guidelines change, so we prepare against the current requirements and handle review feedback rather than promising an outcome.

Do you provide post-launch support?

Yes. Support can cover compatibility updates, bugs, performance, security, monitoring, and feature enhancements.

Can one backend support both iOS and Android?

Often yes. A well-designed API and backend can serve multiple clients, subject to the product's requirements.
