Deep integration expertise
We connect custom iOS apps to the systems you already run on — CRMs, ERPs, EHRs, legacy platforms, analytics, and internal portals. Integration is what turns an app into an operational tool, not an isolated product.
Custom iOS development for mid-market companies that need more than polished screens. We turn an app idea into a secure, integrated, scalable product that connects to your systems and supports real workflows.
Big agencies cost too much and move too slow. Small shops build a UI but stall on backend, compliance, and support. We built Yab to remove that trade-off.
Our iOS development is designed for companies that need apps connected to CRMs, ERPs, EHRs, inventory platforms, dashboards, and analytics. The goal isn’t just to launch — it’s to build an app that improves operational efficiency, increases engagement, and stays reliable long after release.
One company accountable for the complete lifecycle — backed by systems integration, portals, strategy, and ongoing support. Here’s what sets us apart.
We connect custom iOS apps to the systems you already run on — CRMs, ERPs, EHRs, legacy platforms, analytics, and internal portals. Integration is what turns an app into an operational tool, not an isolated product.
We design the user-facing app, the team-facing workflows, and the backend infrastructure together — essential in healthcare, life sciences, diagnostics, and B2B commerce where data, compliance, and reliability matter.
Our streamlined, parallel process cuts typical timelines by 30–40% versus slow sequential handoffs. Agile cycles keep development iterative and transparent, with clear milestones and regular updates throughout.
Native iOS built in Swift and SwiftUI, aligned to Apple's Human Interface Guidelines. Native means full access to device features and the performance and feel users expect from a first-class iPhone app.
A dedicated product manager keeps priorities, dependencies, milestones, and scope visible. Decisions don't vanish into an agency black box — you always know what's happening and what's next.
Industry-specific experience drives compliance and data-handling decisions. We build to GDPR and CCPA expectations and the Apple App Store Review Guidelines, so the app doesn't get rejected at the finish line.
End-to-end across the full app lifecycle — design, coding, testing, and deployment — with the app and the business systems built to be ready together.
A comprehensive audit of your systems, data flows, workflows, users, and app requirements — business goals, target audience, technical constraints, compliance needs, and App Store requirements. We define integration points, API requirements, data ownership, security expectations, and the architecture.
We build the iOS app while simultaneously creating the API connections, backend, middleware, dashboards, and admin tools — so the front end and the business systems are ready together. Testing runs throughout: devices, iOS versions, roles, workflows, data states, and edge cases.
App Store preparation, production deployment, infrastructure checks, analytics, and compliance review. After release we monitor engagement, performance, crash rates, and business metrics — then maintain and optimize as your users, systems, and market needs change.
If others offer disconnected app development, we offer connected digital transformation. If others hand complexity back to your team, we absorb it into a managed process.
Plenty of agencies design attractive apps; far fewer can connect them to complex business infrastructure. We bring mobile development together with systems integration, backend architecture, web development, and custom software.
Systems integration & APIsSenior mobile, iOS, and backend engineers, UX/UI specialists, and product managers — without enterprise-agency bloat. The global IT outsourcing market hit USD 587.2B in 2023; mid-market teams deserve that leverage too.
Built for apps that carry real work: referrals, orders, patient interactions, inventory, approvals, scheduling, field operations, and reporting — all backed by robust data orchestration.
How we orchestrate dataDesign isn't just appearance. Strong interface design helps users complete tasks faster, reduces the training burden, and drives long-term adoption — the difference between an app that ships and one that gets used.
AI-driven workflows, analytics, secure identity, real-time updates, Apple Watch experiences, and performance optimization — added when they serve the business case, never to inflate scope.
Practical AI strategyThe right proof is evidence an agency can deliver, handle integration, improve operational efficiency, and support clients after launch — not just a beautiful gallery.
Yab helped us turn a fragmented workflow into a mobile experience our teams actually use. The app reduced manual follow-up, improved visibility, and gave leadership the operational data we were missing.
The biggest difference wasn't just the iPhone app development. It was the way Yab understood our backend systems, compliance requirements, and internal users before writing code.
We needed an iPhone app development company that could move quickly without creating technical debt. Yab gave us clear milestones, regular updates, and a launch plan our internal team trusted.
If you want custom apps that improve workflows, support users on mobile, and create measurable growth — this was built for you.
Internal systems, multiple user roles, reporting, and approval workflows already in play. You need scalable solutions that connect the iOS app to existing operations — not basic mobile development.
Secure data handling, compliance readiness, auditability, interoperability, and reliable application development — alongside accessible experiences that meet WCAG standards.
Our accessibility standardMobile and web solutions for customers, vendors, sales, and logistics — iOS and Android apps, dashboards, inventory connections, and order management, tied into ERP and CRM.
B2B commerce platformsWorkflows tied to older software, spreadsheets, manual exports, or limited-API systems? We design integration layers that modernize the experience without forcing a risky full replacement.
Ranges to set expectations — final scope depends on integrations and complexity. We make ownership, environments, and support responsibilities clear before development begins.
Validate an app idea with core functionality, essential UX/UI, and basic system integration.
A complete iOS app with custom workflows, advanced features, integration, security, and a scalable backend.

Book a free strategy session. We’ll review your app idea, business goals, current systems, integration needs, target audience, timeline, and likely investment range — and give you a clear assessment of what it takes.
No long-term commitment. No vague promises. Just clarity.
The things teams ask before they build. If yours isn’t here, bring it to the strategy session.
Simple products with limited integrations may launch in a few months. More complex apps — with compliance, multiple user roles, backend systems, and legacy integrations — commonly require 4 to 9 months. The timeline depends on scope, feature complexity, number of integrations, data quality, approval cycles, testing needs, and App Store review.
Yes. We regularly collaborate with internal software teams, IT departments, product owners, security leaders, and external vendors. Yab can own the full app development process or support a specific part of it — iOS development, backend integration, UX/UI, web development, QA, or post-launch support. Our project managers keep communication clear so your team isn't buried in coordination.
That's one of the main reasons companies choose Yab. We audit your existing systems, identify available APIs, map data flows, document business rules, and design the right approach — custom APIs, middleware, adapters, or staged modernization. Legacy integration carries hidden dependencies, poor documentation, and security gaps, so we surface those risks early rather than discovering them after the app is built.
We design for maintainability, performance, security, and future growth from day one: modular architecture, clean API contracts, analytics, monitoring, automated and performance testing, and multi-device compatibility. We plan for new iOS versions so the app stays compatible as Apple evolves — and account for Android, Apple Watch, web portals, AI features, or new business units before they become expensive to add.
Operationally complex sectors where apps must connect to business systems and handle sensitive workflows: healthcare (secure patient workflows, care coordination, operational dashboards), life sciences and diagnostics (data integrity, regulated processes, field tools), and B2B commerce (customer apps, vendor portals, sales tools, ERP/CRM integration). We also support nonprofits and mission-driven organizations that need high-value mobile work without enterprise-agency overhead.
