Success Stories from our Global Clients
Our Core Strength as an iOS Mobile App Development Company
1
Full-cycle iOS Development
We work with you as a full-cycle partner, not just writing code to specifications. Together with you, we create native iOS products from start to finish: discovery, UX, roadmap, MVP, growth, and scaling. This approach helps you launch your product faster, stay within your budget, and avoid redeveloping the same product because key decisions were missed at the beginning.
2
Apple Ecosystem Mastery
From Human Interface Guidelines and App Store readiness to Dynamic Island, widgets, App Clips, Apple Watch, Sign in with Apple, and Apple Pay, we develop features for your app that improve adoption, retention, and conversion while staying in line with Apple's expectations.
3
iOS apps built for real use
For connected products, iOS is often the primary interface between the user and the device. We create companion apps for fitness, health, EV, and IoT, providing reliable BLE connectivity, complex integrations, and real-time synchronization.
4
Modernization with zero disruption
If you have legacy iOS code, that's no reason to stop your development. We help modernize Objective-C/Swift apps, reduce technical debt, and transition to modern approaches (Swift/SwiftUI) without stopping the product. You continue to implement improvements without stopping your business.
5
Stable senior teams
You work with experienced iOS engineers and a stable team, not with constantly changing freelancers. Our developers undergo a rigorous selection process (only 0.3% of applicants work with us) and have been with us for an average of more than 3 years. You can be sure that our team is deeply immersed in the context of the work and will not change in the middle of important processes.

FAQ
Which company develops iOS?
iOS apps can be created by a development company specializing in Swift and cross-platform development. At Stormotion, we have deep expertise in the Apple ecosystem and practical experience in creating reliable, secure, and scalable mobile solutions on iOS.
How much does it cost to develop an app for iOS?
The cost of developing an iOS app depends on several factors in different iOS app development companies. These include the scope, complexity, and whether you need only iOS or the entire ecosystem (back end, admin panel, integrations). Creating an MVP iOS app costs approximately $30,000–$80,000, while a complex iOS product will cost around $180,000+ (connected hardware/BLE, real-time synchronization, WatchOS, complex backend, enterprise security, significant upgrades).
