Mobile App Development Services
for iOS & Android.
Mobile app development services from Stpeternwok Inc. — native, hybrid, or cross-platform, built, tested, and launched on the App Store and Google Play.
Native, Hybrid, or Cross-Platform?
This decision shapes your budget, timeline, and how your app feels — so it's worth getting right from the start.
Maximum performance
Built separately for iOS and Android, using each platform's own tools — the smoothest experience, at a higher cost.
One codebase, both platforms
Faster to build and more budget-friendly, with a small trade-off in performance compared to native.
A practical middle ground
Modern frameworks that get close to native performance while still sharing most of the code.
Mobile App Development, Start to Launch
iOS App Development
Apps built and optimized for iPhone and iPad, meeting Apple's design and performance standards.
Android App Development

Cross-Platform Apps
One app, built once, running on both iOS and Android — ideal for faster launches on a tighter budget.

Post-Launch Support
Bug fixes, OS updates, and feature improvements, so your app keeps working as platforms change.
From Idea to App Store
Discovery & Planning
We define your app's core features and decide whether native, hybrid, or cross-platform fits best.
Design & Prototype
We design every screen and flow, so you can see and test the app before development begins.
Build & Test
We build the app and test it on real devices, not just simulators, to catch issues before launch.
Launch & Support
We submit the app to the stores and stay on for updates as your user base grows.
Built for Real Business Needs
E-Commerce
A dedicated app for browsing, ordering, and tracking — built for repeat customers, not just first visits.
Service & Booking Businesses
Letting customers book appointments and manage bookings directly from their phone.
Real Estate

Healthcare
Appointment booking, reminders, and secure communication with patients.

Custom tools for your own team — inventory, field reporting, or internal workflows.
Apps Built to Actually Ship
Built for your actual needs
We recommend native, hybrid, or cross-platform based on your goals — not whichever is easiest for us to sell.
Tested on real devices
We test on actual phones across screen sizes, not just simulators that miss real-world quirks.
We stay on after launch
Apps need updates as operating systems change — we don't disappear once it's live.
Mobile App Development FAQs
Native apps offer the smoothest performance but require separate code for iOS and Android. Hybrid and cross-platform apps share one codebase, which is faster and more cost-effective, with a small trade-off in performance. We'll recommend the right fit based on your app's complexity and budget.
Cost depends on app complexity, the number of features, and whether you need iOS, Android, or both. After understanding your idea, we give you a clear, upfront quote rather than a generic price range.
Yes. We build native apps for each platform separately, or a single cross-platform app that runs on both, depending on what best fits your goals and budget.
A focused app with core features typically takes 8–12 weeks. More complex apps with custom backends or integrations take longer, depending on scope.
Yes. We handle the full submission process, including store listings, screenshots, and meeting each platform's review requirements.
Yes. We offer ongoing maintenance covering bug fixes, OS updates, and feature improvements, so your app keeps working as phones and operating systems change.
