Mobile Applications
App Developers
Canada, USA & Europe
iOS and Android apps built to product-level standards — not templates. App developers you can hire in Montreal, Toronto, and across Canada, the US, and Europe. Our bilingual team delivers mobile experiences that users actually keep.
What we build
iOS Native Applications
Swift-based iOS apps built to Apple's platform standards — fast, precise, and App Store ready from the first submission.
Android Native Applications
Kotlin Android apps optimized for the full range of Android devices — from Material Design to performance-critical use cases.
Cross-Platform Apps (React Native)
One codebase, both platforms. React Native with near-native performance — the right call for most product teams building under budget and time constraints.
MVP & Prototype Development
Scoped tightly to validate your product hypothesis — built to ship, not to impress investors on a slide deck. Real users, real feedback.
Mobile Backend & API
Authentication, push notifications, data sync, payment integration — the backend your app needs, built to scale from launch to growth.
App Store & Google Play Launch
End-to-end store submission — certificates, metadata, screenshots, compliance review — handled as part of every delivery. No handoff chaos.

Our process
Product Discovery & Scoping
We map your user flows, platform requirements, and commercial logic before writing a line of code. You receive a clear scope document with timeline and platform recommendation — not a ballpark estimate.
UX Design & Prototype
Wireframes and interactive prototypes reviewed and approved before development begins. Platform-specific UX patterns applied — not generic web UI adapted for mobile.
Development & QA
Sprint-based delivery with working builds at every milestone. Device testing across iOS and Android versions — not just emulators. You see progress throughout, not a reveal at the end.
Launch & Post-Launch Support
App Store and Google Play submission handled end-to-end. Post-launch monitoring, crash reporting, and iteration support included in every engagement — not an extra contract.
Who we work with
Early-stage startups
Building your first app? We scope MVPs tightly, choose the right platform, and deliver something you can actually test with users — not a six-month black box.
Product companies
Expanding your web product to mobile? We design and build the mobile experience as a product — not a port — with the UX and performance it deserves.
Established businesses
Modernizing a legacy app or launching a new mobile product line? We handle complex integrations and existing backend architectures with the precision they require.
EN / FR commercial orders
We accept commercial app development orders from companies in Montreal, Quebec City, Toronto, Paris, Brussels, and across North America — across Canada, the US, and Europe — fully bilingual from brief to delivery.
FAQ
Frequently asked questions
Do you build both iOS and Android apps?
Yes. We build native iOS apps (Swift), native Android apps (Kotlin), and cross-platform apps using React Native. The platform decision is made based on your audience, performance requirements, and budget — defined in a discovery session before development begins.
Should I choose React Native or native development?
React Native is the right call for most products: it reduces development time and cost significantly while delivering near-native performance across both platforms. Native Swift or Kotlin is recommended for apps requiring intensive hardware access, complex platform-specific animations, or strict App Store performance thresholds. We advise based on your specific requirements.
How long does mobile app development take?
An MVP or functional prototype: 4–8 weeks. A fully featured app with backend, authentication, payments, and dashboards: 8–16 weeks depending on scope. Every engagement starts with a discovery session that produces a clear, milestone-based timeline before a single line of code is written.
Do you handle App Store and Google Play submission?
Yes. We manage the full App Store and Google Play submission process — certificates, metadata, screenshots, privacy labels, and compliance review — as part of every delivery. No separate contract, no handoff to the client mid-process.
Do you accept mobile development orders in French?
Yes. Voronkin Studio is a fully bilingual agency (EN/FR). We communicate, document, and manage projects in both English and French. We regularly work with clients in Montreal, Quebec City, Paris, Brussels, and Switzerland — agence développement application mobile bilingue.
