What platforms do you build mobile apps for?

We build native iOS (Swift), native Android (Kotlin), Flutter, React Native, hybrid Ionic or Capacitor apps, and AI-powered mobile products. You can start on one platform and expand, or launch both stores from a single cross-platform codebase.

What maintenance is included after app launch?

Every project includes 30 days of post-launch support for crashes and minor fixes. Retainers cover OS compatibility updates, dependency patches, store monitoring, ASO iterations, and feature sprints month to month.

Will you sign an NDA for our mobile app?

Yes. Mutual NDAs are standard before sharing wireframes, APIs, or proprietary workflows. Your IP, source code, and store accounts stay under your ownership.

Mobile App Development | iOS, Android, Flutter & AI

Q: Flutter vs React Native: which should I choose?

Choose Flutter when you want a single Dart codebase with pixel-perfect custom UI on iOS and Android. Choose React Native when your team is JavaScript-first and needs OTA updates or deep React ecosystem reuse. We recommend the right stack in a free discovery call based on timeline, team skills, and native SDK requirements.

Q: How long does mobile app development take?

Most MVPs with 8 to 12 screens launch in 11 weeks: discovery and UX, build and API wiring, QA across devices, then App Store and Play Store submission. AI features, complex backends, or enterprise compliance add 2 to 6 weeks.

Q: Do you handle App Store and Google Play submission?

Yes. We prepare signed builds, privacy policies, content ratings, data safety forms, screenshots, and listing copy. Our team maintains a 100% first-submission approval track record by pre-checking policy issues before upload.

Q: How much does mobile app development cost?

Mobile app development is quote-based across MVP, Growth, and Enterprise plans depending on platform, screens, integrations, offline scope, and store work. No fixed public pricing. Written quote within 48 hours of discovery.

Q: Do you build AI-powered mobile apps?

Yes. We ship on-device and cloud AI: chat assistants, vision, voice, RAG copilots, and LLM integrations with guardrails, latency budgets, and App Store AI disclosure compliance.

Q: When should I choose hybrid app development?

Hybrid fits when a strong web team needs the fastest path into both stores with maximum code reuse from an existing web app. Tradeoffs include lower native fidelity and plugin limits versus Flutter or React Native.

Q: Native vs cross-platform: how do you decide?

Choose native iOS or Android when one platform needs deepest SDK access, graphics performance, or platform-only roadmaps. Choose Flutter or React Native when both stores matter and shared UI speed wins. We map tradeoffs honestly in discovery.

One Toronto team ships native iOS and Android, Flutter, React Native, hybrid, and AI-powered mobile apps with store submission, ASO, and post-launch support. Pick the right stack for your roadmap, not whatever framework your last agency preferred.

Native vs Flutter vs React Native vs Hybrid vs AI.

When to use each approach. We recommend honestly in discovery based on timeline, team skills, and SDK depth.

Stack	Best for	Typical timeline	Stores	When to choose
Native iOS / Android	Deep SDK access, platform-only roadmaps, max performance	10 to 12 weeks per platform MVP	One store native, or parallel native builds	Play Billing depth, HealthKit, graphics-heavy, or Android-only / iOS-only products
Flutter	Custom UI on both stores from one codebase	10 to 11 weeks dual-store MVP	iOS + Android together	Founders who need both stores fast with pixel-perfect branded UI
React Native	Teams with strong React / TypeScript skills	10 to 12 weeks dual-store MVP	iOS + Android together	OTA updates, web team reuse, and existing React component libraries
Hybrid	Web app reuse, internal tools, content apps	8 to 10 weeks to both stores	iOS + Android via Capacitor	Existing PWA or web product, limited native SDK needs, tight budget
