We build mobile and web apps.

It's the engineering of consumer and enterprise surfaces — iOS, Android, web, sometimes desktop — built to production consumer-software quality and integrated with the real infrastructure a Web3, AI or fintech product needs. This category requires specific integration expertise: embedded-wallet flows, streaming AI UIs, stablecoin payment rails, App Store review preparation for crypto apps, biometric and passkey authentication, and analytics tied to product-specific metrics rather than generic page views.

Cost is driven by platform choice, platform count, integration depth, real-time or offline requirements, polish target and platform-review complexity — not feature count, which teams consistently overestimate. Native iOS is one build; iOS plus Android native is 40-60% more; adding web is a third codebase. Cross-platform reduces platform-count cost but adds integration friction for deep-native features.

Native when deep platform integration, polish or App Store positioning dominates; React Native when the team is JavaScript-native and cross-platform parity matters; Flutter when animation fidelity or Dart-native expertise justifies it. React Native is the default for most 2026 cross-platform builds — Expo and EAS tooling has matured, and Hermes engine performance is strong. Native remains the right answer for premium consumer products or deep-platform-integration requirements.

Product surface engineering, navigation and IA, authentication and onboarding including embedded-wallet flows, data layer and state management, integration to your product backend, performance tuning, App Store and Play Store submission preparation, CI/CD for releases, observability and design-system implementation. The backend product itself stays yours — we integrate, not build the protocol or AI model — and App Store review outcomes are Apple's and Google's decision, not ours to guarantee.

We default to Privy, Magic or Dynamic for most consumer Web3 apps in 2026 — they've solved onboarding friction without requiring users to manage seed phrases. The shape: a user signs in with email, social or passkey, a wallet is created silently, and it's controlled by a combination of device keys and cloud-backed recovery. WalletConnect runs as a parallel path for users who already have a wallet, and recovery flows are designed explicitly for the 'lost phone abroad' case.

Through specific framing choices, close adherence to App Store Guidelines on crypto and financial services, accurate privacy-manifest disclosures, and avoiding patterns that trigger rejection. The most common rejection reasons are in-app-purchase bypass, unlicensed financial-services framing and inaccurate app descriptions. We pre-review submissions against current guidelines and test with TestFlight — first-submission approval on our crypto apps runs above 95%.

For most developed-market consumer crypto products, iOS drives more revenue per user. For most emerging-market products across Southeast Asia, MENA, Latin America and Africa, Android drives the majority of users. The right split depends on target market — platform priority should match your target user base, not developer convenience.

Native earns its place when you need the device — biometrics, secure key storage, push, NFC, camera, offline behaviour. Crypto, fintech and anything holding credentials usually qualify immediately. Where the experience is mostly content and forms, a strong responsive web build reaches everyone instantly with no install step and no review queue. Many products are best served by web first and native once usage justifies it. We scope against what your product actually needs from the hardware, not against a default.
