Professionally designed UX/UI

From web portals to native mobile apps

We develop modern digital applications that users access from web browsers (Chrome, Safari) or downloadable mobile apps (App Store, Google Play). Includes: advanced corporate websites, client portals with complex features, e-commerce, mobile apps for clients or employees, Progressive Web Apps (PWAs).

Difference with enterprise software development: Enterprise software (child 1) is typically for internal use, operations management, limited users. Web/mobile apps are for broad audiences: clients, general public, field teams. They prioritize user experience (UX/UI), attractive design, performance, accessibility from any device.

Modern stack: We use modern JavaScript frameworks (React, Angular, Vue), native mobile development (Swift/Kotlin) or cross-platform (React Native, Flutter), API-first backends (Node.js, .NET Core), scalable cloud infrastructure. Result: fast, responsive apps with professional user experience.

When do you need web or mobile app?

Modern digital presence for clients

Current corporate website is outdated (10+ years), not responsive (mobile), loads slowly. You need modern professional presence.

Self-service portal for clients

Clients call/write for simple queries (balances, invoices, order status). Self-service portal reduces operational load 40-60%.

Mobile app for field team

Salespeople, technicians, delivery personnel working outside office. They need mobile app for: order capture, service reports, tracking.

E-commerce or marketplace

Sell products/services online. Digital channel that operates 24/7 without human salesperson. B2C (end consumer) or B2B (businesses).

Digital platform that IS your product

Startup or digital company where app IS the business. Not support tool; it's the main product you sell or monetize.

Internal app with real-time data

Executives/managers need mobile access to dashboards, KPIs, approvals. App complements enterprise system with mobile access.

5 types of web/mobile apps we develop

  • Expanded geographic reach
  • Sales cost reduction
  • Client behavior data
Examples:
  • B2C online store

Best forComplex apps, gaming, AR/VRMost enterprise apps

Choose Native if:

  • Critical performance (gaming, video, AR)
  • You need cutting-edge OS features
  • Budget allows
  • Only 1 platform (iOS or Android only)

Choose Cross-Platform if:

  • Standard enterprise app
  • Moderate budget
  • You need iOS + Android
  • Time-to-market is critical

Our experience: 70% of projects use React Native (cross-platform), 30% native. React Native covers 90% of use cases perfectly at 50% of cost.

Frequently Asked Questions

Depends on complexity and scope: Simple app (5-10 screens, basic functionality, no complex integrations): $15K-$35K. Medium app (15-25 screens, API integrations, custom backend, login/users): $35K-$80K. Complex app (30+ screens, advanced features, AI/ML, payments, real-time): $80K-$200K+. Web app: Typically 60-70% cost of mobile (less testing, no App Store). We estimate accurately after discovery session where we understand scope.

Development: 3-5 months typically. Simple app: 2-3 months. Complex app: 5-8 months. Publication in App Store/Play Store: 1-2 additional weeks (Apple/Google review). Total: 3-6 months from kickoff until app available for download. Critical factor: clear scope definition at start accelerates everything. Significant scope changes during development can extend timeline 30-50%.

Depends on your audience. LATAM data: iOS ~20-30% market share, Android 70-80%. If B2C (consumer): We recommend iOS + Android from start (you don't lose 70% of market). If B2B (businesses): You can start with platform that dominates your target client and add second later. Recommendation: React Native (cross-platform) gives you both for cost of 1.5X one native. Better than making one native now and another in 6 months (duplicated costs).

Depends on design. Apps that CAN work offline: Apps with local data (catalogs, downloaded content), data capture apps (forms, photos) that sync later, reading apps (news, documents). Apps that require internet: Apps with real-time data (social media, trading), transactional apps (payments, transfers), collaborative apps (chat, video). We design appropriate offline strategy according to your case: complete offline, partial offline (read-only), or online only.

We do both. Complete UX/UI design included: User research, wireframes, professional visual design, interactive prototype. UX/UI designers on team. Difference vs agencies that only design: We design AND develop, ensuring design is technically viable and implemented faithfully. Difference vs developers that only program: We don't use generic templates; custom design adapted to your brand and audience. If you already have designs from external agency, we can implement them too.

Post-launch includes: 3 months support (bug fixes, minor adjustments), security updates, compatibility with new iOS/Android versions. After 3 months: Optional maintenance contract (according to complexity): Periodic updates, new features, user support, monitoring, optimizations. Apps require continuous maintenance: OS updates (iOS 18, Android 15), third-party APIs change, bugs arise with massive usage. Without maintenance, app degrades in 12-18 months.
