We build mobile apps the same way modern products ship — fast, secure, and ready to scale. Whether you need an MVP to test a market, a production-grade app for customers, or to wrap an existing web app into iOS/Android using Ionic or Capacitor, our team designs, develops, and deploys it for real users, not just store screenshots.
Services
Cross-Platform App Development (React Native, Flutter, Ionic/Capacitor)
One codebase, native experiences. We optimize startup time, bundle size, and platform-specific UX so your app feels at home on iOS and Android.
Native iOS & Android
Swift/Kotlin for when you need the last mile of performance, device integrations, and platform-specific capabilities.
API & Backend Engineering
Secure REST/GraphQL APIs, real-time features, and scalable backends (Node.js, Python, Firebase/AWS/GCP). Includes auth, rate limiting, and observability.
UX/UI & Product Design
User journeys, wireframes, design systems, and clickable prototypes that translate cleanly into production.
QA Automation & Release Management
Unit/UI tests, device lab runs, beta distribution (TestFlight/Play Console), versioning, and crash-free sessions as a KPI.
CI/CD & DevOps for Mobile
Automated builds, code signing, environments, feature flags, and phased rollouts to cut release risk.
Maintenance, Monitoring & Growth
Crash analytics, performance dashboards, update cadences, and in-app experiments to improve retention and revenue.
Why FastStep Technologies
Why teams work with us:
- Product-first delivery – we don’t just “make an app”, we match it to your business flow.
- Cross-platform expertise – Angular/Ionic, React, Capacitor — we already work in this ecosystem.
- Performance-focused – we test LCP, bundle size, and loading time even in hybrid apps.
- Secure by default – token-based auth, secure API calls, and OWASP mobile best practices.
- Deploy anywhere – App Store, Google Play, private enterprise store, or as a PWA.
FAQs
Q1. Should we go native or cross-platform?
If you need top-tier performance, heavy device integrations, or complex animations, native may win. For most product-market-fit journeys, React Native or Flutter ship faster with excellent UX.
Q2. How long does a typical MVP take?
A focused MVP is often 8–12 weeks, depending on scope, integrations, and compliance.
Q3. Can you work with our existing backend?
Yes. We integrate with existing APIs or modernize them—adding auth, rate limits, and observability.
Q4. How do you handle app security?
OWASP-aligned reviews, secure storage, obfuscation/minification, code signing, and dependency audits.
Q5. What’s included after launch?
Crash/performance monitoring, scheduled updates, store compliance, feature flags, and A/B tests.
