Android & iOS Mobile App Development

Introduction

Launching a high-performing app in 2026 takes more than a tech stack. You need to scope the product, prioritize features, ship fast and clean, and sustain quality over time.
At FlexiApps, we design, build, and publish Android & iOS apps ready for the stores, using a proven method (Discovery → UX/UI → Development → QA → Release → TMA) with clear commitments on performance, security, and scalability.

In short: you get an Android & iOS app that’s reliable, measurable, and built to evolve—within your budget and timeline.

Why Android & iOS in 2026?

• Maximum user coverage: Android and iOS remain essential to reach the global market.
• Higher UX expectations: load times, smooth interactions, offline access, and animation quality.
• Compliance & security: data encryption, identity management, App Store/Google Play requirements, GDPR.
• Data-driven product: instrumentation (analytics, crash reporting), A/B tests, faster iterations.

Our delivery method

Discovery & scoping

• Product vision workshop and business goals
• Personas, key journeys, feature prioritization
• Backlog for V1 and roadmap (MVP → iterations)

UX/UI design

• Wireframes and interactive mockups
• Design system (guidelines, components)
• Prototyping and user tests

Android & iOS development

• Choosing native or hybrid depending on performance, budget, and time-to-market
• Modular architecture, API-first, third-party integrations (payments, SSO, CRM/ERP)
• Automation: CI/CD, pre-prod builds, code reviews

For a deeper tech trade-off, see our cross-platform page.
For strict performance/hardware needs, see Native mobile development.

QA & security

• Unit, integration, functional, and E2E tests
• Performance metrics (render time, memory, cold start)
• Security: encryption, hardening, GDPR, permission reviews

Release & ASO

• Preparing assets (visuals, copy, privacy labels)
• Submission to App Store and Google Play
• Optimized product pages (ASO) and feedback loop

Maintenance & enhancements (TMA)

• SLA for corrective/evolutive work
• Monitoring (crash-free sessions, stability, OS compatibility)
• Roadmap for continuous improvement (features, UX, performance)

Typical features

• Authentication (email, social login, SSO) and roles
• Payments (in-app, local gateways, subscriptions)
• Push notifications, messaging, engagement
• Geolocation, maps, routing
• Offline mode (sync, network resilience)
• Analytics, crash reporting, feature flags
• Integrations with ERP/CRM, PIM, CMS, third-party tools

Costs & timelines: what drives them

• Functional scope and UX complexity
• Integrations (payments, SSO, business systems)
• Performance level (animations, offline, older devices)
• Security & compliance requirements
• Launch strategy (pilot, progressive rollout)

FAQ (2026)

Q1. Native or hybrid: which should we choose?
A. It depends on priorities. For maximum performance or deep hardware access, native may win. For faster time-to-market and budget efficiency, hybrid is often ideal. We decide during Discovery.
→ See Cross-platform mobile development and Native mobile development.

Q2. How long to ship a V1 ready for the stores?
A. Typically 10–16 weeks depending on scope, integrations, and QA. A smaller MVP can launch sooner if we reduce initial scope.

Q3. Who handles App Store and Google Play submissions?
A. FlexiApps prepares assets, assists submissions, and sets up a baseline ASO to maximize adoption.

Q4. Can you take over an existing app?
A. Yes. We audit code/performance/security, propose a remediation plan, then take over TMA.

Q5. What performance & quality guarantees do you offer?
A. Code reviews, CI/CD, automated tests, crash-free monitoring, LCP/INP/CLS objectives, and production monitoring.

Q6. How do you address security and GDPR?
A. Encryption, hardening, consent management, data minimization, logging, and incident plans.

Q7. How do you estimate the budget?
A. We run a scoping workshop to assess scope, risks, and integrations. You receive a phased estimate (MVP, V1, evolutions) with options.

Q8. Do you offer a maintenance contract (TMA)?
A. Yes — corrective/evolutive SLA, OS updates, device compatibility, and continuous optimization.
