Build Secure, Scalable, and Delightful Mobile Apps — Native, Cross-Platform, or Hybrid
At Innosaber, we design and deliver custom mobile apps that solve real business problems and delight users. From consumer-facing apps to complex enterprise mobile solutions that integrate with CRMs, ERPs, payment systems, and IoT devices — we build end-to-end mobile products for iOS, Android and modern cross-platform stacks.
What We Build
- Consumer mobile apps (B2C) — marketplaces, social, lifestyle, fintech, travel, media.
- Enterprise mobile apps (B2E/B2B) — field service, sales enablement, asset tracking, inventory, HR systems.
- Mobile-first web apps & PWAs for users on any device.
- Connected apps that integrate with backend APIs, microservices, third-party SaaS, IoT, BLE devices and on-prem systems.
- E-commerce & payment apps with secure checkout, wallets and payment gateway integrations.
- MVPs & prototyping to validate ideas quickly and iterate.

Step-by-step Mobile App Development Process (We Follow Scrum)
We follow an agile Scrum approach with iterative sprints so you get early value, frequent demos, and predictable outcomes.
1. Discovery & Product Strategy
- Stakeholder interviews and business goals.
- User research, personas, and competitive analysis.
- Define core features, KPIs and success metrics.
- Deliverable: Product brief, prioritised feature list, high-level project plan and estimates.
2. Architecture & Integration Planning
- Choose the right platform(s) (native vs cross-platform) based on UX needs, performance, time-to-market, and budget.
- Define system architecture: backend services, data flow, offline strategy, sync & conflict resolution, and security controls.
- Identify third-party integrations (ERP, CRM, payment gateways, push providers, analytics).
- Deliverable: Technical architecture diagram, API contract definitions, data model.
3. UX & UI Design (Mobile-first)
- Map user journeys and create task flows.
- Low-fidelity wireframes → interactive high-fidelity prototypes (Figma).
- Mobile UI system & component library (design tokens, accessibility specs).
- Deliverable: Clickable prototypes and design system ready for implementation.
4. Sprint Planning & Setup
- Break features into user stories with acceptance criteria.
- Set up project board, environments (dev/staging/prod), and CI/CD pipelines.
- Provision accounts for App Store Connect and Google Play Console (we assist if needed).
5. Incremental Development (Sprint-by-sprint)
- Implement features in short sprints (1–2 weeks) — front-end UI, business logic, background sync, secure storage.
- Backend work: APIs, auth, push, file storage, serverless functions or microservices as required.
- Implement offline-first behaviour and data sync patterns if needed.
- Continuous integration, unit tests, and automated builds every sprint.
Daily Scrum ensures alignment and quick removal of blockers.
6. Quality Assurance & Testing
- Functional testing, device & OS fragmentation testing, cross-network testing.
- Automated unit tests, integration tests and end-to-end tests (as applicable).
- Performance testing (including cold start time, memory usage, and battery consumption) and network behaviour.
- Accessibility testing (screen reader support, contrast, large text).
- Security testing (OWASP Mobile Top 10 checks, secure storage, encryption in transit & at rest).
7. Beta Releases & User Acceptance Testing
- Distribute to internal testers and early users via TestFlight (iOS) and Google Play Internal/Closed testing tracks.
- Collect feedback, crash reports, and telemetry; iterate quickly in subsequent sprints.
8. App Store & Play Store Submission
- Prepare build, metadata, localised descriptions, screenshots, and privacy policy.
- App signing, provisioning, and compliance checks.
- We handle submissions, remediation of store review issues, and follow-up until approval is received.
Launch & Post-Launch Monitoring
- Production rollout strategy (phased rollout, feature flags).
- Monitor analytics, crash reports, performance and user feedback.
- Hotfixes and immediate patches as required.
Ongoing Support & Roadmap
- Regular maintenance (OS updates, dependency upgrades), feature releases, and A/B testing.
- Optional managed support and dedicated teams (full-time/part-time) for continuous delivery.
Integration Patterns & Backend Connectivity (Practical Details)
- API-first approach: design robust, versioned REST or GraphQL APIs with clear contracts.
- Real-time & Sync: WebSockets or Socket.IO for chat/real-time features; background sync and conflict resolution for offline apps.
- Push Notifications & In-app Messaging: tailored campaigns and deep links to drive engagement.
- Secure Authentication: token-based auth (JWT), refresh tokens, secure storage (Keychain, Keystore), biometric auth (FaceID / TouchID / Android Biometrics).
- Payment Flows: client-side payment UX with server-side verification and webhooks for reconciliation.
- Third-party SaaS: CRM (Salesforce), ERP, analytics or marketing automation integrations with secure middleware.
- IoT & Hardware: BLE, NFC, GPS, camera/scanner integrations and telemetry ingestion.
Security, Privacy & Compliance
- Data encryption in transit (TLS) and at rest.
- Secure key management and secret rotation.
- GDPR, CCPA and local data residency considerations — we advise on compliance and consent flows.
- Penetration testing and security audits upon request.
Testing Matrix & Device Coverage
- Physical devices + cloud device farms (BrowserStack, Firebase Test Lab) to ensure wide coverage across OS versions and form factors.
- Focus on both high-volume device profiles and edge cases for target markets.
Delivery Models & Resourcing
- Fixed Scope (Project-based): Great for well-defined app builds with clear deliverables.
- Dedicated Team / Resource Augmentation: Hire Innosaber engineers (full-time or part-time) to embed with your team — ideal for long-term product evolution.
- Hybrid: Fixed price for MVP + dedicated resources for ongoing feature development.
We provide developers, mobile architects, QA engineers, DevOps and product managers — matched to your technical needs and budget.
