Custom mobile app development services that ship on time and pass App Store review.

iVentureTeam offers end-to-end custom mobile app development — native iOS (Swift, SwiftUI) and Android (Kotlin, Jetpack Compose), cross-platform with React Native and Flutter, enterprise mobility apps connected to Odoo, ERPNext, Zoho, and SAP, AI-powered mobile features, app modernization and migration, plus App Store Optimization and 24/7 post-launch support. We engage as fixed-price builds, dedicated mobile dev teams, or focused modernization sprints.

Mobile app development cost depends on scope, platform count, design complexity, and integrations. As a guide: an MVP single-platform app typically lands between $25K–$60K, a cross-platform feature-complete app between $45K–$120K, and an enterprise ERP-connected mobile app from $80K upwards. We give a written fixed-price quote after a 30-minute discovery call.

Most production-grade mobile apps ship in 10–16 weeks from discovery to App Store submission. MVPs with a narrow scope can launch in 6–8 weeks. The duration depends on platform count, backend complexity, third-party integrations, and the QA bar you want. We commit to a milestone schedule before kickoff and report against it weekly.

Native (Swift / Kotlin) is best when you need the deepest platform integration — biometric flows, ARKit, complex animations, or strict performance requirements. React Native and Flutter are excellent for most business and consumer apps that need both iOS and Android with a tight budget and timeline — you save roughly 35–45% versus building two native apps. We give a written recommendation based on your specific feature list, not a one-size-fits-all answer.

Yes. Every engagement includes Apple App Store and Google Play Store submission as a standard deliverable — preparing assets, writing copy, ASO keyword research, screenshot generation, and managing the review back-and-forth with Apple and Google. We also handle phased rollouts and staged releases so you can monitor production health before going 100%.

Yes — this is one of our strongest differentiators. We connect mobile apps to Odoo, ERPNext, Zoho One, SAP, Salesforce, HubSpot, and custom backends in Node.js, Laravel, Django, or .NET. We design clean REST or GraphQL API contracts, build secure auth (OAuth 2.0, SSO, biometric), and handle offline-first sync where the field requires it.

Yes. We sign NDAs on request before the first call and structure every engagement so that you own 100% of the source code, design files, infrastructure accounts, and ASO assets. Everything lives in your repos and your cloud accounts from day one. No vendor lock-in, no hidden dependencies.

Yes. Every fixed-price build includes 30 days of post-launch hypercare. Beyond that, we offer monthly support retainers covering crash response (4-hour SLA on critical), OS-version compatibility updates, App Store Optimization reviews, quarterly feature releases, and analytics-driven roadmap reviews. You can also extend the dedicated team model for continued development.

Yes. We run focused modernization sprints — a written code & architecture audit, crash and performance benchmarks, a prioritized fix backlog, and sprint-based remediation. Common projects: Cordova or Ionic apps migrated to React Native or Flutter, Objective-C ported to Swift, Java codebases refactored to Kotlin, and consolidation of two native codebases into a single cross-platform build.
