Mobile App Development

Q: How much does it cost to build a mobile app?

Mobile app development typically costs between $50,000 for a focused MVP and $300,000 or more for a complex enterprise application. Key cost drivers are platform choice (native iOS and Android costs more than cross-platform), feature complexity, design requirements and backend infrastructure. Scrums.com uses transparent usage-based pricing, so you see exactly where every sprint hour goes.

Q: How long does it take to develop a mobile app?

A well-scoped MVP takes 3 to 4 months from discovery to App Store launch. A full-featured application with multiple user roles, backend integrations and custom design typically takes 6 to 9 months. Complex enterprise applications can take 9 to 12 months or longer. We work in two-week sprints so you see working builds continuously.

Q: What is the difference between native and cross-platform development?

Native development uses platform-specific languages: Swift and SwiftUI for iOS, Kotlin and Jetpack Compose for Android. It delivers the best performance and access to the latest platform features, but requires two separate codebases. Cross-platform development with React Native or Flutter uses a single codebase for both platforms, with faster time to market and lower cost for most B2B and SaaS applications.

Q: Should we build for iOS or Android first?

If your target market is the US or Western Europe, or revenue per user is a priority, start with iOS. For global reach or emerging markets, Android has broader reach. If budget allows, cross-platform development with React Native or Flutter lets you launch on both platforms simultaneously at lower overall cost.

Q: Do you offer ongoing mobile app maintenance after launch?

Yes. Mobile apps require continuous maintenance for OS updates, security patches, bug fixes and feature enhancements. We offer monthly maintenance plans with proactive monitoring, fast response times and no lock-in contracts.

Q: Who owns the code and intellectual property?

You do, 100 percent. All code, designs, assets and intellectual property produced for your mobile application are yours from day one. No licensing restrictions, no proprietary frameworks and no data lock-in.

Q: Can you take over an existing mobile app project?

Yes. We pick up incomplete projects, maintain apps built by other teams and modernise legacy mobile applications. We audit the current codebase, identify risks and technical debt, and build a plan for completion or modernisation. Most maintenance takeovers complete within a week.

Scrums.com delivers your iOS, Android and cross-platform apps as scoped workstreams on the Scrums.com platform: fixed milestones, SLA-backed, shipped to both stores and maintained after launch. You pick the scopes; Scrums.com owns the outcome, with AI agents reviewing, testing and watching every release.

AI-native mobile app development on the Scrums.com platform

Mobile app development on Scrums.com is an outcome you buy, not a team you manage. Each app is delivered as a workstream made of scopes from the register: a launch sprint, a native build, a maintenance plan, each with a fixed milestone and an SLA. The work runs on the SEOP platform with AI automation across the delivery lifecycle: agents that review code, run QA and watch releases, all governed through one gateway. A workstream is live in under 21 days.

/01

Real-time delivery visibility

Sprint progress, working builds and usage-based billing in one dashboard from day one. You see where every hour goes.

/02

Agents inside the SDLC

QA agents, code-review agents and release monitoring run on the platform, so the human team spends its time on product, not on toil.

/03

Your tools, your cadence

The team plugs into your existing repositories, ticketing and CI. Stack changes are recommended only when they materially improve delivery outcomes.

Mobile app maintenance and DevOps after launch

Keep iOS and Android applications secure, performant and compatible with the latest operating systems and devices. OS compatibility updates ship two to four weeks before Apple and Google launch, so the app never breaks when users upgrade.

Maintain Application maintenance

Bug fixes and issue resolutionCrash reports monitored, issues reproduced and fixed, critical bugs typically inside 48 hours.
OS compatibility updatesBeta releases tested and deprecated APIs updated so your app keeps working when Apple and Google ship new versions.
Performance optimisationLoad times, animations, memory and battery efficiency measured and improved continuously.
Security patchesAdvisories monitored, dependencies updated, encryption improved, GDPR and CCPA compliance kept current.

DevOps Release and observe

Monitoring and analytics24/7 crash detection, performance tracking and real-time dashboards for app health, error rates and API response times.
Release pipelinesApp signing, store metadata, compliance checks and staged rollouts run as a repeatable process, not a scramble.
Third-party SDK updatesPayment, analytics and platform SDKs kept current as part of the maintenance plan.
Feature enhancementsIterative improvements from user feedback and analytics, shipped without disturbing stability.

The build is under $30K

Mobile app engagements typically start at $50K+. A no-code or low-code tool may fit smaller scopes better.

You need a single specialist, not a team

If you have a mobile team and need one more engineer, hire from the register instead. Hire AI engineers →
