Mobile App Development Services on a Managed Monthly Delivery Plan
Launch a mobile app your customers can use on iOS and Android, native or cross-platform with React Native or Flutter. Through the Delivery Plan, you get one team, one predictable monthly price and one prioritised backlog. Add web, backend, AI, data, QA or DevOps work to the same backlog whenever you need it.
Use your plan for mobile app development.
Trusted by engineering leaders at ambitious startups, enterprises and global brands.
Track every mobile app build on the Scrums.com Platform
Goals break down into tasks. Milestones are agreed before work begins. You track every build from requirement to the App Store, and the next task starts the moment one ships.
- Implementation
- Unit and UI tests
- Code review approved
- Build on TestFlight / internal track
How the mobile app development process works
What one workstream delivers, for mobile or any software
Your backlog can hold any number of requests, but the team delivers them one workstream at a time. A workstream is one managed team working on your highest-priority request until it is live, then starting the next. More requests mean more months, not faster delivery. Work is scoped and delivered within your plan’s capacity. Priorities can change; additional parallel workstreams require more capacity. The same plan covers web, backend, AI, data, QA and DevOps work, so all of it can share one backlog.
- Active at once
- One request
- Typical MVP
- 3 to 4 months
- Delivery
- Two-week sprints
- Code owned by
- You
Example: a React Native MVP on one workstream
Illustrative- Month 1Discovery and design, sign-in and account flows, CI/CD and store accounts set up.
- Month 2Core features: catalogue, search, order history and the backend APIs behind them.
- Month 3Payments, push notifications, device-matrix QA and analytics.
- Month 4Store submission, staged rollout and the first round of fixes from real users.
A sample customer app for iOS and Android from one codebase. It matches the 3 to 4 months a well-scoped MVP typically takes. Onboarding starts immediately after checkout, and your delivery owner scopes your own plan with you.
What affects the number of months
- Feature count and depthThe number of screens, user roles and edge cases in scope.
- IntegrationsPayments, identity, maps, legacy systems and third-party APIs.
- PlatformsNative iOS and Android builds take longer than one cross-platform codebase.
- DesignCustom interfaces and motion take longer than standard platform components.
- Starting pointA new build, an existing app, or a takeover that needs an audit first.
- Review and approvalsHow quickly your team signs off builds, and App Store and Google Play review.

Order and delivery tracking app
- Challenge
- Customers could not track their orders and flooded customer service with status calls. The service team had no view of driver locations or order statuses.
- Platforms and technologies
- React Native and Expo mobile app, a Vite-React and Chakra UI admin portal, AWS Lambda, AWS Cognito and AWS hosting, integrated with SAP.
- Work delivered
- Real-time order tracking with ETA notifications, driver geolocation with Google, multi-factor log-in with ID and OTP checks, and a central admin portal.
- Result
- Self-service order tracking cut inbound status calls. Management got real-time visibility of orders and drivers, and new features shipped every two weeks.

Mobile app development pricing
Core costs Was $8,000£6,700R140,000 now $4,500£3,750R79,000/month for one active workstream. Your app’s scope determines the delivery schedule and total cost. You can use the same subscription for other development priorities.
Best for companies building a new app, adding features to an existing app, or taking over a stalled project.
One plan for your software backlog.
Work is scoped and delivered within your plan’s capacity. Priorities can change; additional parallel workstreams require more capacity.
Mobile app development questions, answered
Still deciding? Talk to sales and get a scoped answer for your app.
Delivery Plan · Core costs Was $8,000£6,700R140,000 now $4,500£3,750R79,000 a month, excluding VAT or sales tax. That buys one active workstream with a managed mobile team. It is monthly delivery capacity, not a fixed price for a complete app, so your scope sets the number of months.
No. Was $8,000£6,700R140,000 now $4,500£3,750R79,000 a month buys one month of delivery capacity: one active workstream with a managed team. Your app’s scope sets how many months the build takes, and so the total cost. A well-scoped MVP typically takes 3 to 4 months; a full-featured app with multiple user roles, backend integrations and custom design typically takes 6 to 9 months. Infrastructure usage and third-party services are billed separately.
Yes. Delivery Plan · Core covers web, backend, AI, data, QA and DevOps work as well as mobile app development. All of it sits in one prioritised backlog and is delivered within your plan’s capacity, one active workstream at a time. Priorities can change; additional parallel workstreams require more capacity.
Product and UI/UX design, native iOS and Android engineering, React Native or Flutter engineering, QA and testing, DevOps and release pipelines, App Store and Google Play submission, one accountable delivery owner, and maintenance after launch. Every plan includes $500 in AI infrastructure catalog credits in your first month. Annual plans also include $10,000 in specialist services: a technical assessment, a delivery roadmap and CI/CD pipeline setup.
You rank the backlog. Your delivery owner scopes the top request, agrees acceptance criteria with you, and the team delivers it. You can reorder anything that has not started. One request is active at a time on Core; additional parallel workstreams require more capacity.
Yes. You can queue as many requests as you like on your plan backlog. They are delivered in your priority order, one active workstream at a time, so a longer queue takes more months rather than running in parallel.
The clock starts when you confirm scope and give access to your repositories, store accounts and CI. Within 48 hours the team has its first code in production in your environment. Within 14 days your first agreed deliverable ships, for example a working feature build on TestFlight or the Google Play internal track. If it does not, your first month is free.
48 hours to first code in production means the first change merged and deployed through your pipeline, counted from the day scope and access are confirmed. 14 days means the deliverable named at kickoff ships within 14 days of that date, or your first month is free. “Thousands of companies” counts organisations that have bought engineering services from Scrums.com since 2012. 98%+ first-time App Store approval is the share of iOS submissions made by Scrums.com teams that Apple approved on first review. 40-60% cost savings is the figure the current Scrums.com mobile app page states for delivery cost against US and UK firms; it is not a quote for your scope.
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. We work in two-week sprints so you see working builds continuously.
Native development uses Swift and SwiftUI for iOS and Kotlin and Jetpack Compose for Android. It gives the best performance and the latest platform features, but needs two codebases. React Native or Flutter use a single codebase for both platforms, with faster time to market and lower cost for most B2B and SaaS applications.
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. Cross-platform development with React Native or Flutter lets you launch on both platforms at the same time.
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.
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.
The same plan covers mobile app maintenance: crash monitoring and bug fixes, OS compatibility updates when Apple and Google ship new versions, security patches and dependency updates, and staged rollouts. Maintenance and new features share your workstream, and you set the split.
Stop hiring for mobile. Start shipping apps.
