WhatsAppMobile app development cost: the short answer
Building a professional mobile app typically costs $30,000 to $150,000 for a first release on iOS and Android, including design, backend and launch. Simple apps can cost less; complex apps such as marketplaces, fintech or telehealth often exceed $150,000. Ongoing costs for hosting, updates and maintenance continue after launch.
Cost by app type
| App type | Examples | Typical timeline | Typical cost (USD) |
|---|---|---|---|
| Simple app | Content, catalogue, simple utility | 6–10 weeks | $20k – $45k |
| App with accounts & payments | Booking, ordering, membership | 12–18 weeks | $50k – $110k |
| Social or real-time app | Chat, community, live tracking | 4–7 months | $90k – $180k |
| Marketplace / on-demand | Two-sided platforms with payments | 4–8 months | $100k – $250k |
| Regulated app | Fintech, telehealth | 5–9 months | $120k – $300k |
Typical ranges for apps on both iOS and Android, built by experienced teams. Your estimate depends on scope and team location.
Where the money goes
| Phase | Share of budget | What it covers |
|---|---|---|
| Discovery & UX/UI design | 10–15% | Research, user flows, prototype and visual design |
| App development | 35–45% | Screens, logic, offline support, device features |
| Backend & admin panel | 20–30% | APIs, database, admin tools, integrations |
| QA & testing | 10–15% | Testing on real devices, automation, store-readiness |
| Launch & project management | 5–10% | Store submission, coordination, reporting |
Many first-time app budgets forget the backend and admin panel — often a third of the work.
Native vs cross-platform cost
Building separate native apps for iOS (Swift) and Android (Kotlin) means two codebases. Cross-platform frameworks such as Flutter and React Native use one codebase for both, typically saving 25–40% on build cost and more on maintenance. Native is still worth it for apps that depend on advanced device features or demanding performance. See cross-platform app development for a full comparison.
Features that add cost
| Feature | Effect on cost |
|---|---|
| User accounts & social login | Low |
| Push notifications | Low |
| In-app payments / subscriptions | Medium |
| Maps & geolocation | Medium |
| Chat & real-time updates | Medium–high |
| Offline mode with sync | Medium–high |
| Video calls or streaming | High |
| AI features | Medium–high, plus usage costs |
| Integration with legacy systems | Varies widely |
Ongoing costs after launch
- Developer accounts — Apple Developer Program ($99/year) and Google Play (one-time $25).
- Store commission — Apple and Google take a commission (commonly 15–30%) on digital goods and subscriptions sold in-app.
- Hosting & services — backend hosting, push notifications, maps, SMS and analytics.
- Maintenance — yearly OS updates, SDK upgrades and bug fixes, commonly 15–20% of the build cost per year.
- New features — based on reviews and usage data.
How to reduce the cost of your app
- Launch an MVP with one core user journey
- Choose cross-platform unless native is truly needed
- Use managed services such as Firebase or Supabase for authentication and data
- Start with a web admin panel built on proven tools
- Test the prototype with users before development to avoid rework
- Plan phases so revenue or funding can fund later features
Worked example: a booking app for iOS and Android
Consider a fitness studio that wants an app where members book classes, buy class packs and receive reminders. The app needs sign-up and login, a class schedule, booking and cancellation, in-app purchase of passes, push notifications and a profile. Behind it, the studio needs an admin panel to manage classes, instructors and members, plus integration with its payment provider.
Built cross-platform with Flutter or React Native, the mobile app itself might take around 8–10 weeks of development; the backend and admin panel another 5–6 weeks running partly in parallel; design, testing and launch add to the total. A typical team delivers this in around four months for roughly $60,000–$100,000, depending on rates. Building two separate native apps would usually add a significant share to the mobile portion of the budget, while launching on one platform first or using a ready-made booking backend could reduce it.
Questions to ask before you budget
- Who are the users, and which platform do they use most?
- What is the single most important action users must be able to complete?
- Do you need an admin panel, and who will use it?
- Which existing systems must the app connect to?
- How will the app make money — subscriptions, purchases, or by supporting another business?
- Who will maintain the app after launch?
App store, platform and compliance costs
Some costs are fixed by the platforms, whoever builds the app. They are small next to development but easy to forget.
| Item | What it is | Notes |
|---|---|---|
| Apple Developer Program | Annual membership needed to publish on the App Store | Annual fee set by Apple |
| Google Play developer account | One-time registration to publish on Google Play | One-time fee set by Google |
| Store commissions | Share of in-app purchases and subscriptions | Rates vary by programme and revenue level — check current Apple and Google terms |
| Test devices | A small set of real phones and tablets | Complemented by cloud device farms |
| Privacy & store review | Privacy labels, data-safety forms, review guideline compliance | Time, not money — but rejections delay launch |
Check current fees and commission rates with Apple and Google before you finalise a business model; both change their programmes from time to time.
The back end: the cost people forget
Most apps are only the visible part of a system. Behind them sit user accounts, a database, an API, an admin panel, push notifications and integrations. For many business apps the back end and admin tools take as much effort as the app screens.
| Back-end option | Best for | Trade-off |
|---|---|---|
| Backend-as-a-service (Firebase, Supabase) | MVPs, simple data, fast launch | Less flexibility for complex logic; costs scale with usage |
| Custom API (Node.js, Laravel, .NET) | Business rules, integrations, long-term products | More build effort, full control |
| Existing system API | Apps on top of your CRM, ERP or platform | Depends on the quality of the existing API |
Scenario: same app, three budgets
Take an illustrative service-booking app and three ways to scope it. The point is not the exact figures but how scope decisions move cost.
| Scope | What is included | Relative cost |
|---|---|---|
| Lean MVP | One platform via cross-platform framework, core booking flow, card payments, basic admin | Lowest |
| Market launch | iOS and Android, accounts, booking, payments, reviews, push notifications, analytics, admin dashboard | Roughly 2–3× the lean MVP |
| Scaled product | All of the above plus multi-location, staff app, offline mode, integrations, advanced reporting | Roughly 4–6× the lean MVP |
Illustrative multiples, not quotes. Actual costs depend on design, integrations and team.
Many successful apps start at the first row, prove demand and grow into the third. Funding the second or third row before anyone has used the product is the most common way to overspend.
Cost-saving decisions that don’t hurt quality
- Use a cross-platform framework unless you truly need native-only features
- Start with a design system or proven UI kit instead of fully bespoke visuals
- Use managed services for authentication, payments, push and email
- Launch with one user type and add roles later
- Release a web admin panel before building admin features into the app
- Automate tests for the core flow so later changes cost less
Each of these trims weeks without weakening the product. See MVP development for how we scope first releases.
Planning year-two costs
Year two of an app usually looks like this: annual iOS and Android updates to stay compatible with new OS versions, dependency and security updates, bug fixes, hosting that grows with users, and a steady stream of improvements. A common rule of thumb is to budget 15–20% of the initial build cost each year for maintenance, plus a separate budget for new features.
Design depth and its effect on cost
| Design approach | Description | Effect on budget |
|---|---|---|
| Platform-standard UI | Native iOS and Material components with your brand colours | Lowest design and build effort |
| Custom branded UI | Bespoke screens, icons and illustrations | Moderate increase |
| Motion-rich experience | Custom animations, transitions and micro-interactions | Significant increase in design and development |
Platform-standard interfaces also feel familiar to users and age better as iOS and Android evolve.
Checklist before requesting quotes
- A one-paragraph description of the app and its users
- The three to five core user journeys
- Platforms: iOS, Android, tablet, web admin
- Integrations with existing systems
- How the app makes money, if it does
- Target launch date and any fixed events
- A budget range
Sending the same brief to every vendor makes quotes far easier to compare.
Who should be on a mobile app team
| Role | Why you need it |
|---|---|
| Product owner (you or your delegate) | Makes priority decisions and accepts finished work |
| UI/UX designer | Turns journeys into screens users understand |
| Mobile developer(s) | Build the app; one cross-platform developer can cover both stores |
| Back-end developer | APIs, data, admin panel, integrations |
| QA engineer | Tests on real devices and OS versions |
| Project lead | Plans sprints, manages risk and communication |
Small apps combine roles; larger ones add specialists. A quote that leaves out testing or back-end work will cost more later, not less.
Cost of updating an existing app versus rebuilding
If you already have an app that is slow, outdated or hard to change, the first question is whether to improve it or start again. Rebuilding feels clean but repeats work that already exists; updating is cheaper only if the codebase is in reasonable health.
| Situation | Usually cheaper option |
|---|---|
| Code is on a supported framework version with some tests | Incremental update and refactor |
| Framework or language is years out of date and unsupported | Rebuild, reusing the back end where possible |
| Design is dated but logic is sound | Redesign the interface on the existing code |
| Back end is the main problem | Keep the apps, rebuild or modernise the API |
Rules of thumb only — a short code audit is the reliable way to decide.
A code audit typically takes one to two weeks and gives you a clear recommendation with an estimate for each option, which is far cheaper than discovering halfway through an update that a rebuild was needed.
Mini FAQ: costs that surprise first-time app owners
- Do app store fees apply to my in-app purchases? Digital goods sold inside iOS and Android apps are generally subject to the stores’ commission rules; physical goods and services usually are not. Check current store policies for your model.
- Do I pay again when Apple or Google release a new OS? Usually some work is needed each year to stay compatible; budget for it in maintenance.
- Is a web admin panel included? Not always. Most apps need one for content, users and support, and it should be in the estimate explicitly.
