How much does it cost to build an app?
Building a mobile app in the US typically costs roughly $25,000 to $75,000 for a simple app, $75,000 to $200,000 for a mid-size app with accounts, payments and a backend, and more for complex apps. Building one cross-platform app instead of separate iOS and Android apps usually brings the cost down. Zoti builds custom mobile apps on monthly plans starting at $499/month, instead of one large upfront fee.

How much does it cost to build an app, by size
These ranges are rough and typical for professionally built apps in the US. Real quotes swing widely with scope, team location and how polished the app needs to be.
- Simple app, roughly $25,000 to $75,000: a few screens, basic sign-in, content or forms, and a light backend. Examples are a booking app for one location, an internal checklist app for field staff, or a companion app to an existing website.
- Mid-size app, roughly $75,000 to $200,000: user accounts, payments or subscriptions, push notifications, an admin panel, and integrations with your other systems.
- Complex app, $200,000 or more: marketplaces with two sides, real-time chat or tracking, offline sync, video, heavy security needs, or several connected apps (customer, driver, admin).
iOS, Android or cross-platform
This is the first big decision that moves the price. There are three common routes:
- iOS only: one app built natively for iPhone. A sensible start if your users are mostly on iPhone, but you will need Android later for most consumer audiences.
- Android only: the mirror image. Common when your users are field staff on company-issued Android devices.
- Separate native apps: two codebases, one per platform. The best fit for apps that lean hard on device features or need top performance, and close to double the build and upkeep.
- Cross-platform: one codebase that runs on both, using frameworks such as React Native or Flutter. For most business apps this gives near-native results at a lower cost than two native apps, which is why it is the default for many projects.
The backend is often half the work
The part you tap on your phone is only the front of an app. Behind it sits a backend: the database, user accounts, business logic, an API the app talks to, and usually an admin panel where your staff manage content, users and orders. Payments, notifications, file uploads and integrations with your other software all live here too.
Quotes that look surprisingly low often leave the backend vague. Ask exactly what is included: who builds the admin panel, where data is stored, how users reset passwords, and how the app will connect to your existing tools.
Costs beyond the build
- App store accounts: Apple charges a yearly fee for its developer program and Google charges a one-time registration fee. Both take a commission on many in-app sales of digital goods and subscriptions, so factor that into pricing if you sell inside the app.
- App store review: every release is reviewed by Apple and Google. Rejections mean fixes and resubmission, which is time someone has to pay for.
- OS updates: new iOS and Android versions arrive every year, and apps need testing and updates to keep working and stay listed.
- Hosting for the backend, which grows with your user count.
- Third-party services: push notifications, maps, SMS, analytics, crash reporting and payment processing typically bill per use or monthly.
- Ongoing changes: user feedback after launch always produces a list of improvements.
How to get an accurate app quote
- Describe the core actionWrite down the one thing users must be able to do in the app. Everything else is secondary.
- Decide on platformsSay whether you need iOS, Android or both, and whether cross-platform is acceptable.
- Sketch the main screensRough boxes on paper are enough. Count them and note what each one does.
- Spell out the backendWho manages the app behind the scenes, what they need to see, and what systems it must connect to.
- Ask for the same scope from everyoneSend vendors the same brief so the quotes are comparable, and ask what is excluded.
- Ask about year twoGet hosting, app store upkeep and change costs in writing, not just the launch price.
Large upfront fee or monthly plan
Most agencies quote apps as a single project fee, paid in stages, with updates and hosting billed separately once the app is live. That can leave you with a finished app and no budget for the fixes and OS updates every app needs. Zoti offers a monthly model instead: custom projects start at $499/month, covering design, development, hosting and ongoing changes, with a written quote before work begins. Zoti also does one-off projects with a deposit and milestones if a single fee suits you better. Either way, compare the total over two or three years rather than the launch price alone.

Common questions
How much does a simple app cost?
A simple app with a few screens, basic sign-in and a light backend often lands somewhere around $25,000 to $75,000 when built by a US agency. Very basic apps can cost less, and prices vary widely by team and scope.
Is it cheaper to build one app for iOS and Android?
Usually, yes. A cross-platform app shares one codebase across both platforms, so you build and maintain most features once. Separate native apps make sense when the app relies heavily on device features or needs maximum performance.
How much does custom app development cost per year after launch?
Plan for backend hosting, app store developer fees, third-party services, updates for new iOS and Android versions, and new features. The total depends on your user count and how often the app changes, so ask for these costs in writing before you sign.
Do Apple and Google take a cut of app revenue?
Both stores take a commission on many in-app purchases and subscriptions for digital goods. Sales of physical goods and real-world services are generally handled differently. Check each store’s current rules for your situation, since they change.
Can I build an app with no-code tools instead?
For a prototype or a simple internal app, no-code app builders can work and cost less upfront. They become limiting once you need custom logic, integrations or a polished customer experience, and you may have to rebuild later.
