How Much Does It Cost to Build an App?

What mobile app development costs on average

Mobile app development costs $90,780 on average, according to Clutch's pricing data for mobile app developers. The same page lists $10,000 to $49,999 as the most common project band, an average monthly spend of $8,188 and a typical project length of about 11 months.

That average describes a real product with a backend, user accounts and a few rounds of updates after launch. A first version with a narrow feature set usually costs far less. A marketplace, a fintech app or anything with live video or offline sync usually costs more.

Clutch also lists a typical mobile rate of $25 to $49 an hour across all firms. Rates vary widely by country, which the rate section below covers. The price of your app comes down to three things: what it must do on day one, which platforms it runs on and who builds it.

App cost bands by build approach

The way you build an app sets its price band before any feature is counted. The table below collects published ranges for each approach. These are industry figures from the named sources, not Arcesso prices.

Lower bands buy speed and a test of demand. Higher bands buy tested code, security work, app store releases and a team that stays accountable after launch.

iOS vs Android vs cross-platform app cost

A cross-platform app usually costs less than building separate native iOS and Android apps. With React Native or Flutter, one team writes most of the code once and ships it to both stores. With native apps, you fund two codebases written in Swift and Kotlin, two sets of tests and two release cycles.

Native still wins in some cases: heavy use of device hardware, advanced graphics, or features that depend on the newest platform APIs on launch day. For most business apps, booking tools, marketplaces and dashboards, cross-platform is the sensible default.

AI-assisted app builds: what they cost and what they skip

AI-assisted app builds cost far less upfront, and they are changing how founders start. Tools such as Lovable, Bolt and Claude Code can produce a working prototype in days. Interest is large: vibecoding.app, using DataForSEO data, reports about 110,000 US searches a month for "vibe coding", and Fiverr reported searches for Claude Code specialists up 938% between late 2025 and early 2026.

The catch is what a prototype skips. Generated apps often lack secure authentication, data access rules, automated tests, backups, error tracking and the review steps Apple and Google require for store release. Those gaps are fine for a demo and costly in production.

A sensible path is to prototype with AI tools, test demand, then pay engineers to harden or rebuild the parts that handle money, personal data and scale. That keeps early spend low without shipping risk to real users.

What moves the price of an app

Backend work and integrations move the price of an app more than screen count. Users see the screens, but most of the budget goes to the systems behind them.

• User accounts and roles: sign-up, login, password reset and admin tools add a full backend.
• Payments: in-app purchases, Stripe checkout or payouts add rules, testing and store review time.
• Real-time features: chat, live tracking and notifications need extra infrastructure.
• Offline mode: syncing data when the phone reconnects is one of the hardest parts of mobile work.
• Integrations: CRMs, booking systems, maps and health data each add work and testing.
• AI features: chat assistants, image recognition or voice add model costs and evaluation work.
• Design: custom animation and brand-heavy design cost more than a standard component library.
• Compliance: health or financial data adds access controls, audit logs and legal review.

Ongoing app costs after launch

An app keeps costing money after launch, and the bill grows with your users. Plan for the developer account fees Apple and Google set for store publishing, backend hosting, push notifications, analytics, error tracking and any paid APIs such as maps or AI models.

Maintenance is the line people forget. Apple and Google ship major OS updates every year, and apps need testing and fixes to keep working and to stay in the stores. Libraries need security updates. Users ask for new features.

Ask each vendor for a written estimate of monthly running costs and a support option before you sign. Make sure the app store accounts, the code repository and the hosting accounts are in your company's name, not the vendor's.

Mobile developer hourly rates by region

Mobile developer rates differ more by country than by skill level. Clutch's mobile pricing data lists typical rates of $50 to $99 an hour in Canada and Poland, $25 to $49 in Mexico and the Philippines, under $25 in India and $100 to $149 in Australia. Clutch lists US mobile firms at $25 to $49, lower than its US software band of $50 to $99, which shows how coarse these bands are.

Use the bands for rough comparison only. A team at a lower rate that needs more hours, more rework or more of your time can cost more in total than a team at a higher rate that ships on the first pass.

The better comparison is total price for a defined first release, with testing, store submission and handover included in writing.

How to budget and scope your first app release

The best way to budget an app is to cut the first release to the one job users need most. List every feature, then mark each one must-have for launch, later or nice to have. Most first releases ship with a short list and learn the rest from real users.

Decide on platforms early. If your users split between iPhone and Android, plan for cross-platform. If they are mostly on one, consider launching there first.

Arcesso builds mobile apps in React Native and Flutter with Next.js, Node, Python and Supabase or AWS behind them. Discovery is fixed price and credited in full to the build, you own 100% of the code and IP from the first commit, and kickoff happens within 14 days of signing.

When you should not build a custom app

You should not build a custom app when a mobile-friendly website does the job. If users visit rarely, do not need push notifications and do not use device features, a responsive web app is cheaper to build and has no store review.

Skip custom work too if you have not tested demand. A no-code tool or an AI-assisted prototype can answer that question for a fraction of an agency budget.

We will tell you if we are not the right fit. If your budget is in the freelancer band and you need a quick demo for investors, a prototype tool is the better spend. Come back when you need it to run in production.
