An app is software that runs on a phone or tablet, either installed from an app store or opened in a browser. Pew Research's 2026 mobile fact sheet finds 91% of US adults own a smartphone, which is why the question comes up so often and why the platform decision matters.
This article is part of our technology guides. The wider question of what any custom software costs, and the three pricing models, is in how much does custom software cost.
What do published sources say an app costs to build?
The largest public dataset is Clutch, which collects pricing from verified client reviews of app development companies. Its resource on the cost to build a mobile app, updated 21 September 2026, says the average cost of app development projects is $90,780.11, the timeline is about 11 months, and hourly rates are $25 to $49 for most listed firms. Treat the average as a ceiling for comparison; it is no typical price: a few large projects pull it up, and a simple app with a handful of screens costs far less.
Where the team sits changes the hourly rate more than anything else. Clutch's software developers pricing page, updated the same day, lists average hourly cost by country: $50 to $99 in the USA, $100 to $149 in Canada and Australia, $50 to $99 in Poland and Spain, and $25 to $49 in India, the Philippines, Ukraine and Mexico. For building in-house, the US Bureau of Labor Statistics puts the median pay of software developers at $134,040 a year in 2025. The table below sets the figures out. They are market estimates, not our prices.
Why do app quotes vary so much?
Because an app is hours multiplied by rate, and the hours depend on decisions that are often not made when the quote is requested. Two vendors asked for "a booking app" will assume different platforms, features, integrations and design depth. The drivers below explain most of the spread.
What moves the cost of building an app
In rough order of effect:
- Platforms. iOS only, Android only, both, or web. Each native platform is its own build and its own maintenance.
- Features in version one. Sign-in, payments, maps, chat, notifications, offline use, camera, file upload: each is a block of design, build and test. Most first feature lists are twice as long as they need to be.
- Integrations. Connecting to a CRM, an ERP, a payment provider, a booking system or a legacy database adds work in proportion to how well documented the other side is.
- Design depth. A tool for trained staff needs clarity; a consumer app needs research, prototypes, testing and polish.
- The back end. Most apps need a server, a database, user accounts and an admin panel. This is often half the project and is the part first-time buyers forget to count.
- Security and compliance. Payments, health data and personal data under GDPR, CCPA or PIPEDA add encryption, access control and documentation.
- Who builds it, and where. The Clutch country table above: the same scope can cost two to three times more depending on the team's location.
Native, cross-platform or web app: three cost structures
A native app is written separately for iOS and Android, which gives the best access to device features and performance, and roughly doubles build and maintenance for two platforms. A cross-platform app shares most of one codebase across both stores, which lowers cost and keeps store distribution, with some trade-offs on the most device-specific features.
A progressive web app runs in the browser and can be installed to the home screen. Google's web.dev explains that PWAs are web apps "built and enhanced with modern APIs" that can reach any web user on any device with a single codebase, and that they can be installed to run in a standalone window, while noting that some capabilities are still out of the web's reach. For many business tools a web app is the lowest-cost route and avoids the app stores entirely; for apps that need deep device access or store presence, native or cross-platform wins. Our sibling guide on web apps against mobile apps covers the choice in detail once it is published.
What a complete app quote includes
A quote that says only "app development" hides most of the work. Expect: discovery (users, flows, success measures), design (wireframes, visual design, prototype testing), front-end build per platform, back-end and database, integrations, testing on real devices, store submission and release, and documentation. After launch: hosting, monitoring, operating system and store updates, bug fixes and new features, which most companies budget as a share of the build cost each year. Ask for each as its own line.
Building an app with AI tools: does it change the cost?
Many people now add "with AI" to the question. Two things are true at once. AI-assisted coding, design and testing tools can shorten parts of the build, especially boilerplate, documentation and test writing, and a team using them well should quote fewer hours for the same scope. They do not remove the work that decides cost: understanding users, choosing features, designing flows, integrating real systems, securing data and testing on devices. Ask a vendor where AI shortens its work and where a named person still reviews everything; the honest answer is specific.
How to get an app quote you can compare
Six steps:
- Write one page: who uses the app, the ten things it must do in version one, the systems it connects to, and the platforms it must run on.
- Send the same page to each vendor and ask for the scope back as deliverables, each with a fee or an hour estimate.
- Ask which platform approach they recommend and why, and what the cost difference would be.
- Ask what is excluded: back end, hosting, store accounts, third-party services, design revisions, post-launch support.
- Ask who will build it, where they sit, and how you will see progress week to week.
- Compare line by line. A lower total that leaves out the back end is not lower.
How to keep app development cost down
Ship the smallest version that solves the real problem and learn from use before adding features. Choose one platform first if your users allow it, or a cross-platform or web approach if they do not. Use managed services for sign-in, payments and notifications rather than building them. Reuse existing systems through integration instead of rebuilding them. Keep one decision-maker on your side who answers the same day. And budget for after launch from the start, so the first store update is not a surprise. For a product that will keep growing, a retained team can cost less than repeated projects; our dedicated developers page explains that model.
Conclusion
An app costs what its scope takes to build by the team you choose. The published checkpoints are Clutch's $90,780 average and 11-month timeline, its $25 to $49 typical rate and its country table from $25 to $149 an hour (all 21 September 2026), and the BLS median of $134,040 a year for a US developer in 2025. Decide the platforms and the first version before you ask for quotes, then compare them line by line.
