How much does it cost to build an app in 2026? Prices by route

In 2026 a custom mobile app costs roughly US$20,000 to $150,000 or more from an agency, US$5,000 to $40,000 from a freelancer billing $30 to $150 an hour, a monthly subscription plus weeks of your own time with a no-code tool, and from free to $11.01 a month with an AI app builder such as App Builder Agent. On top of the build itself, budget Google Play's one-time $25 registration, Apple's $99 a year if you want an iPhone version, and a small monthly amount for hosting. UK and EU prices track the US closely once converted.

The honest answer to "how much does an app cost" is that it depends far more on who builds it than on what it does. The same salon booking app can be a $40,000 agency project, a $9,000 freelancer job, a $50-a-month no-code subscription that eats your evenings for two months, or an afternoon with an AI agent and a $1.49 plan. This guide puts real ranges next to each route so you can pick one with your eyes open, then walks through two worked examples with the arithmetic shown.

What you are actually paying for

Every route has the same ingredients; they are just priced differently. Understanding them makes the ranges below less mysterious.

• Design - screens, colours, icon, the flow between screens. Agencies bill this as a separate phase; AI builders generate a first version from your description and you adjust it by describing changes.
• Frontend code - the app people tap. This is where most of the hours go with a freelancer or agency.
• Backend - accounts, a database, file storage, notifications. Custom backends are expensive to write and to keep running; hosted backends are cheap but tie you to a provider.
• Builds and store setup - signing keys, package ids, bundles, screenshots, the Play Console forms. Tedious rather than expensive, unless someone bills you by the hour for it.
• Maintenance - Android and iOS change every year. Agencies commonly quote 15 to 20 percent of the build cost per year to keep an app current.

Cost by route: US, UK and EU

Ranges below are for a small-to-medium consumer or business app (login, a handful of screens, a database) and reflect publicly listed rates and common quotes as of 2026. Complex apps with video, payments, maps and real-time features sit at the top of each range or above it.

A note on regions: London agency rates are close to US coastal rates; Manchester, Leeds and Glasgow are lower. In the EU, Berlin, Amsterdam and Paris agencies sit near UK prices, while Portugal, Poland and the Baltics are often 30 to 50 percent lower for equivalent work. Tool subscriptions, including the App Builder Agent plans, are priced in US dollars and do not change by country, though VAT may be added in the UK and EU.

The hidden costs nobody quotes

These are the line items that surprise people after the build is "done". None of them is large, but together they matter for a small budget.

• Google Play developer account - a one-time US$25 fee, plus identity verification, as of 2026. Personal accounts also have to run a closed test with 12 testers for 14 days before a public release, which costs time rather than money. The Google Play publishing guide covers the whole process.
• Apple Developer Program - US$99 per year, and you need a Mac or a cloud Mac service to build for iOS. If your customers are mostly on Android, or a website version is enough for iPhone users, you can skip this entirely at first.
• Hosting and backend - a custom backend on a cloud provider typically runs $1.49 to $50 a month for a small app, more with traffic. App Builder Agent's hosted backend runs on the platform's servers and is included with your plan.
• Maintenance - Android raises its target API requirement every year, and libraries change. With an agency this is a retainer; with an AI builder it is usually one prompt and a rebuild.
• Design assets - an icon, a feature graphic and screenshots. Free if you make them from the preview; $50 to $500 if you hire someone on a freelance marketplace.
• Third-party APIs - maps, SMS, payments and AI models all bill per use. Small apps usually stay in free tiers; check the tier limits before you promise a feature.
• Your own time - the real cost of no-code and DIY routes. Two months of evenings is not free, even if no invoice arrives.

Worked example: a salon booking app

Scope: customers see services and prices, pick a stylist and a time slot, get a confirmation, and can cancel. The owner gets a simple dashboard of the day's bookings. Android first, website for everyone else.

• Agency (US) - typical quote $35,000 to $60,000 including design, iOS and Android, and a custom backend. Add $6,000 to $10,000 a year for maintenance. Timeline four to five months.
• Freelancer (UK) - around 120 hours at £60 an hour is £7,200, plus a hosted backend at about £10 a month. Timeline six to ten weeks, depending on availability.
• No-code tool - a plan at roughly $30 to $60 a month, and perhaps 40 to 80 hours of your time learning the tool and wiring the booking logic. Publishing an Android build is possible on most tools' paid tiers.
• App Builder Agent - the first version fits within the free plan's 500K tokens; unlimited builds are $1.49 on the Member plan. A Member plan at $1.49 per 30 days gives unlimited builds and source export; a Pro plan at $5.72 covers heavier iteration. Google's $25 fee to publish. Total cash cost for a v1: $26 to $35.

The prompt that starts the App Builder Agent version is a paragraph, not a specification document:

If booking logic is what you need, the booking and appointment app guide goes deeper on slots, reminders and no-shows.

Worked example: a loyalty app

Scope: a coffee shop punch card. Customers collect a stamp per purchase (the barista taps a code or scans a QR), the tenth coffee is free, and the owner can see how many stamps and rewards were issued this month.

• Agency (EU) - typically €20,000 to €35,000. Loyalty apps are simple, but agencies still price design, two platforms and a backend. Many small shops are quoted this and decide against an app at all.
• Freelancer (US) - 60 to 90 hours at $80 an hour is $4,800 to $7,200. A good freelancer will suggest a QR code flow to avoid building point-of-sale integration.
• No-code tool - a monthly plan and a weekend or two. Stamp logic is easy in most tools; the owner dashboard and staff PIN take longer.
• App Builder Agent - well within the free plan. If you later want the customer-facing app on Google Play and the staff app as a separate APK, the $1.49 Member plan removes the build cap. The coffee shop loyalty guide has the full prompt and the anti-fraud details.

How to keep the bill small whichever route you take

1. Build Android first, add iPhone later. Android is cheaper to build for and to publish on, and a website version covers iPhone users in the meantime.
2. Use a hosted backend rather than paying for a custom one until you have real traffic that demands it.
3. Ship a small v1 with three screens that work rather than ten that half work. Every extra screen costs money on paid routes and tokens on AI routes.
4. Own the code. If you use a tool, make sure you can export the source. App Builder Agent includes source export on the Member plan and above; with agencies, put code ownership in the contract.
5. Start free. A free plan tells you within an hour whether the AI route can deliver your app, before you spend anything. The free plan guide lists exactly what is included.

Apps with accounts and an admin view are the most common thing people price up; browse the login and dashboard apps in the gallery to see what a finished one looks like, then describe yours in the builder and compare the result with the quotes you have been given.
