How much does it cost to build an app? What really drives the price

Last reviewed 3 November 2026

Search this and you’ll find price ranges so wide they tell you very little. The same app idea can reasonably cost very different amounts depending on a few decisions. Those decisions are the useful part, so that’s what this guide covers.

Short answer

It depends mostly on how many features the first version has, how many platforms it runs on, what it connects to, and who builds it. To get a real number, describe the first version clearly and ask for a fixed quote that lists what’s included. Plan for running costs after launch as well.

Why we don’t quote a figure here

A booking app could mean one simple calendar, or payments, staff schedules, reminders and an admin dashboard. Both get called “a booking app”, and they’re very different projects. Any number on this page would be a guess about your project, so here’s how to work out a real one.

What moves the price most

Number of features. The biggest factor. Each one needs design, building, testing and fixing.
User accounts and types of user. An app with customers, staff and admins is close to three products.
iPhone, Android, web, or all three. Cross-platform tools such as Flutter and React Native can share much of the work, though not all of it.
Connections to other systems: payments, maps, calendars, or your existing software. Older systems take longer.
Real-time features: chat, live tracking, video.
AI features, including testing that the answers are reliable, and the ongoing usage bills.
Admin tools. Someone has to manage the content, users and refunds, and that’s usually a separate dashboard.
Regulated data: health, finance and children’s data bring extra security and legal work.
Design: custom screens and animation cost more than proven, standard patterns.
Who builds it: experience and location both change the rate, and an inexperienced team can cost more once fixes are counted.

How to spend less without regretting it

Cut the first version hard. List every feature, then ask of each one: would anyone refuse to use the app without it? See how to build an MVP.
Test before you build. A clickable prototype shows you what people understand, for a fraction of the cost of building it.
Start on one platform if your customers are mostly on one, or use cross-platform from the start.
Use existing services for sign-in, payments and email, so nobody builds them from scratch.
Don’t cut testing and security. Those savings come back as much bigger bills.

What you’ll pay after launch

People often forget these when they plan a budget:

Store fees. The Apple Developer Program is 99 USD per membership year, though prices can vary by region. Google Play has a one-time 25 USD registration fee. Both stores also take a commission on many digital sales.
Hosting, database and storage, which usually grow with your users.
Paid services: email, text messages, maps, payment fees and AI usage.
Maintenance. New iOS and Android versions, security updates and bug fixes never stop. See our guide to app maintenance costs.
Improvements as you learn from real customers. For many products this becomes the largest cost, and the most useful.

What about building it with AI tools?

Tools like Lovable, Bolt, Replit and Base44 can get a working version in front of people for a small subscription, and that’s a great way to test an idea. Budget for what comes next if it takes off: credits or usage charges, and professional work on security, data and stability. Our security checklist shows what to check.

How to get a quote you can trust

Describe the first version in writing and send the same document to everyone.
Ask for a fixed quote and a list of what’s included: design, backend, testing, store submission and post-launch fixes.
Ask what’s excluded, and how changes get priced.
Tie payments to working milestones. See what to put in the contract.
Be careful of a very low quote with little detail. The difference often reappears later as change requests or an unfinished app.

Questions founders ask

Why do app cost estimates vary so much?

Because the word “app” covers everything from a simple tool to a whole platform. Teams also assume different scopes, so check what each quote includes before you compare the totals.

How much does it cost to keep an app on the App Store and Google Play?

Apple’s program is an annual fee and Google’s registration is a one-time fee, as above. The real running costs are usually hosting, third-party services and maintenance. If an Apple membership lapses, your apps stop being available until you renew it.

Can I get a fixed price?

Often, yes, once the first version is clearly defined. We give fixed quotes after a free call. If anyone gives you a firm price before they understand the app, ask what they’ve assumed.
