How Much Does It Cost to Build an App? The Drivers

"How much does it cost to build an app?" is one of the most common questions we get, and any honest answer starts with "it depends on what the app does." That is not a dodge. Two apps that look similar on the home screen can be very different projects, because one shows a list of information and the other takes payments, works offline and syncs with your business systems.

So instead of a number, this guide gives you the cost drivers, the platform fees and rules that are fixed, and a way to scope a first version so you can get comparable quotes.

What it costs to build an app before any code: the fixed fees

A few costs are the same for everyone and published by the platforms:

• Apple Developer Program: Apple says it is "99 USD per membership year," with prices that may vary by region. You need it to publish on the App Store. Nonprofits, accredited educational institutions and government entities can request a fee waiver.
• Google Play developer account: Google lists "a US$25 one-time registration fee."

Those are small. The real cost is in the design, development and upkeep that follow.

Cost driver 1: which platforms

• iOS only or Android only. One codebase, one set of devices to test.
• Both, built natively. Two codebases, usually two specialists, and two sets of work for every new feature and fix.
• Both, with a cross-platform framework. One shared codebase for most screens, with native work where a feature needs it. This is a common choice for business apps.
• A web app instead. If your users do not need the app stores, a web app can be cheaper to build and update. Our post on web app costs covers that route.

Decide this from who your users are and how they will find you, not from preference.

Cost driver 2: the features

Features move the price more than anything else. These are the ones that add the most work:

• Accounts and sign-in. Login, password reset and profiles. Apple's App Store Review Guidelines also say: "If your app supports account creation, you must also offer account deletion within the app." Budget for it from the start.
• Payments. Apple's guidelines say physical goods and services consumed outside the app must use payment methods other than in-app purchase, such as Apple Pay or card entry. Digital goods are different: guideline 3.1.1 requires Apple's in-app purchase for paid features and content inside the app, such as subscriptions and premium content, with exceptions that vary by storefront. Read the current guideline before you design the payment flow, because getting this wrong means rejection and rework.
• Offline use and sync. Letting a caregiver log a visit without signal, then syncing later, is one of the most complex features to get right.
• Real-time features. Chat, live tracking and live updates need servers that keep connections open.
• Integrations. Connecting to your CRM, scheduling system, accounting software or EVV platform. Each integration has its own documentation, limits and testing.
• Notifications. Simple reminders are easy; personalized notifications driven by user behavior take more work.
• AI features. A chat assistant or document reader adds model costs and testing for wrong answers.

Cost driver 3: everything behind the app

The screens are the visible part. Behind them, most business apps need:

• A backend: database, APIs and file storage.
• An admin panel where your team manages users, content and orders. This is often forgotten in early quotes and can be a project of its own.
• Security and privacy work, especially if the app handles health, financial or children's data.
• Analytics so you know what people use.

Cost driver 4: design and testing

Good app design covers every state: empty screens, loading, errors, no signal, first-time use. Each one is a screen someone has to design and build. Testing then covers a range of devices and screen sizes on both platforms.

The stores add their own gates. Apple's guideline 4.2, Minimum Functionality, expects an app to offer more than "a repackaged website," so a thin wrapper around your site may be rejected. On Google Play, Google says developers with personal accounts created after November 13, 2023 "must run a closed test for their app with a minimum of 12 testers who have been opted in continuously for at least 14 days" before applying for production access. Plan that time into the launch.

Cost driver 5: upkeep every year

An app is never finished. Plan a yearly budget for:

• Operating system updates. Each new iOS and Android version can change behavior.
• Store requirements. Google Play sets a target API level each year. Since August 31, 2026, Google says "new apps and app updates must target Android 16 (API level 36) or higher" to be submitted, with lower levels for Wear OS, TV, XR and Automotive apps. Existing apps "must target Android 15 (API level 35) or higher to remain available to new users" on newer versions of Android. An app nobody updates eventually cannot ship fixes and stops reaching new customers.
• Hosting and services: servers, databases, email and SMS providers, map or AI usage.
• Bug fixes and small improvements based on what users actually do.

How to scope a first version

The cheapest way to build an app is to build less of it first. Use this checklist:

1. Write the one job. "Clients can book and pay for a visit" is a job. "An app for our business" is not.
2. List every feature, then mark each one must-have or later. Be strict: must-have means the app is useless without it.
3. Pick platforms from your users. Check your website analytics for the iPhone and Android split among your customers.
4. List integrations and confirm each system has an API you are allowed to use.
5. Decide who runs the admin side and what they need to do daily.
6. Agree on what success looks like after three months: bookings, active users, hours saved.

Give the same document to every company you ask for a quote. Then the quotes are comparing the same app.

A hypothetical example of step 2, for a home care agency that wants a family app. Must-have: sign-in, the visit schedule, a message to the office, account deletion. Later: live caregiver tracking, in-app payments, a chat assistant. The second list holds three of the heaviest features in this guide (real-time, payments and AI), which is why moving them to a later version changes the quote more than any negotiation will.

Questions to ask anyone quoting your app

• Which platforms and which framework, and why?
• Is the backend and admin panel included?
• Who owns the code and the store accounts?
• What is included after launch, and what does yearly upkeep cover?
• How do you handle store review rejections?
