The honest answer is that a mobile app can cost anywhere from a few thousand to well over a hundred thousand, and that range is useless on its own. What you actually want to know is where your app sits and why. This is the breakdown we walk people through before anyone commits to a number.

What you are actually paying for

An app is rarely just the screens you see. The cost spreads across a few areas, and most surprises come from the parts that are easy to forget at the idea stage:

The app: the screens, navigation, and interactions your users touch every day.
The backend: accounts, data, and the API the app talks to. Most apps need one, even when it is not obvious from the outside.
Integrations: payments, push notifications, analytics, maps, anything that connects to a third party.
Release work: store accounts, review, test builds, and the back and forth it takes to actually go live.

Realistic ranges in 2026

For a custom app built properly, here is roughly what to expect. These line up with our packages:

A focused first version (MVP): around 9,500 to 25,000 USD. One core workflow, accounts, payments if you need them, and a clean store release.
A fuller product: 25,000 USD and up. Several workflows, a heavier backend, deeper integrations, and ongoing iteration after launch.

If a quote for a custom build comes in far below this, it usually means corners somewhere: no real backend, no testing, or a template you will outgrow within months.

What moves the price up or down

A few factors drive most of the difference between two quotes:

How many distinct features and screens the app has.
Whether it needs a custom backend or can lean on existing services.
Real-time features like live updates or alerts, which add backend work.
Payments and subscriptions, which need careful setup and testing.
Whether you launch on iOS, Android, or both.

That last point matters less than most people expect. We build with React Native and Expo, so a single codebase covers iOS and Android. You are not paying twice to reach both stores.

How to keep the budget under control

The most reliable way to control cost is to narrow the first version. Ship the one workflow that proves people want this, learn from real usage, then spend on the rest with evidence instead of guesses. We go deeper on that in turning an app idea into a real product.

If you would rather have a real number than a range, tell us what you are building and you will get back a scoped proposal with a fixed plan and timeline.
