If you’ve started pricing out an app, you’ve probably noticed the answers online are all over the map — anywhere from a few thousand dollars to half a million. That’s not very helpful when you’re trying to budget a real project.

So let’s cut through it: here are honest 2026 numbers, what actually moves the price, and how a modern team can build the same product for a fraction of what it would have cost just a few years ago.

The short answer

Most custom apps in 2026 land between $10,000 and $250,000, depending on scope. Here’s a realistic breakdown:

At Philex, we start custom builds — including full web apps — at around $10,000, because we build the smart way. Here’s what that means for your budget.

What actually drives the price

Five things move the cost more than anything else:

1. Number of features and screens. Every screen, form, and user role adds design, build, and testing time. A focused tool is far cheaper than an everything-app.
2. Platforms. Web only? iOS and Android? Building each one separately is what historically doubled budgets.
3. Integrations. Payments, maps, CRMs, third-party APIs — each connection adds work.
4. AI features. Smart search, recommendations, chat, document processing — powerful, and a real value-add, but they add scope.
5. Ongoing maintenance. Plan for roughly 15–25% of the build cost per year to keep an app secure, updated, and running smoothly.

How modern teams build apps for less

This is where the price gap between a dated agency and a modern one shows up — and where Philex keeps your cost down without cutting quality.

One codebase with Flutter & React. We build cross-platform, so a single codebase runs on iOS, Android, and the web. Instead of paying two or three teams to build the same app three times, you pay once. That alone can cut a project roughly in half.

AI-accelerated development. We use the latest AI development tools to scaffold, test, and ship faster. Fewer hours means a lower price passed on to you — and more of the budget spent on the parts that actually matter to your users.

Web apps first. A web app runs in any browser, on any device, with nothing to download. For most businesses it’s the fastest, most affordable way to launch, prove the idea with real users, and grow from there — which is exactly why our builds can start around $10,000.

The costs people forget to budget for

A great app still needs a great home. Two ongoing items belong in every plan:

• Hosting & infrastructure — and this is a Philex strength. We run the latest cPanel, put a Cloudflare firewall and CDN in front of your app, and layer in advanced server-side caching, so your product is fast and protected from day one.
• Maintenance & updates — small, predictable, and far cheaper than emergency fixes later.

So what will your app cost?

Honestly? It depends on what you’re building — and anyone who quotes you a hard number before understanding your idea is guessing. But you don’t need to commit to a project to get clarity.

Frequently asked questions

Can you really build an app for $10,000?
Yes — a focused web app or MVP with a clear set of features fits that range. The trick is building the right first version, not everything at once. We’ll help you scope it.

Is a web app cheaper than a mobile app?
Usually, yes. A web app skips the app stores, runs everywhere through the browser, and uses one codebase — which is why it’s often the smartest place to start.

How long does it take?
A web app or MVP typically takes 4–10 weeks. Larger platforms run a few months. We work in stages so you see progress early and often.

Do AI features cost more?
They can add scope — but the right AI feature often pays for itself. We’ll tell you honestly whether it belongs in version one or version two.

Who owns the code?
You do. Always.
