"How much does it cost to build an app?" is the most common question we hear, and the honest first answer is another question: what kind of app? Asking the cost of "an app" is like asking the cost of "a building" — a one-room shop and a shopping mall are both buildings. The good news is that the things which decide the price are easy to understand. Once you know them, you can read any quote properly and spot where the numbers come from. This guide explains those factors honestly, without throwing invented price tags at you.
1. What the app actually does
Features are the biggest driver of cost, because each one is work to design, build and test. A simple app — a few screens showing information, a form, a catalogue — is modest. Costs climb as you add things like:
The practical takeaway: list your features as "must-have" versus "nice-to-have." Launching with the must-haves first keeps the first cost down and lets real users tell you what to build next.
2. One platform or two
An app can run on Android, on iPhone (iOS), or both. Building two fully separate apps roughly means two lots of work. This is why many businesses choose cross-platform development, where a single codebase serves both Android and iPhone — it usually costs less than two native apps while still reaching everyone. If your customers are overwhelmingly on one platform, starting there is a fair way to save; if they are split, leaving one out means leaving out real users.
3. Design — template or custom
A standard, clean design using familiar patterns is quicker and cheaper. A distinctive, branded experience with custom screens, animations and illustrations takes more design time and so costs more. Neither is "right" — a straightforward internal tool does not need a showpiece interface, while a consumer app competing for attention often does. Decide how much the look is worth to your particular app.
4. The part users never see: the backend
Most real apps are only half an app on the phone; the other half is the backend — the servers, databases and logic that store data, handle logins, process payments and talk to the admin panel. The more your app remembers, syncs or processes, the more backend work it needs, and this is often where cheap quotes quietly cut corners. If a quote looks surprisingly low, the backend is the first place to check what is missing.
5. Integrations with other services
Apps rarely stand alone. Connecting to a payment gateway, an SMS or WhatsApp service, maps, a delivery partner, or your existing billing or accounting system all add work. A couple of simple integrations are routine; many complex ones, each with its own rules, add up. List the outside services your app must talk to early, because they shape both cost and timeline.
6. Testing and quality
Good apps are tested across different phones, screen sizes and conditions before release. Skipping this is how an app ends up with one-star reviews for crashing on launch day. Proper testing is part of any honest quote — if it is not mentioned at all, ask where it is.
7. The cost that comes after launch
This is the one most people forget. An app is a product you run, not a one-time purchase. Budget, every year, for:
A team that mentions these upfront is being straight with you; one that pretends the app is "done" at launch is not.
Why one honest quote beats a quick number
You should be wary of a firm price offered before anyone understands what you are building — it is either padded to be safe, or set to win the deal and grow later through "extras." A serious partner asks about your features, platforms, integrations and backend first, then returns a written estimate broken into modules and milestones, so you can see exactly what each part costs and decide what to keep, cut or postpone. That is how you compare quotes fairly: by what is included, not by the headline figure.
Getting a real number for your app
The fastest way to a reliable figure is a short conversation about what you want the app to do, followed by a written, itemised estimate. If you want that for your idea — plus an honest view on whether to start with Android, iPhone or both, and which features to launch with first — read about our mobile app development work, or talk to our team in Jaipur. If your project is really custom business software with an app on top, our software development page covers that side too.
Frequently Asked Questions
Because "an app" can mean a simple two-screen tool or a full marketplace with payments, chat and live tracking. The price follows the features, platforms and backend you need. A serious company asks about those first, then gives a written estimate broken into modules.
Building for one platform costs less than two, yes. But if your customers use both Android and iPhone, launching on one leaves out real users. Cross-platform tools can cover both from one codebase and often cost less than two fully separate apps.
Not always, but a quote far below the rest usually means something is missing — often the backend, testing, or post-launch support. Compare what each quote includes, not just the number. The cheapest build often costs more once you add what was left out.
Plan for app store fees, hosting and backend running costs, and maintenance for updates, fixes and new phone or OS versions. An app is a product you run, not a one-time purchase, so keep a yearly budget for keeping it healthy.
