Free App & Software Development Cost Calculator

What decides the cost of an app

Three things move the price more than anything else: how many platforms you launch on, which features you need and how much custom logic sits behind the screens. A booking app with login, a calendar and notifications has a far smaller build than a marketplace with payments, chat, live tracking and separate apps for buyers and sellers.

Every feature brings its own screens, server work and testing. Payments need a gateway account, failure handling and refunds. Chat needs real-time messaging and storage. Maps need location permissions and an API key with its own usage charges. The card shows each line so you can see where the money goes and drop what can wait for a second phase.

Android, iOS or both?

Most Indian consumer apps start on Android because that is where most of their users are. Business apps used by staff often need only Android too, since the company chooses the phones. If your customers include many iPhone users, or you sell to premium buyers, launching on iOS at the same time makes sense.

Cross-platform frameworks such as Flutter or React Native let one codebase serve both Android and iOS, which keeps the second platform cheaper than building it twice. You still pay for extra testing on real devices, store listings and the differences in how each platform handles notifications and payments.

Choosing the right complexity level

Pick Simple when the app has a handful of screens, standard sign-up and mostly shows or collects information. Pick Standard when you want a custom design, several user roles and business rules such as approvals, discounts or stock checks. Pick Complex when the app runs heavy calculations, real-time updates, large data volumes or integrations with older systems.

If you are torn between two levels, choose the higher one for budgeting. It is easier to come in under a plan than to find extra money halfway through a build.

Costs the calculator leaves out

The range covers design, development and testing of the features you select. It does not include app store developer accounts, server hosting, SMS or WhatsApp message charges, map API usage or payment gateway fees, because those depend on your usage and are paid to the providers. Content such as product photos, translations and legal pages also sits outside the estimate. We confirm support, hosting and licensing terms in the written quote.

How long app development takes

The timeline on the card grows with the number of features you pick. It shows a low and a high figure because feedback rounds, content readiness and app store review times vary. A clear feature list before work starts shortens the build more than anything else, so try our free software requirements planner first if your scope is still loose.
