The cost to build a mobile app depends mostly on how many features it has, how many platforms it targets, and how much back-end it needs. A simple single-platform app typically starts in the low tens of thousands of dollars, a standard app with a few integrations and both iOS and Android commonly runs into the mid tens of thousands and up, and a complex app with custom back-end, AI, or compliance costs more. The biggest lever is scope: fewer features and one platform first means a lower cost.
Fewer features and one platform first means a lower cost.
iOS only or Android only is cheaper than both; cross-platform frameworks can cover both more efficiently than two native builds.
An app that needs servers, accounts, and data sync costs more than a standalone app.
The rough ranges below set expectations only; your real estimate comes from scoping the features.
What drives mobile app cost
Native vs cross-platform and cost
Building separately for iOS and Android (native) gives the most control. A cross-platform approach builds once for both and often lowers cost, with trade-offs for the most demanding apps. (See Native vs Cross-Platform Mobile Development.)
Native
Separate builds for iOS and Android
- Gives the most control
- One build for iOS and one for Android
Cross-platform
One build for both
- Often lowers cost
- Covers both more efficiently than two native builds
- Trade-offs for the most demanding apps
Rough ranges
Expectation-setting only; your real estimate comes from scoping the features.
| App type | What it looks like | Typical range |
|---|---|---|
| Simple app | One platform, few screens, minimal back-end | Low tens of thousands |
| Standard app | Both platforms, accounts, a few integrations | Mid tens of thousands and up |
| Complex app | Custom back-end, AI, or compliance | Higher, scoped case by case |
How to build a mobile app affordably
- Start with an MVP. Build the core that proves value first, then expand. (See What Is an MVP.)
- Pick one platform first if budget is tight, then add the second once you have traction.
- Use a fixed discovery to get a firm price and plan before committing.
- Cut features ruthlessly for version one; every extra is hours.
- Do not chase the cheapest bid; underbuilt apps cost more in rework and rejected app-store submissions.
What you are paying for
App-store-quality, secure, maintainable software is engineering, not a template. The expensive version of a cheap app is the one that crashes, leaks data, or gets rejected and has to be rebuilt. Budget for quality in the core, then grow.
Figure 1. The layers a mobile app budget pays for
Each layer comes from the cost drivers above: every screen and feature is engineering time, each integration adds work, security and compliance are part of the core build, and a simple standalone app needs no back-end.
Mobile app cost FAQs
How much does it cost to make an app?
It depends on features, platforms, and back-end. A simple single-platform app starts in the low tens of thousands; both platforms with integrations runs mid tens of thousands and up; complex apps cost more. A scoped discovery gives the real figure.
Is it cheaper to build for one platform?
Yes. One platform is cheaper to start; cross-platform frameworks can also cover both more efficiently than two native builds.
How can I reduce mobile app cost?
Start with an MVP, pick one platform first, scope a fixed discovery, and cut features for version one.
Does a mobile app need a back-end?
Many do, for accounts, data, and sync, and that back-end is part of the cost. Simple standalone apps do not.
