Mobile app development cost is the first question almost every founder and product owner asks, and the honest answer is always "it depends on scope." That answer alone does not help you plan a budget, though. This guide breaks down what actually drives the price of an app in 2026, which decisions push it up or down, and what to check before you sign a quote.
What drives mobile app development cost
An app's price is essentially the sum of engineering and design time. These factors have the biggest impact on that time:
- Feature scope: Every module such as payments, chat, maps, push notifications or user roles is a separate workload.
- Platforms: iOS only, Android only, two native apps or one cross-platform codebase (Flutter, React Native) each have a different cost profile.
- Design depth: A clean interface built from standard components takes far less time than a fully custom, animated brand experience.
- Backend and integrations: Your own API, an admin panel, ERP or CRM integrations and third-party services can make up a large share of the budget.
- Security and compliance: Payments, health data or strict privacy requirements add architecture and testing work.
Team structure and seniority
The same scope is priced differently by different teams. A senior team may look more expensive per hour, but it often costs less overall because it gets architectural decisions right the first time. A balanced team with a project manager, designer, mobile developer, backend developer and QA is more predictable than one person doing everything. Ask each vendor which roles are included and how much time each role gets.
AI features
Many apps in 2026 include AI features such as chat assistants, smart search or image recognition. Beyond the integration work, these features carry a variable running cost, usually per-request model fees, that grows with your user base. Budget for both.
Indicative price ranges by project type
The table below is not a price list. It is a rough frame based on common project types; actual quotes vary with team seniority, region and timeline.
| Project type | Typical scope | Indicative budget | Typical timeline |
|---|---|---|---|
| Simple MVP | 5–10 screens, login, basic content, notifications | Roughly 8,000–25,000 USD | 6–10 weeks |
| Mid-size app | Payments, profiles, admin panel, integrations | Roughly 25,000–70,000 USD | 3–5 months |
| Complex product | Real-time features, multiple roles, AI, offline sync | 70,000 USD and up | 5+ months |
The ranges are wide on purpose: "mid-size" can mean very different workloads in two different products. A written scope is the only way to get a firm number.
Native vs cross-platform and your budget
If you need both iOS and Android, a cross-platform approach usually lowers total cost thanks to a shared codebase. For deep device work such as Bluetooth, background processing or platform-specific widgets, native development tends to be more predictable. We compare the options in detail in our React Native vs native guide.
On a tight budget, another option is launching on the platform your audience uses most, then adding the second platform once the product is validated. If you go this way, design the backend and API to be platform-agnostic from day one.
Hidden costs to include
- Store accounts: The Apple Developer Program costs 99 USD per year and a Google Play developer account is a one-time 25 USD fee. See our guide on opening an App Store developer account.
- Hosting and services: Cloud hosting, databases, storage, push and email services grow with your user base.
- Store commissions: Apple and Google take a cut of in-app digital sales, typically 15 percent under small business programs and 30 percent at the standard rate.
- Maintenance: New iOS and Android versions ship every year and dependencies need updates. Plan an annual maintenance budget from day one.
- QA and devices: Testing across screen sizes and OS versions takes real time, especially on Android.
How to keep the budget under control
- Start with an MVP that proves the core value, then prioritize the rest using real user data.
- Finish design first. A clickable prototype reduces rework during development; time spent on UI/UX design usually pays for itself.
- Use proven services for authentication, payments and analytics instead of building everything from scratch.
- Manage scope changes in writing, since every mid-project feature affects both timeline and cost.
Questions to ask before accepting a quote
- Which screens and features are included, and what is explicitly out of scope?
- Who owns the source code and intellectual property?
- How is testing done and on which devices?
- What warranty and maintenance terms apply after launch?
An unusually low quote often signals a misunderstood scope or missing testing and maintenance. The cheapest option can become the most expensive one later.

Frequently asked questions
How much does the simplest app cost?
A small MVP with a few screens, login and basic content usually sits at the lower end of the range. The exact number depends on design expectations, backend needs and how many platforms you target.
Are there ongoing costs after launch?
Yes. The Apple developer membership renews yearly, hosting and third-party services are billed monthly, and the app needs regular maintenance to stay compatible with new OS versions.
Does building for iOS and Android double the cost?
With two native codebases the cost rises significantly. With a cross-platform framework such as Flutter or React Native, most code is shared and the increase is much smaller.
Is fixed price or time and materials better?
Fixed price works well when scope is clear and stable. Time and materials or sprint-based billing is more flexible when the product will evolve based on user feedback.
