How much does a custom iOS and Android app cost?

The cost of building a custom app for both iOS and Android can vary widely. A simple app with basic functionality, like a calculator or a note-taking app, might start around $15,000. However, apps with more complex features such as user accounts, real-time data synchronization, custom animations, payment gateway integrations, or AI-powered components can easily push the cost upwards of $60,000, and sometimes even $100,000+ for very sophisticated platforms.

Several factors influence the price:

What is the timeline for custom app development?

The timeline for custom iOS and Android app development is just as variable as the cost. A basic app might take 3 to 4 months from concept to launch. More complex applications, especially those requiring extensive backend infrastructure, advanced features, or multiple integrations, can take anywhere from 6 to 9 months, or even longer.

A typical development process includes these phases:

When should you build a custom app instead of using an existing solution?

You should consider building a custom app when existing off-the-shelf solutions don't meet your specific business needs or when you have a unique idea that requires a tailored approach. If your business processes are highly specialized, or if you need to integrate deeply with your existing internal systems in a way that generic software cannot accommodate, custom development is often the best path forward.

Consider custom development if:

For many businesses, the first step is a Discovery Sprint. This focused, short-term engagement helps define the scope, features, and technical feasibility of your app idea. It’s an efficient way to get clarity on what a custom solution would entail without committing to the full build upfront. A Discovery Sprint typically costs between $2,500 and $5,000.

What are the key features to consider for a custom app?

The key features depend entirely on your business goals and target audience. However, common features that add significant value include:

Factors influencing this price include the number of features, platform complexity, UI/UX design, backend development needs, third-party integrations, and the development team's location and expertise.
How long does it take to develop a custom app for iOS and Android?
The timeline for custom app development typically spans 3 to 9 months. A simple app might take 3-4 months, while complex applications with extensive backend infrastructure or advanced features can take 6-9 months or longer. The process involves phases like discovery, design, development, testing, and deployment.
When should a business opt for custom app development over existing solutions?
Businesses should consider custom app development when off-the-shelf solutions don't meet specific needs, or when a unique idea requires a tailored approach. This is ideal for specialized workflows, integration with proprietary systems, creating a unique brand experience, or when the app is a core revenue-generating tool.
What are the key phases in the custom app development process?
The typical custom app development process includes: Discovery & Planning (2-4 weeks), UI/UX Design (3-6 weeks), Development (2-6 months), Testing & Quality Assurance (3-5 weeks), and Deployment & Launch (1-2 weeks). Post-launch support and maintenance are also crucial.
