Everything You Need to Know Before Hiring App Development Firms

What can mobile app development companies do for your business?

A mobile application development company can help your business reduce product risk and accelerate growth by designing, building, and optimizing mobile user experiences that users want to return to.

Mobile app companies typically support your business in three ways:

1. Validate your app idea before you scale through discovery, prototyping, and MVP to test assumptions, confirm feasibility, and gather real user feedback early.
2. Build for retention through UI/UX design, performance engineering, and data analytics to remove friction and improve onboarding, engagement, and reliability, especially during peak usage moments.
3. Enable growth loops via lifecycle messaging (push notifications and in-app messages), experimentation, and iteration based on user behavior and outcomes.

According to eMarketer, 80% of US customers spend nearly 4x more time on mobile apps compared to mobile browsers, underscoring that apps are the primary engagement channel on mobile devices.

However, mobile apps have a high churn rate, with the top reasons for deletion being:

• Too many in-app ads (30%)
• Expectation not met (25%)
• Poor UX (18%)
• Too many notifications or in-app messaging (18%)
• Found a better app (18%)

On the other hand, top mobile app performers record:

• 13% higher engagement scores above industry benchmarks
• 72% average increase in sessions per active user
• 4% higher monthly active user growth

Ultimately, this translates to higher revenue, with global users spending up to $40.9 billion on mobile apps in the first quarter of 2025 alone.

How much does it cost to build a mobile app?

On average, a mobile app can cost between $20,000 and over $100,000, depending on software complexity, target users, features, functions, and technical requirements. The location and expertise of your custom mobile app development company also impact overall costs.

Below is the estimated hourly rate of app development firms for each region:

• Southeast Asia: $20-$45
• Eastern Europe: $30-$50
• Western Europe: $60-$120
• Latin America: $40-$160
• United States and North America: $100-$150

Based on the hourly rate above, here is how much you can expect to pay for different mobile app development projects:

• Basic MVP apps: $15,00-$25,000 for basic features like user login and static content forms.
• Simple apps: $20,000-$60,000 for internal use and $40,000-$90,000 for commercial releases. This includes basic UI and functions with low programming complexity.
• Medium complexity: $50,000-$120,000 for internal use and over $100,000 for commercial distribution. Features include interactive UI with multi-step user journeys and system integration.
• Highly complex apps: Over $200,000, and includes custom UI/UX design, complex back-end logic, and advanced security layers.
• eCommerce apps: $50,000-$150,000+, depending on the product catalog volume, number of integrations, and advanced features (e.g., AI recommendation engines)
• Healthcare and fintech apps: $60,000-$350,000+, often priced at the higher end due to the compliance and security measures needed.

How long does the app development process take?

Custom mobile app development can take 3 months to over 1 year to produce, depending on the software complexity, platform type, mobile app design, compliance requirements, and iteration cycle.

Below is an estimated timeline for different app development services:

• Basic MVP: 3-6 months for a basic dashboard or contact form. eCommerce app development also falls under this timeline.
• Moderate builds: 6-9 months for payment gateway and social media integrations, in-app messaging, and multi-language support. Examples include social media and dating apps.
• Advanced app complexity: 9-12 months for real-time data dashboards and role-based user access. Examples include 3D gaming apps.
• Enterprise builds: 12-18+ months for AI-based personalization or recommendations, real-time data processing, complex backend infrastructure, and integration into several business systems. Examples include SaaS and blockchain apps.

How to choose the right app development company for your business?

To choose the right app development company for your business, assess its technical capabilities, proven expertise, and pricing structure against your goals and needs. Here are some steps to aid your decision-making process:

1. Clarify your project goals and needs, including use cases, target users, platform type, priority features and functionalities, and integration requirements.
2. Seek expertise in your industry, app type, and technical requirements by evaluating their case studies. Also, review how the app developer describes their process and business impact.
3. Read their client reviews and references to understand their project management approach, problem-solving skills, and service delivery. Also, long-term client relationships show that the company is dependable.
4. Send a request for proposal and detail your goals, timeline, budget range, and requirements. Compare proposals and shortlist 5 that provide the best value for money.
5. Interview the team working on your app to learn about their team structure, approach to your project, and post-launch support services.
6. Start with a pilot project, such as a prototype or MVP, to further confirm project and business fit before signing a full-scale development contract.
