How much does it cost to pay someone to build a mobile app?

A focused MVP typically starts around $15,000. Full-featured apps with custom integrations and multi-platform deployment range from $50,000 to $250,000+. We provide a fixed-price quote after a free discovery call.

How long does it take to build a mobile app?

Most of our mobile app development projects launch in six to eight weeks from kickoff. Simpler MVPs can ship faster, while complex enterprise applications with extensive integrations may take 12-16 weeks. Our agile sprint process means you'll see working software within the first two weeks, not just wireframes.

Do I need an LLC to start an app?

You do not need an LLC to begin development, but we recommend forming one before launch to protect your personal assets and simplify app store registration. An Ohio LLC can be filed online for around $99.

How to create mobile apps that make money?

Start with a validated problem and a clear monetization strategy -- subscriptions, in-app purchases, advertising, or transaction fees. We help businesses identify the right model during discovery and build the analytics to support it.

Do you serve businesses outside London?

Yes. While our office is in London, we serve businesses throughout Pickaway County, the Columbus metro area, and across Ohio. We also work with clients nationally.

Do you build for both iOS and Android?

Yes. We offer iOS app development using Swift, Android app development using Kotlin, and cross-platform apps using Flutter and React Native. Many clients choose cross-platform development to reach both audiences simultaneously while keeping costs and timelines manageable.

What's the difference between native and cross-platform app development?

Native app development builds separate codebases for iOS (Swift) and Android (Kotlin), delivering the fastest performance and tightest platform integration. Cross-platform development with React Native or Flutter uses one shared codebase to ship to both app stores, cutting time-to-market and cost by roughly 30-40%. Choose native when peak performance or deep hardware integration matters most, and choose cross-platform when speed, budget, and maintaining a single team are the priorities.

How long will it take to build and launch my app in London?

We typically launch apps within 6 to 8 weeks, depending on the complexity and features of your project. Our streamlined development process ensures that you can bring your app to market quickly while still receiving a high-quality product.

What platforms do you develop for in London?

Our cross-platform development method allows us to create both web and mobile applications simultaneously. This means your mobile app will be available on both iOS and Android, ensuring a broad reach and a seamless user experience across all devices. Our approach helps you save time and resources while maximizing your app's potential.

How can I ensure my app is secure in London?

Security is a top priority for us. We implement industry-standard security measures, including data encryption, secure coding practices, and regular security audits, to protect your app and user data.

Do you provide ongoing support, maintenance, and updates in London?

Yes, we offer ongoing support, maintenance, and updates for your app. After completing your project, you will receive up to 4 weeks of complimentary maintenance to ensure everything runs smoothly. Following this period, we provide flexible ongoing support options tailored to your needs, so you can focus on growing your business while we handle your app's maintenance and updates.
